Ep 151 - October 2019 Round Up
St Emlyn's October 2019 Round-Up: Key Insights from Conferences and Research October 2019 was a bustling month for the St Emlyn's team, filled with important conferences, groundbreaking research, and engaging discussions in emergency medicine. This round-up covers the highlights, from tactical trauma insights to controversial trial results, providing a comprehensive overview of the month’s most significant developments. Tactical Trauma Conference in Sundsvall, Sweden The month started with the Tactical Trauma Conference in Sundsvall, Sweden, where Pete Hume, a colleague from Virchester, presented on the response to the Manchester Arena bombing. This tragic event, involving many pediatric casualties, posed significant challenges in managing a high volume of injured children. Pete’s presentation highlighted the crucial lessons learned during the response, emphasizing the importance of preparedness and efficient resource management. A standout talk at the conference was given by Geoff Yost, who discussed the 2017 Las Vegas shooting. A key takeaway from his presentation was the importance of utilizing bystanders during mass casualty incidents. Bystanders are often the first to respond, and their actions can significantly influence outcomes. This was exemplified by the recent London Bridge attack, where members of the public intervened using improvised weapons like a narwhal tusk. Pete also provided insights into leadership in crisis situations, a topic covered by Kate Pryor at the conference. Overall, the Tactical Trauma Conference underscored the need for collaboration with bystanders and the importance of effective leadership during emergencies. R.CEM Annual Scientific Conference in Gateshead The R.CEM Annual Scientific Conference, held in Gateshead at the end of October, brought together emergency clinicians, nurses, paramedics, and researchers to discuss the latest developments in emergency medicine. Chris Gray, a member of the St Emlyn's team, attended and shared his experiences through a series of blog posts. One of the most anticipated studies discussed at the conference was the NOPE PAX study on the use of tranexamic acid for treating nosebleeds. Although the results are not yet publicly available, the study is expected to provide valuable insights into this increasingly popular treatment. Another key study was the CAP-IT study, which focuses on the use of antibiotics in pediatric pneumonia—a topic of ongoing debate in the context of antibiotic stewardship. The conference also featured discussions on the CRASH-3 trial, particularly concerning the use of tranexamic acid in traumatic brain injury. Ian Roberts delivered a compelling presentation on the mechanisms of tranexamic acid and the significant differences in its use across various regions, including the UK, the US, and Australasia. The TERN Network and the TIRED Study A major highlight of the R.CEM conference was the presentation of the TIRED study, the first major project from the Trainees Emergency Research Network (TERN). Led by Dan Horner, the study surveyed the levels of fatigue among emergency physicians across the UK, using the Need for Recovery Score to assess recovery time after shifts. The study revealed concerning results, with emergency clinicians scoring an average of 73 on the Need for Recovery Score, significantly higher than the previous highest score of 55 recorded for Iranian miners. This suggests that emergency clinicians are under immense pressure, leading to high levels of fatigue. Interestingly, older clinicians had lower scores, indicating either greater resilience or better workload management. However, the study raises the controversial question of whether the job’s demands are causing some clinicians to leave the profession early. The TERN network is continuing to explore critical questions in emergency medicine, with upcoming studies on subarachnoid hemorrhage and the necessity of lumbar punctures. European Resuscitation Council Meeting in Slovenia The European Resuscitation Council meeting in Slovenia was another key event in October. The chain of survival—early recognition, CPR, defibrillation, and post-resuscitation care—was a major focus of the conference. While much attention is often given to post-resuscitation care, the most significant impact on survival comes from the early stages of the chain. The GoodSAM app, which allows trained responders to be notified of nearby emergencies, plays a crucial role in this early response. The app has already made a significant difference in several cases, including cardiac arrests. Another important discussion at the conference was the use of hypothermia in post-cardiac arrest care. Following the TTM1 trial, which suggested that hypothermia might not be as beneficial as once thought, some clinicians have stopped temperature management altogether. However, evidence presented at the ERC meeting indicates that this may have led to an increase in post-arrest mortality. The ongoing TTM2 trial aims to provide more clarity on the role of hypothermia in post-cardiac arrest care. Thromboprophylaxis in Lower Limb Immobilization Dan Horner’s study on thromboprophylaxis in lower limb immobilization is another significant piece of research published this month. The study, a systematic review, highlighted that the incidence of significant deep vein thrombosis (DVT) in patients with lower limb immobilization is around 2%, and anticoagulation almost certainly reduces this risk. However, the study also pointed out that there is no clear consensus on which risk stratification tool is best for identifying patients at risk of DVT. The GemNet guidelines from R.CEM are a solid option, but more research is needed in this area. The study also discussed the choice of anticoagulant, noting that while low-molecular-weight heparin is the most commonly used, the use of DOACs, such as rivaroxaban, is on the rise. As an emergency physician, the balance between preventing life-threatening complications like pulmonary embolism and avoiding significant bleeding events remains a critical consideration in patient care. Top 10 Papers from 2018-2019 The R.CEM Annual Scientific Conference also featured a presentation on the top 10 papers from the past year, covering a wide range of topics in emergency medicine. One key study explored whether early or delayed cardioversion should be performed in recent-onset atrial fibrillation, with the conclusion leaning towards not immediately intervening. Another study examined whether ventilation should continue during RSI (rapid sequence induction), with evidence suggesting that it should. The debate over cricoid pressure during RSI continues, with recent evidence indicating that it may not be necessary and could even be harmful in some cases. Magnesium in atrial fibrillation was also discussed, with the evidence supporting its use, particularly when combined with other treatments. The presentation also covered the use of vasopressors in hemorrhagic shock, with early evidence suggesting they might be beneficial, though more research is needed. Finally, the discussion touched on diagnosing pulmonary embolism in pregnancy using the YEARS score, a promising but still developing area of research. The CRASH-3 Trial: A Controversial Conclusion The CRASH-3 trial, focusing on the use of tranexamic acid in traumatic brain injury, has generated significant debate in the emergency medicine community. While the trial’s findings have already started to influence practice in the UK, the way the results were interpreted and publicized has been controversial. The debate centres around two main camps: one that argues the trial didn’t conclusively prove that tranexamic acid reduces mortality in traumatic brain injury and another that believes the evidence strongly suggests a benefit in certain subgroups. While not the final word on the subject, the CRASH-3 trial provides enough evidence to justify the use of tranexamic acid in specific scenarios. Looking Ahead As October ends and November begins, there’s much to look forward to. The Asian Conference of Emergency Medicine in India promises to be an exciting event, and the Resuscitology Conference in December is already sold out, with plans to run it again in 2020. Emergency medicine is more intense than ever, with record numbers of patients and some of the toughest days experienced in the field. Despite these challenges, the St Emlyn's team continues to provide exceptional care and remain at the forefront of emergency medicine research and practice. Thank you for following along with this month’s round-up. Stay tuned for more updates from St Emlyn's as we continue to explore, learn, and share the latest in emergency medicine. 4o

Ep 150 - REBOA with Zaf Qasim
Simon and Zaf talk about the practicalities of REBOA and discuss whether it's ready for prime time in the UK. Introduction Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a minimally invasive technique designed to control hemorrhage in patients with life-threatening bleeding and offers a bridge to definitive surgical intervention. Here at St Emlyn’s, we are committed to exploring innovative solutions that enhance patient outcomes in emergency medicine. In this post, we delve into the essentials of REBOA, its clinical application, benefits, and challenges. Understanding REBOA REBOA involves the insertion of a balloon catheter into the aorta via the femoral artery. By inflating the balloon, we can occlude the aorta, thus controlling bleeding below the point of occlusion. This procedure is particularly useful in cases of non-compressible torso haemorrhage, where traditional methods of haemorrhage control are inadequate. Indications and Contraindications Indications: Hemorrhagic shock from pelvic fractures or abdominal bleeding. Trauma patients with signs of severe hemorrhage unresponsive to fluid resuscitation. As a temporary measure until surgical control of bleeding is achieved. Contraindications: Patients with known aortic pathology (e.g., aortic dissection). Significant injury above the diaphragm. Prolonged transport times where REBOA may not be beneficial. The Procedure Preparation Before performing REBOA, it is crucial to ensure that the patient is appropriately resuscitated and stabilized as much as possible. This includes securing the airway, ensuring adequate ventilation, and achieving initial hemodynamic stabilization. Insertion and Inflation Vascular Access: Gain access to the common femoral artery using ultrasound guidance to minimize complications. Catheter Insertion: Insert the REBOA catheter through a sheath into the femoral artery. Advance the catheter under fluoroscopic or ultrasound guidance to the desired level in the aorta (Zone I: above the celiac artery for abdominal hemorrhage, Zone III: above the bifurcation of the iliac arteries for pelvic hemorrhage). Balloon Inflation: Inflate the balloon to occlude the aorta. This temporarily controls bleeding and allows time for definitive surgical repair. Monitoring and Maintenance Continuous monitoring of vital signs and catheter position is essential. The occlusion time should be minimized to reduce ischemic complications. Ideally, REBOA should serve as a bridge to definitive surgical intervention within 30-60 minutes. Benefits and Challenges Benefits Rapid Hemorrhage Control: REBOA can quickly control bleeding, buying crucial time for surgical intervention. Less Invasive: Compared to traditional open thoracotomy with aortic cross-clamping, REBOA is less invasive, reducing associated morbidity. Improved Survival Rates: Emerging evidence suggests that REBOA can improve survival rates in appropriately selected trauma patients. Challenges Technical Expertise: REBOA requires specific training and expertise. Improper technique can lead to significant complications. Ischemic Complications: Prolonged aortic occlusion can lead to ischemia of distal organs and tissues, necessitating careful monitoring and timely deflation. Resource Intensive: REBOA demands resources such as fluoroscopy, ultrasound, and trained personnel, which may not be available in all settings. Conclusion REBOA represents a promising advancement in trauma care, offering a vital tool in the management of life-threatening haemorrhage, but it's utility in the Emergency Department is uncertain.

Ep 149 - September 2019 Round Up
A Month in Review: Key Takeaways from St Emlyn's September 2019 Content Welcome to a detailed overview of the latest content from St Emlyn's, focusing on the valuable insights and educational resources we shared throughout September 2019. This month’s offerings span a wide range of topics, from the evolving concept of the "resuscitationist" to the increasing challenges posed by decompensated liver disease, and the ongoing development of emergency medicine education. Here’s a look at the most important takeaways. The Resuscitationist: More Than Just a Title The term "resuscitationist" has become a buzzword within the emergency medicine (EM) and critical care communities, especially following its emergence from the SMACC (Social Media and Critical Care) conferences. Dan Horner delved into this concept in a recent presentation, sparking a broader discussion about what it truly means to identify as a resuscitationist. At its core, being a resuscitationist isn’t just about having an interest in the resuscitation room. It requires a blend of sharp clinical skills, deep knowledge of resuscitation science, and the ability to apply evidence-based practices effectively. But beyond technical expertise, leadership and teamwork are crucial. A resuscitationist must excel in managing high-stakes, chaotic situations where decisions are made with limited information and under intense time pressure. Moreover, Dan highlights the importance of humility and collaboration. The best resuscitationists are those who recognize their own limitations and are skilled at drawing on the strengths of others, whether from different specialties or professions. This collaborative approach not only enhances patient care but also builds stronger, more effective resuscitation teams. Decompensated Liver Disease: A Growing Concern in the ED Liver disease is on the rise, particularly due to lifestyle factors like alcohol consumption and obesity. Gareth Roberts tackled this pressing issue in his blog post on decompensated liver disease, which is becoming increasingly common in emergency departments (EDs) across the UK and beyond. Gareth outlines a comprehensive care bundle designed to manage patients with decompensated liver disease effectively. This bundle includes seven key points: Thorough Investigation: Quick and accurate investigations are essential, particularly for detecting complications like spontaneous bacterial peritonitis (SBP), which can be life-threatening. Infection Management: Aggressive treatment of infections is critical, with a focus on using appropriate antibiotics and monitoring for SBP. Acute Kidney Injury (AKI) and Hyponatremia: These complications are common in liver disease patients and must be managed carefully. Gareth discusses the potential benefits of human albumin in these cases. GI Bleeding: Gastrointestinal bleeding, especially from varices, poses a significant risk. Gareth directs readers to additional resources on St Emlyn’s, including a presentation by Chris Gray on managing GI bleeding. Hepatic Encephalopathy: This condition can severely alter a patient’s mental status and requires careful management. With the increasing prevalence of liver disease, understanding and managing hepatic encephalopathy is more important than ever. Gareth’s post is a must-read for anyone dealing with liver disease in the ED, providing both practical advice and links to further resources. Expanding Education: The MSc in Emergency Medicine Education is a cornerstone of St Emlyn’s, and we’re excited to announce the expansion of the MSc in Emergency Medicine at Manchester Metropolitan University. This program has been running successfully for several years and is now broadening its scope to include paramedics, making it a truly multi-professional and multi-disciplinary course. The MSc program offers a variety of modules tailored to the specific needs of different healthcare professionals. Whether you’re looking to deepen your clinical knowledge, enhance your leadership skills, or explore new areas of emergency medicine, this program has something to offer. For more details, visit our website or reach out directly. Supporting St Emlyn’s: Keep Our Content Free and Accessible St Emlyn’s remains committed to providing free and open-access content to the global emergency medicine community. However, maintaining and expanding our offerings requires resources. If you find value in what we provide, please consider supporting us financially. Even a small contribution can help us continue to deliver high-quality content to healthcare professionals worldwide. Introducing Coda: The Next Evolution After SMACC Coda is the latest evolution in the SMACC legacy, aiming to broaden the scope of its predecessor by incorporating a wider range of specialties, including oncology, public health, and surgery. As a member of the Coda executive team, I can attest to the ambitious goals of this new conference series. Coda retains the clinical excellence that SMACC was known for, but with an added emphasis on advocacy. Each year, Coda will tackle a significant global health issue, with the inaugural theme focusing on climate change and its impact on medical practice. It’s important to note that while climate change is a key focus, it won’t dominate the entire conference. Only about 25% of the program will be dedicated to this theme, with the remaining 75% featuring the high-quality clinical content you’ve come to expect from SMACC. The first Coda conference is set to take place in Melbourne in 2020, and we encourage you to participate, whether in person or remotely. The Zero Point Survey: A Game-Changer in Resuscitation The Zero Point Survey, a concept championed by Cliff Reid, is gaining widespread recognition for its transformative impact on resuscitation practices. The idea shifts the focus of the primary survey in resuscitation from when you first encounter the patient to what you do before you even meet them. This approach emphasizes the importance of preparation—both mental and environmental. By optimizing everything you can control before the patient arrives, you set the stage for delivering high-quality care when it matters most. Feedback from the EM community has been overwhelmingly positive, with many clinicians reporting that the Zero Point Survey has changed how they manage the resuscitation room. It’s not just a theoretical concept; it’s a practical tool that’s making a real difference in patient outcomes. If you’re not yet familiar with the Zero Point Survey, I strongly encourage you to explore the resources available on the St Emlyn’s website, including an excellent video by Cliff Reid that outlines the key elements of this approach. Looking Ahead: What’s Next for St Emlyn’s? As we wrap up our review of September’s content, it’s clear that the St Emlyn’s team has been hard at work bringing you the latest in emergency medicine education and clinical practice. But there’s much more to come. In the coming months, we’ll be covering exciting topics at upcoming conferences, including the ArchiEM conference in Gateshead and the Slovenia ERC conference. These events promise to bring fresh insights and new perspectives that we’ll be sharing with you through our blog posts and podcasts. In the meantime, keep doing the incredible work you do in emergency medicine. It’s a challenging field, but it’s also incredibly rewarding, and you’re making a difference every day. Thank you for being part of the St Emlyn’s community, and I look forward to continuing this journey with you. Stay tuned for more great content, and as always, keep pushing the boundaries of what’s possible in emergency care.

Ep 148 - CRASH-3
The CRASH-3 Trial: Revolutionizing Head Injury Management with Tranexamic Acid The CRASH-3 trial, a landmark study in the field of emergency medicine, has brought significant attention to the potential role of tranexamic acid (TXA) in managing traumatic brain injury (TBI). As one of the largest randomized controlled trials ever conducted on head injury patients, its findings could reshape clinical practices globally, particularly in the pre-hospital and emergency department settings. Overview of the CRASH-3 Trial The CRASH-3 trial was designed to assess the efficacy of TXA in reducing mortality among patients with traumatic brain injury. TXA is an antifibrinolytic agent commonly used to prevent excessive bleeding in various medical scenarios, such as trauma, surgery, and postpartum hemorrhage. The question posed by CRASH-3 was whether TXA could also reduce deaths in patients who had suffered a TBI, a question that had remained unanswered despite the success of the CRASH-2 trial in managing extracranial bleeding. Patient Population and Inclusion Criteria The trial focused on adults aged 16 years and older who had sustained a traumatic brain injury. To be included, patients needed to have either a Glasgow Coma Scale (GCS) score of 12 or lower or a positive CT scan indicating intracranial bleeding. Notably, patients with significant extracranial bleeding were excluded from the trial to specifically measure the effect of TXA on TBI outcomes. A critical aspect of the trial was the timing of TXA administration. Initially, the protocol allowed TXA to be administered within eight hours of injury. However, as data from other studies like the WOMAN trial and CRASH-2 became available, suggesting that the benefits of TXA diminish after three hours, the protocol was adjusted. This change meant that the majority of patients received TXA within three hours of injury, a key factor in the study's final analysis. Key Findings of the CRASH-3 Trial The CRASH-3 trial enrolled 12,737 patients across 29 countries, making it one of the most extensive studies of its kind. The primary outcome measured was all-cause mortality at 28 days post-injury. The results showed that overall mortality was slightly lower in the TXA group (18.5%) compared to the placebo group (19.8%), although this difference was not statistically significant. However, a pre-specified subgroup analysis provided more compelling evidence. When patients with a GCS of 3 and bilateral unreactive pupils (indicating very severe brain injury) were excluded, TXA demonstrated a more significant benefit. In this subgroup, the mortality rate was 12.5% in the TXA group versus 14% in the placebo group, a statistically significant reduction with a relative risk of 0.89. This finding suggests that TXA is particularly beneficial for patients with moderate head injuries (GCS 9-15) who are more likely to survive if bleeding is controlled. Number Needed to Treat (NNT) One of the critical metrics for evaluating the effectiveness of a treatment is the number needed to treat (NNT). In the CRASH-3 trial, the NNT was 67, meaning that 67 patients would need to be treated with TXA to save one additional life at 28 days post-injury. For comparison, the NNT for aspirin in acute myocardial infarction is about 42, which is widely regarded as highly effective. An NNT of 67 is therefore quite favorable in the context of emergency medicine, particularly for a condition as serious as traumatic brain injury. Timing of Administration The CRASH-3 trial strongly reinforced the importance of administering TXA as early as possible after a head injury. The data indicated a 10% reduction in TXA’s effectiveness for every 20-minute delay in patients with mild to moderate head injury. This underscores the need for TXA to be administered in the pre-hospital setting, ideally by paramedics at the scene or en route to the hospital. Delaying treatment until after arrival at the emergency department or after conducting a CT scan may significantly reduce the drug's benefits. Implications for Clinical Practice The results of the CRASH-3 trial suggest that TXA should be considered for all patients with moderate traumatic brain injury, particularly those with a GCS of 9 to 15 and confirmed intracranial bleeding. For patients with severe head injuries (GCS of 8 or less, or with bilateral unreactive pupils), the benefits of TXA are less clear, likely due to the severity of the primary brain injury. Given the trial’s findings, it is recommended that TXA be integrated into clinical protocols for the management of head injuries. This is especially relevant in pre-hospital care, where early intervention is possible. TXA should be administered as soon as possible after the injury occurs, particularly in cases where a significant delay in getting to the hospital is expected. Cost-Effectiveness and Accessibility Another important aspect of TXA is its cost-effectiveness. In the UK, a 1-gram dose of TXA costs approximately £1, making it an affordable treatment option for healthcare systems worldwide. This low cost makes TXA a viable option not only in high-income countries but also in low- and middle-income countries where healthcare resources are often limited. Given its affordability and the potential to save lives, TXA is an attractive option for widespread use in managing traumatic brain injury globally. Considerations for Special Populations Although the CRASH-3 trial focused on adults, there is a strong rationale for extending its findings to pediatric patients. The physiology of traumatic brain injury in children is similar to that in adults, and there is no evidence to suggest that TXA would act differently in a younger population. As such, it would be reasonable to use TXA in children with TBI, following the same dosing guidelines adjusted for body weight. Future Directions: Intramuscular TXA and Beyond While CRASH-3 has provided valuable insights, research into TXA’s potential uses continues. One area of interest is the development of intramuscular (IM) TXA, which could be particularly useful in pre-hospital settings where intravenous (IV) access is challenging. The possibility of an auto-injector for TXA is also being explored, which could simplify administration and further broaden its use, especially in resource-limited settings. Conclusion: Implementing CRASH-3 Findings in Practice The CRASH-3 trial marks a significant advancement in our approach to treating traumatic brain injury. The evidence strongly supports the use of TXA, particularly in patients with moderate head injuries who receive the drug within three hours of injury. TXA is safe, cost-effective, and easy to administer, making it a valuable tool in both pre-hospital and hospital settings. The implementation of CRASH-3’s findings into clinical practice could save thousands of lives annually, particularly in settings where early intervention is possible. As the emergency medicine community, we must act swiftly to incorporate these findings into our protocols and training, ensuring that TXA is used effectively to improve outcomes for patients with traumatic brain injury worldwide.

Ep 147 - August 2019 Round Up
A Comprehensive Review of St Emlyn’s Blog: August 2019 Highlights Welcome to St Emlyn’s blog and podcast, where we reflect on the key topics and research from August 2019. In this review, we’ll explore the most impactful discussions and studies, providing valuable insights for emergency medicine professionals. From managing lower GI bleeding and addressing climate change in anaesthesia to examining PTSD in emergency services and the future of diagnostics, this post summarizes essential takeaways that are shaping our field. Managing Lower GI Bleeding in the Emergency Department One of the significant topics covered was the management of acute lower gastrointestinal (GI) bleeding, a common but challenging condition in the emergency department (ED). The complexity of managing these cases often lies in determining the correct priority of care, appropriate management strategies, and even the correct speciality for handling these patients. We reviewed a consensus guideline from the British Society of Gastroenterology and Hepatology, published in Gut, which offers practical recommendations for the diagnosis and management of acute lower GI bleeds. The guideline emphasizes the importance of using stratification tools to distinguish between stable and unstable patients, which can help streamline management in the ED. For stable patients, the Oakland score is recommended. This scoring system helps identify which patients can be safely managed on an outpatient basis, reducing unnecessary hospital admissions. Conversely, patients with a major bleed should be admitted and scheduled for a colonoscopy at the earliest opportunity. The guideline also highlights the value of CT angiography for hemodynamically unstable patients, a practice increasingly integrated into emergency care. Transfusion thresholds, set at 70 grams per litre, align with standard practices in other clinical settings, with adjustments for patients with cardiovascular disease. The guideline also recommends having dedicated GI bleed leads within trusts to ensure seamless coordination with emergency services. Sustainability and Climate Change in Anesthesia Another crucial discussion from August focused on the environmental impact of healthcare, particularly in anaesthesia. In the UK, healthcare is a significant contributor to climate change, driven by factors like travel, disposable materials, and the use of anaesthetic gases such as nitrous oxide and desflurane. A key paper by Cliff Shelton and colleagues underscores the need to adopt more sustainable practices in anaesthesia. For example, desflurane is approximately 3,000 times more potent as a greenhouse gas than carbon dioxide. The paper advocates for reducing the use of high-polluting gases and considering greener alternatives where possible. This shift towards sustainability in healthcare is essential, although challenging, given the nature of medical practice. However, small changes, such as reducing nitrous oxide use in departments where alternatives exist, can collectively make a significant difference. The paper serves as a call to action for healthcare professionals to be more mindful of their environmental impact and to seek sustainable solutions in their practices. Pre-Hospital Care: Comparing Macintosh and McGrath Laryngoscopes The debate over the best laryngoscope for pre-hospital rapid sequence intubation (RSI) is ongoing, and in August, we reviewed a study that contributed valuable data to this discussion. Published in Critical Care Medicine, the study compared the Macintosh and McGrath laryngoscopes in pre-hospital settings, involving 514 adult emergency patients. The study found that both devices were equally effective for pre-hospital RSI. Notably, it also revealed that switching to a different device after a failed intubation attempt was more successful than repeating the attempt with the same device. This finding aligns with the 30-second RSI drills many practitioners use, which advocate for changing the approach after a failed attempt. These findings have practical implications for both pre-hospital and in-hospital care. In the ED, switching to a video laryngoscope, such as the McGrath, after a failed intubation attempt could improve patient outcomes. As video laryngoscopes become more accessible in emergency departments, integrating them into RSI protocols could be a beneficial strategy. PTSD in Emergency Services: Rusty Carroll’s Series Rusty Carroll’s ongoing series on PTSD within the ambulance service continues to be one of the most impactful contributions to the St Emlyn’s blog. The August instalment focused on the aftermath of PTSD, exploring the journey towards understanding what “normal” looks like after such an experience. Rusty’s candid reflections resonate with many in the emergency services community, highlighting the mental health challenges prevalent in our field. The series has received positive feedback, with many readers finding comfort and validation in Rusty’s experiences. However, the widespread relatability of this series also underscores a concerning reality: many emergency service professionals are struggling with similar issues. As a community, we need to support one another, promote mental health awareness, and advocate for resources to address the psychological toll of our work. Revisiting Rusty’s previous installments in this series is highly recommended for a deeper understanding of the complex emotions associated with PTSD in emergency services. The Realities of Packed Red Cell Transfusions Another fascinating topic from August was the metabolic and biochemical characteristics of packed red cell transfusions, which have significant implications for trauma care in the ED. This discussion was sparked by a conversation on Twitter, leading to critical reflections on the assumptions we hold about blood transfusions. In trauma care, blood is often regarded as a superior alternative to crystalloids. However, the reality of what we’re transfusing—packed red cells—is quite different from whole blood. A study we reviewed highlighted some surprising statistics about the contents of packed red cells, including a pH of 6.79, a potassium level of 20, and a lactate level of 9.4. These figures reveal that packed red cells are far from the idealized image of whole blood. The metabolic implications of these characteristics are significant, particularly in the context of massive transfusions. For instance, packed red cells have low levels of 2,3-DPG, which affects their ability to release oxygen to tissues. This raises important questions about how we use blood in trauma resuscitation and whether our current practices are truly optimal. There’s also an ongoing pre-hospital trial in the UK, known as the RePHILL trial, which is examining the outcomes of patients randomized to receive either blood or no blood in pre-hospital settings. The results of this trial are eagerly anticipated and could challenge the assumption that blood is always better. This could lead to more nuanced transfusion practices in the future. The Future of Diagnostics: Insights from Rick Body Finally, we explored the future of diagnostics with insights from Rick Body. His presentation, originally given at the St Emlyn’s Live conference, offers a compelling vision of where diagnostics in the ED is heading. With the rise of machine learning, artificial intelligence (AI), and personalized diagnostics, the landscape of emergency medicine is rapidly evolving. These technologies are already being integrated into diagnostic processes, but they bring new challenges. The data generated by AI and machine learning can be complex, requiring a shift in how we interpret diagnostic results. We must move away from binary thinking and embrace a more nuanced understanding that includes probabilities, uncertainties, and complexities. As emergency medicine professionals, we need to prepare for this shift by engaging with these new technologies and incorporating them into our clinical practice. The future of diagnostics is exciting, but it will require ongoing education and adaptation to fully harness its potential. Conclusion August 2019 was a month rich with insightful discussions and important research that continue to influence our practice in emergency medicine. From managing lower GI bleeding and the environmental impact of anaesthesia to the complexities of blood transfusions and the future of diagnostics, these topics highlight the diverse challenges and opportunities we face in the ED. The St Emlyn’s blog and podcast aim to keep you informed and engaged with the latest developments in our field. This review has provided valuable insights that can be applied in your practice, helping you stay ahead in the ever-evolving landscape of emergency medicine. Stay tuned for more updates, and as always, feel free to share your thoughts and experiences with us. Until next time, take care and continue to push the boundaries of what’s possible in emergency medicine.

St Emlyn’s July 2019: Key Highlights Welcome back to St Emlyn’s, where we continue to share the latest insights, discussions, and advancements in emergency medicine. July 2019 was particularly rich in content, covering a wide range of topics from practical clinical advice to deeper reflections on the ethics and philosophy of emergency medicine. Here, we summarize the key points from the month’s posts, optimized for clarity and relevance. Upcoming Events: Resuscitology Course and MSc in Emergency Medicine Before diving into the content highlights, there are two important announcements: Resuscitology Course – December 2019 On December 14th, 2019, the Resuscitology course will be held in Manchester. This course, led by Cliff Reid, offers an in-depth exploration of why certain resuscitation techniques work and how they can be improved in high-stakes scenarios. This is a must-attend for anyone involved in emergency or critical care. Registration details are available on our blog. MSc in Emergency Medicine – 2019-2020 Cohort Recruitment is now open for the 2019-2020 cohort of the MSc in Emergency Medicine. This three-year online program, available to both doctors and nurses, offers an advanced curriculum in emergency medicine. Alumni like Janus Bae, Alan Grace, and Natalie May have found it immensely beneficial. By 2020, we hope to extend the program to paramedics as well, broadening its reach and impact. July 2019 Blog Highlights This month’s content ranged from clinical insights and research updates to philosophical discussions about the practice of emergency medicine. Disaster Medicine in Pakistan: Lessons Learned Zaf Kasim, now practicing in the United States, and Rashid Akhil from Pakistan collaborated on a blog post discussing the management of natural disasters, terrorist attacks, and major incidents in Pakistan. Zaf, who trained with us in Verchester, has become an authority in endovascular resuscitation, REBOA, and ECMO. This post sheds light on the expertise developed by medical professionals in Pakistan, particularly in response to large-scale disasters like the 2005 Kashmir earthquake. It’s a crucial read for anyone interested in global health or disaster medicine, as it demonstrates how effective disaster response systems can be developed even in resource-limited settings. Managing Major GI Hemorrhage: Practical Insights Chris Gray revisited a talk he gave at the St Emlyn’s Live Conference, focusing on the challenges of managing major gastrointestinal (GI) hemorrhage. Patients presenting with significant upper or lower GI bleeds pose unique challenges, particularly regarding airway management. Chris offers practical advice, emphasizing the importance of resuscitating before intubation and considering video laryngoscopy in difficult cases. The post also highlights the SALAD (Suction Assisted Laryngoscopy and Airway Decontamination) technique, which is particularly useful in managing patients with large amounts of gastric contents. Additionally, Chris touches on the use of PPIs, tranexamic acid (TXA), and terlipressin, although he advises caution until more evidence is available. The ongoing HALT-IT trial in the UK, investigating TXA in GI bleeds, is something to watch closely. Listeriosis: A Rare but Serious Infection Listeriosis, though uncommon, can have severe consequences, particularly for vulnerable populations like the elderly, pregnant women, newborns, and the immunocompromised. This blog post was prompted by a recent outbreak in the UK linked to contaminated hospital food. The post emphasizes the importance of considering listeriosis in differential diagnoses, particularly for patients presenting with unexplained gastrointestinal symptoms. Blood cultures are essential for diagnosis, making it important to include them in the workup for high-risk patients. Early diagnosis is key to improving outcomes in these cases. The Procedure Paradox: Ethical Reflections in Emergency Medicine “The Great Day Paradox” delves into the ethical and emotional challenges of emergency medicine. Inspired by a talk at the Don’t Forget the Bubbles conference, this post explores the contrast between the excitement clinicians feel during life-saving procedures and the often devastating impact these events have on patients. The post encourages clinicians to reflect on their motivations and maintain a patient-centered approach. Drawing on the teachings of John Hinds, it emphasizes that every procedure should be justified by both clinical need and appropriateness for the patient. This blog is a reminder of the importance of balancing clinical enthusiasm with compassion and ethical care. Inferior Vena Cava Filters in Major Trauma: An Evidence-Based Review Rich Carden reviewed the use of inferior vena cava (IVC) filters in major trauma patients, a topic that has been debated for years. IVC filters are intended to prevent pulmonary embolism (PE) in high-risk patients, such as those with significant lower limb or pelvic fractures. Rich discusses a recent randomized controlled trial published in the New England Journal of Medicine, which found that early prophylactic use of IVC filters did not reduce the incidence of symptomatic pulmonary embolism or death at 90 days. This finding suggests that IVC filters should not be used routinely in major trauma patients, though there may be specific cases where they are warranted. Psychological Performance in the Resus Room: Insights from Texas Ashley Leibig’s presentation at St Emlyn’s Live focused on psychological performance in the resus room, drawing on her experience with StarFlight in Texas. Her blog post explores key concepts such as human factors, crew resource management, and self-awareness in high-pressure situations. Ashley’s practical advice on managing oneself, the team, and the environment in emergency medicine is invaluable. This post is essential reading for anyone looking to improve their performance under pressure, whether in emergency medicine or other high-stress fields. The Resuscitative Care Unit: A New Model for Emergency Departments The concept of the resuscitative care unit (RCU) or ED-based critical care units was the focus of our final post of the month. Inspired by a paper published in the Emergency Medicine Journal (EMJ), this blog discusses the idea of creating RCUs to serve as a bridge between the emergency department and intensive care. RCUs are proposed as a solution for managing critically ill patients who require short-term intensive care but may not need full ICU admission. The post also references a JAMA study showing that ED-based ICUs can improve survival rates for critically ill patients. As emergency departments continue to evolve, integrating critical care capabilities is becoming increasingly important. Conclusion July 2019 was a month filled with rich, varied content at St Emlyn’s, offering practical advice, research updates, and philosophical reflections on emergency medicine.

Ep 141 - June 2019 Round Up
The Paradox of a Good Day in Emergency Medicine: Key Insights Emergency medicine is a field full of paradoxes, where the definition of a "good day" can differ starkly between healthcare professionals and their patients. This contradiction was a central theme in the discussions from June, which included reflections on the Don’t Forget the Bubbles (DFTB) conference, as well as key topics like the emotional toll of emergency medicine, the evolving nature of adolescent healthcare, and the importance of continuous learning. Don’t Forget the Bubbles Conference: A Valuable Resource for Pediatric Emergency Medicine The DFTB conference, held in London this year, has quickly become an essential event for those involved in pediatric emergency medicine. With a focus on both pediatric and adolescent healthcare, the conference offers invaluable insights and practical advice that can benefit even those who primarily work in adult emergency medicine. One of the standout topics from the conference was the Paradox of a Good Day in Emergency Medicine. This paradox arises from the nature of emergency medicine, where a "good day" for a clinician—filled with successful procedures and exciting cases—often coincides with what is likely the worst day of a patient’s life. This duality highlights the emotional and ethical complexities that emergency physicians must navigate. As practitioners advance in their careers, they often shift from focusing on the technical aspects of their work to becoming more aware of the profound impact these situations have on patients and their families. The Emotional and Psychological Impact of Emergency Medicine The emotional burden of emergency medicine was another significant theme at the DFTB conference, especially in sessions led by Kim Holt and Neil Spenceley. Holt, who has been involved in whistleblowing in the high-profile Baby P case, shared her experiences of dealing with criticism and professional challenges. Her story serves as a reminder of the resilience required to navigate the ethical and emotional complexities of healthcare. Spenceley’s session on doctors in distress emphasized the importance of creating supportive systems within healthcare departments. He argued that instead of focusing on making individuals more resilient, we should design systems that inherently support healthcare professionals. This shift in perspective is crucial in addressing the high levels of burnout and stress among emergency medicine practitioners. Laura Howard’s research on the psychological well-being of emergency physicians further explored this issue. Her qualitative study, which involved interviews with senior emergency physicians, revealed that the emotional impact of the job affects everyone, regardless of their experience level. Events like traumatic deaths, particularly those involving children or body disruptions, were identified as particularly distressing and had lasting effects on the practitioners involved. Howard’s work underscores the need for robust support systems to help clinicians manage the cumulative toll of their work. Bridging the Gap in Adolescent Medicine The DFTB conference also shed light on the often-overlooked area of adolescent healthcare. As healthcare providers, we tend to categorize patients as either adults or children, but adolescents require a tailored approach that addresses their unique needs. Russell Viner, a leader in pediatric healthcare, discussed how the concept of adolescence has evolved over time. In previous generations, adolescence was a brief period between puberty and adulthood, often marked by early milestones like starting a family. Today, however, adolescence is prolonged, with young people delaying traditional markers of adulthood due to social, educational, and economic factors. This shift has significant implications for how we approach healthcare for adolescents. In our practice, we must ensure that we are not only addressing the physical health of teenagers but also their mental and emotional well-being. This includes creating healthcare environments that are welcoming and appropriate for adolescents and offering resources that cater to their specific health concerns. Continuous Learning: Beyond ATLS and Traumatic Cardiac Arrest The importance of continuous learning and staying current with the latest research and best practices was another key message from June. Alan Grayson’s talk on going beyond ATLS (Advanced Trauma Life Support) was particularly impactful. While ATLS has been a cornerstone of trauma care globally, Grayson challenged us to think critically about its limitations, especially in high-income countries where multi-disciplinary teams are the norm. Grayson emphasized the need to focus on the basics—such as administering tranexamic acid, providing adequate analgesia, and ensuring timely administration of antibiotics—before diving into more advanced interventions like REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta). This back-to-basics approach serves as a crucial reminder that even in a high-tech medical environment, the fundamentals of care are what ultimately save lives. Jason Smith’s session on traumatic cardiac arrest offered new insights into how we approach this challenging situation. Traditional management has focused on chest compressions, adrenaline, and fluid resuscitation, but emerging evidence suggests that in cases of traumatic cardiac arrest, these interventions may not be as beneficial as once thought. Instead, giving blood and stopping the bleeding were identified as more critical interventions. However, Smith cautioned that this approach should be reserved for hypovolemic cardiac arrest, highlighting the importance of understanding the underlying cause of the arrest before determining the treatment course. The Reality of Intraosseous (IO) Blood Sampling A more technical but equally important topic discussed in June was the use of intraosseous (IO) blood sampling. For years, many clinicians have been taught that IO access can provide reliable blood samples for analysis. However, recent evidence suggests otherwise. A systematic review revealed that while it might be possible to obtain certain values like hemoglobin and sodium, the reliability of these results is questionable. Moreover, using IO samples for blood gas analysis or putting marrow through automatic analyzers can lead to equipment malfunction, a concern that has understandably caused anxiety among laboratory staff. Given this evidence, it’s clear that we need to rethink our approach to IO blood sampling. While it might still have a place in certain situations, particularly for microbiological cultures, relying on IO samples for comprehensive blood analysis is not advisable. This is another example of how continuous learning and critical evaluation of existing practices are essential for improving patient care and ensuring the best possible outcomes. Conclusion: Moving Forward with Insights from June As we reflect on the lessons from June, it’s evident that emergency medicine is a constantly evolving field that demands both continuous learning and emotional resilience. Whether through attending conferences like Don’t Forget the Bubbles, staying updated on the latest research, or addressing the psychological impact of our work, it’s clear that adaptation and mutual support are key to thriving in this challenging yet rewarding profession. At St Emlyn's, we are committed to fostering a culture of lifelong learning, open discussion, and mutual support. As we move into the second half of the year, let’s carry forward the insights we’ve gained, keep pushing the boundaries of our knowledge, and continue to support each other in the demanding yet rewarding field of emergency medicine. Take care, and keep up the incredible work you do.

Ep 139 - May 2019 Round Up
St. Emlyn's Podcast: Key Insights from May in Emergency Medicine As we transition into the warmer months, it's an opportune time to reflect on recent discussions and developments within the field of emergency medicine, particularly those highlighted in the latest episode of the St. Emlyn's podcast. This episode covered a wide range of topics, from workplace safety to advancements in pediatric care and innovative approaches in patient management. Below is a comprehensive summary of the key points discussed. Workplace Safety: A Pressing Concern The podcast began with a reflection on a recent violent incident at Newham Emergency Department (ED), which served as a stark reminder of the dangers healthcare professionals face daily. Emergency departments, by their very nature, are open and accessible, making them vulnerable to violent incidents. This recent attack has prompted a nationwide reassessment of safety measures, with many EDs enhancing their protocols to protect staff. The conversation emphasized that violence in the workplace should never be normalized. It’s crucial that healthcare professionals feel safe and supported in their working environment. Leadership within departments plays a critical role in this, not only by implementing robust safety protocols but also by fostering a culture of solidarity and mutual support among staff. The incident at Newham underscores the need for constant vigilance and proactive measures to ensure the safety of everyone working in emergency medicine. Leadership in Education: Simon Carley’s New Role In more positive news, Simon Carley’s recent appointment as the CPD (Continuing Professional Development) lead for the college was discussed. This role is a significant milestone, not just for Simon but also for the integration of modern educational approaches within formal medical education. Simon’s involvement with St. Emlyn's has long been focused on innovative, social media-driven education, and this new role offers an opportunity to bring these methods into a broader educational framework. The appointment highlights the value of combining traditional education with the dynamic, accessible formats offered by the #FOAMed (Free Open Access Meducation) community. It’s a recognition that medical education can benefit from new perspectives and that the integration of these ideas can enhance the learning experiences for healthcare professionals. Pediatric Status Epilepticus: Evaluating Second-Line Agents The discussion moved to a detailed analysis of pediatric status epilepticus, focusing on the findings from two key trials: the Eclipse trial and the ConSEPT trial. These studies compared the efficacy of levetiracetam (Keppra) and phenytoin as second-line agents for stopping seizures in children. The trials found no significant difference between the two drugs in terms of their effectiveness, which has led to debate within the medical community about whether to switch from phenytoin to levetiracetam. While levetiracetam is perceived as easier to administer and safer, the lack of a clear superiority has left the decision somewhat open. However, the ease of use and safety profile of levetiracetam make it an appealing option, and some institutions are considering making the switch. For clinicians, the takeaway is that while both drugs are viable options, the choice may ultimately come down to individual preferences and institutional protocols. The trials underscore the importance of continuous evaluation of treatment options, particularly in complex cases like pediatric seizures. Understanding Clinical Trials: The Importance of Statistical Literacy Simon Carley also highlighted the importance of understanding the statistical nuances in clinical trials, particularly the difference between demonstrating a difference between treatments and establishing their equivalence. This distinction is crucial for accurately interpreting research findings and making informed clinical decisions. The discussion emphasized that clinicians must be cautious in how they interpret trial results, particularly when it comes to determining whether treatments are genuinely equivalent or if the lack of a significant difference merely reflects the study’s design. This level of critical appraisal is essential for ensuring that new research is applied correctly in clinical practice. Prolonged Field Care in the ED: Learning from Military Medicine Another topic discussed was prolonged field care, a concept borrowed from military medicine that is becoming increasingly relevant in emergency departments due to overcrowding and delays. Rich Carden introduced the HITMAN mnemonic—Hygiene and Hydration, Infection, Tubes, Medication, Analgesia, and Nutrition—as a framework for managing patients who are stuck in the ED for extended periods. The HITMAN approach ensures that patients' fundamental needs are met even when resources are stretched. This method helps prevent complications and improves patient outcomes, even in less-than-ideal conditions. The approach is particularly relevant in today’s healthcare environment, where EDs are often overwhelmed and patients may wait longer than usual for admission or transfer. Atrial Fibrillation: Reassessing Cardioversion Strategies Atrial fibrillation (AF) management was another key topic. A recent study in the New England Journal of Medicine compared immediate cardioversion with a wait-and-see approach in patients with new-onset AF. The study found that a wait-and-see approach was non-inferior to immediate cardioversion, with 69% of patients in the wait-and-see group spontaneously cardioverting within 48 hours. This finding challenges the traditional approach of immediate cardioversion and suggests that in many cases, a more conservative approach may be just as effective. However, the decision should be made through shared decision-making with the patient, taking into account their preferences and the specific circumstances of their condition. This patient-centered approach ensures that treatment decisions are made collaboratively and with the patient’s best interests in mind. Traumatic Cardiac Arrest: Reevaluating Chest Compressions The podcast also touched on the evolving management of traumatic cardiac arrest, particularly the role of chest compressions. Recent studies, including one involving porcine models, suggest that in cases of hypovolemic traumatic cardiac arrest, chest compressions may not be beneficial and could even be harmful. Instead, the focus should be on addressing the underlying cause, such as restoring circulating volume. This shift in practice highlights the importance of understanding the specific etiology of cardiac arrest and tailoring resuscitation efforts accordingly. Communicating these changes to the entire resuscitation team is crucial, as there may be resistance to deviating from traditional protocols. Ensuring that everyone is on the same page and understands the rationale behind the approach is key to successful implementation. Virtual Reality in Pain Management: An Emerging Tool Virtual reality (VR) is emerging as a promising tool in pain management, particularly in pediatric patients undergoing painful procedures. A recent study discussed in the podcast found that children who used VR experienced less distress during procedures compared to those who received standard care. VR offers an innovative, accessible method for managing pain and anxiety, and its use is likely to expand in the coming years. The ability to create immersive environments that distract patients during procedures has the potential to improve patient experiences and outcomes, not just in children but potentially in adults as well. The Power of Peer Review: Enhancing Clinical Practice Finally, Simon Carley discussed the importance of peer review in clinical practice. Peer review is a valuable tool for continuous improvement, allowing clinicians to receive feedback from colleagues on their performance. While it can be challenging to create a culture where feedback is welcomed and constructive, the benefits are significant. Peer review helps clinicians avoid complacency, stay up-to-date with best practices, and continually refine their skills. It’s a simple, cost-effective way to ensure that healthcare professionals are delivering the highest standard of care. Creating a supportive environment where feedback is seen as an opportunity for growth rather than criticism is essential for the success of peer review initiatives. Conclusion The discussions in this month’s St. Emlyn's podcast highlight the complexities and challenges of working in emergency medicine, from ensuring workplace safety to staying current with evolving practices. By engaging with new research, embracing innovative tools like virtual reality, and fostering a culture of continuous improvement through peer review, we can continue to advance the field and improve patient care. As always, the St. Emlyn's blog and podcast remain valuable resources for staying informed and connected with the latest developments in emergency medicine.

Ep 138 - Traumatic Cardiac Arrest with Prof Jason Smith RN
The Evolution of Traumatic Cardiac Arrest Management: Military Insights and Civilian Applications Traumatic cardiac arrest (TCA) is a critical and often fatal condition encountered in both military and civilian emergency medicine. Historically, the prognosis for patients with TCA has been poor, leading many to believe that resuscitation efforts are largely futile. However, recent developments, particularly those arising from military experience, are challenging this perspective. In this post, we explore insights shared by Dr. Jason Smith, a consultant in emergency medicine and a seasoned military doctor, about the evolving understanding of TCA, including the role of chest compressions and the application of military practices in civilian settings. Traumatic Cardiac Arrest: Insights from Military Experience TCA is relatively rare in civilian settings, with major trauma centres like Plymouth seeing a case every one to two months. However, in military environments, where high-velocity injuries are more common, TCA occurs more frequently. Dr. Jason Smith’s experience in Afghanistan revealed that traumatic cardiac arrests happened as often as three to four times a week. This stark contrast has driven the development of specific management protocols in military settings, where hemorrhagic shock is the leading cause of TCA. In these high-intensity environments, the focus is on immediate and aggressive interventions. These protocols, developed on the battlefield, have significantly improved outcomes and are now being adapted for civilian trauma centres, where they continue to challenge the longstanding belief that TCA is nearly always fatal. From the Battlefield to the Emergency Room: Evolving TCA Management Over the past decade, the management of TCA has undergone significant evolution, largely influenced by military practices. Dr. Smith’s team in Afghanistan developed a "bundle of care" designed to rapidly and effectively address the key factors leading to TCA. This bundle includes: External Hemorrhage Control involves ensuring that tourniquets are properly applied and functioning, alongside other measures to control external bleeding. Oxygenation and Ventilation: Rapid intubation and ventilation to maintain oxygen delivery to vital organs. Bilateral Thoracostomies: Decompressing the chest on both sides to manage potential tension pneumothorax. Rapid Volume Replacement: Administer warm blood and blood products intravenously or intraosseously to quickly replace lost volume. Pelvic Binding: Applying a pelvic binder in cases of blunt trauma to reduce pelvic volume and control bleeding. Consideration of Thoracotomy: In specific cases, such as penetrating trauma to the chest, thoracotomy is considered as a life-saving intervention. This structured approach, honed in military contexts, has led to outcomes that are significantly better than those reported in civilian literature at the time. These practices are now being adapted for civilian use, where they are helping to improve survival rates for TCA patients. Challenging Old Assumptions: New Data on TCA Survival One of the most significant shifts in the perception of TCA has come from recent data showing that survival rates are not as dismal as previously thought. In military populations from Iraq and Afghanistan, survival rates from TCA have been reported at around 10.6%. Even more compelling is data from the UK’s TARN database, which indicates a 7.5% survival rate for civilian TCA cases, including those caused by blunt trauma. These figures are comparable to survival rates for non-traumatic cardiac arrest, leading to a reassessment of TCA management. The traditional view that resuscitation in TCA is futile is increasingly being challenged by evidence that with the right interventions, survival is possible. The Controversy Around Chest Compressions in TCA One of the most hotly debated topics in TCA management is the role of closed chest compressions. In standard Advanced Life Support (ALS) protocols, chest compressions are a fundamental part of resuscitation. However, in the context of TCA, particularly hemorrhagic TCA, their effectiveness has been called into question. Dr. Smith’s research has played a pivotal role in this debate. He observed that during resuscitation in Afghanistan, the use of a Belmont rapid infuser often resulted in alarms indicating that chest compressions were creating too much pressure inside the thorax, preventing effective blood transfusion. This led to the hypothesis that chest compressions might be not only ineffective but potentially harmful in hemorrhagic TCA. To explore this hypothesis, Dr. Smith and his colleagues at DSTL Porton Down developed an animal model using swine to simulate TCA. The study aimed to replicate the conditions seen in hemorrhagic TCA by bleeding the animals to a mean arterial pressure (MAP) of 20 mmHg. The animals were then divided into groups to compare the outcomes of different resuscitation strategies, including chest compressions alone, blood transfusion alone, and combinations of the two. Key Findings: Prioritizing Blood Over Compressions The study’s results were revealing. Animals that received blood transfusions without chest compressions had significantly better outcomes than those that received chest compressions alone or in combination with blood transfusion. Specifically, all animals that received only chest compressions were dead by the end of the study, while those that received blood alone showed signs of return of spontaneous circulation (ROSC). Moreover, when chest compressions were combined with blood transfusion, the results were mixed. While some animals achieved partial ROSC, the overall survival was lower than in the group that received blood alone. This led to the conclusion that in hemorrhagic TCA, chest compressions might be not only unnecessary but potentially detrimental. These findings, while based on animal models, have significant implications for clinical practice. They suggest that in cases where haemorrhage is the primary cause of TCA, the focus should be on rapid volume replacement with blood and blood products rather than on chest compressions. Translating Research into Practice While Dr. Smith’s study provides compelling evidence, applying these findings to human practice requires careful consideration. The study’s limitations, including its reliance on animal models and the specific conditions of hemorrhagic TCA, mean that more research is needed to fully understand how these findings apply to diverse patient populations. However, the study does provide a strong foundation for re-evaluating current protocols. In situations where haemorrhage is identified as the primary cause of TCA, emergency teams might consider prioritizing volume replacement over chest compressions, especially in environments where rapid blood transfusion is possible. The challenge, as Dr. Smith noted, lies in training and protocol development. Chest compressions are deeply ingrained in resuscitation practice, and changing this mindset requires robust training and clear guidelines. Emergency departments and trauma centres need to prepare their teams for scenarios where the traditional approach might not be the best one, ensuring that all members are aligned in their approach to TCA management. Conclusion: A New Paradigm for Traumatic Cardiac Arrest The management of traumatic cardiac arrest is evolving, driven by insights from military medicine and supported by emerging data from civilian practice. While challenges remain, particularly in shifting entrenched practices around chest compressions, the future of TCA management looks promising. Survival rates once thought to be negligible, are improving as we better understand the mechanisms at play and refine our interventions accordingly. For emergency medicine practitioners, staying informed about these developments is crucial. As more data becomes available and as we continue to learn from both military and civilian experiences, the protocols for TCA will undoubtedly continue to evolve. The days of viewing traumatic cardiac arrest as a futile scenario are fading. With the right approach, training, and tools, we can offer these patients a fighting chance at survival. In summary, putting science into the argument has been a game-changer, and continuing to blend evidence with practice will be key to improving outcomes in this challenging area of emergency medicine.

Ep 136 - Wellbeing for the broken with Liz Crowe
Navigating a Mental Health Crisis in Healthcare: A Guide to Recovery Healthcare professionals, particularly those working in critical care and emergency medicine, often face intense situations that test their emotional and mental resilience. While most of the time, we manage to cope with the challenges, there are rare moments that catch us completely off guard, leaving us feeling utterly broken. This guide explores what to do when work breaks you—a situation that is seldom discussed but is profoundly important. Understanding the Crisis Point It's crucial to distinguish between the routine stressors of healthcare work and a true mental health crisis. The latter is not just a rough day or a series of challenging weeks. Instead, it's a once-in-a-career event that completely shakes your confidence and leaves you questioning your ability to continue in your role. These moments can be triggered by traumatic patient cases, critical errors, or cumulative stress that finally overwhelms you. When such a crisis occurs, it’s important to recognize that what you're experiencing goes beyond normal stress—it’s a mental health crisis. Symptoms may include tremors, uncontrollable crying, sleeplessness, and a sense of detachment. These are signs that your mental health is under severe strain, and they should be taken seriously. Preparing for a Crisis Before It Happens One of the most valuable steps you can take is to prepare for the possibility of a mental health crisis before it happens. Just as we plan for emergencies in our professional roles, we should also have a plan in place for our mental well-being. 1. Build a Support Network: Identify a few trusted individuals—whether colleagues, friends, or family—who can be your go-to support in times of crisis. Share with them the kinds of situations that might overwhelm you and how they can help if the time comes. 2. Establish a Routine: Develop a daily routine that includes exercise, healthy eating, and regular sleep. Routine can serve as a stabilizing force during a crisis, providing a sense of normalcy when everything else feels chaotic. 3. Seek Professional Help: It’s wise to establish a relationship with a therapist or counsellor before a crisis hits so you have someone to turn to when you need it. If therapy isn’t an option, know how to access support through your GP or other services. 4. Practice Self-Care: Identify activities that help you relax and de-stress. Whether it’s meditation, reading, or spending time with loved ones, incorporate these into your routine. These activities can become particularly crucial during a crisis. What to Do During a Crisis When you find yourself in the midst of a mental health crisis, your judgment may be impaired, making it difficult to make decisions or know what to do next. Here’s how to navigate those critical moments: 1. Reach Out for Support: Even though your instinct may be to withdraw, it’s essential to reach out to someone in your support network. Connection is key to navigating a crisis. Tell them what’s happened and how you’re feeling, even if it feels incredibly difficult to do so. 2. Stick to Your Routine: Maintain your daily routine as much as possible, even if it feels challenging. Simple actions like getting up at the same time, eating regular meals, and exercising can help you regain a sense of control. 3. Avoid Self-Medication: The temptation to numb your feelings with alcohol, drugs, or other substances can be strong during a crisis. However, these can exacerbate the situation. If you feel the need for medication, consult with a healthcare professional instead of self-medicating. 4. Seek Professional Help: If you’re struggling to cope, don’t hesitate to seek professional assistance. Talking to a professional, whether through your GP, a therapist, or a crisis hotline, can provide the validation and support you need. The Path to Recovery Once the immediate crisis has passed, the journey to recovery begins. This process is often slow and requires patience, self-compassion, and continued support. 1. Allow Yourself Time: Recovery from a work-related mental health crisis takes time, often longer than expected. Be patient with yourself and understand that healing is a gradual process that may take months or even years. 2. Maintain Your Routine: Continue the routine that helped you during the crisis. Regular exercise, healthy eating, and sufficient sleep are the foundations of good mental health and will support your recovery. 3. Reconnect with Your Purpose: Reflect on why you chose your profession and what you love about your job. Reconnecting with these motivations can help you find meaning and purpose again, even after a traumatic experience. 4. Set Small Goals: During your recovery, set small, achievable goals rather than overwhelming yourself with big plans. Celebrate small victories, whether it’s getting through a day at work, completing a project, or simply feeling a bit better. 5. Practice Self-Compassion: Treat yourself with the same compassion you would offer a friend or colleague going through a similar situation. Acknowledge your progress, and don’t be too hard on yourself if recovery takes longer than expected. Dealing with Shame and Guilt One of the most challenging aspects of recovery is dealing with feelings of shame and guilt, which can be powerful and difficult to overcome. 1. Acknowledge Your Feelings: It’s normal to feel shame and guilt after a traumatic event, but also understand that these feelings are often irrational and not based on reality. 2. Challenge Negative Thoughts: When feelings of shame or guilt arise, challenge them by asking yourself if they are truly justified. Often, these feelings are rooted in distorted thinking patterns that can be corrected. 3. Talk About It: Sharing your feelings with someone you trust can help alleviate the burden of shame and guilt. Expressing these emotions can reduce their power over you and facilitate healing. 4. Focus on the Positive: Remind yourself of all the good you’ve done in your career. Think about the lives you’ve touched and the positive impact you’ve had. Your career is more than just one event; it’s a series of contributions that define your professional journey. Moving Forward At St. Emlyn’s, we believe that your narrative as a healthcare professional is not defined by a single event. You are more than the challenges you’ve faced, and you have the strength to overcome even the most difficult moments. Remember that you are part of a community that understands what you’re going through and is here to support you. 1. Stay Connected: Don’t let the crisis isolate you. Stay connected with your colleagues, friends, and family, who can provide support, perspective, and encouragement as you move forward. 2.

Ep 135 - April 2019 Round Up
St. Emlyn's April 2019 Podcast Highlights Hello and welcome to the St. Emlyn's blog. I'm Simon Carley, and today I'll be sharing the exciting developments from April 2019 on our St. Emlyn's blog. This month has been packed with insightful posts and groundbreaking research, so let's dive in. Andromeda Shock Trial: A New Perspective We begin with a thought-provoking journal club post by Dan Horner, an intensivist and emergency physician, who explores the Andromeda Shock trial. This study, conducted in Argentina, compared two resuscitation strategies for patients with septic shock: targeting lactate levels versus peripheral perfusion as measured by capillary refill time. The Andromeda Shock trial is fascinating because it challenges our reliance on measurable indicators like lactate levels. Many experts argue that lactate doesn't provide the information we think it does about sepsis. Rich Carden's excellent blog on lactate delves into this topic, explaining why the common assumption that lactate indicates anaerobic metabolism is incorrect. Insights from leading intensivists like John Mayberg and Simon Finfer prompt a reevaluation of how we interpret lactate levels. In the trial, patients managed using peripheral perfusion monitoring showed better outcomes than those managed by lactate levels. Although the trial is underpowered to show definitive differences, the findings suggest that both methods are likely similar in effectiveness. This study highlights the need to reconsider our approach to monitoring septic shock patients and suggests that capillary refill time could be a valuable, low-cost alternative to lactate measurement. Enhancing Learning with Minimal Effort Next, we turn to an intriguing blog by Nick Smith, who shares a lazy yet effective way to enhance learning. Inspired by Matthew Walker's book "Why We Sleep," Nick discusses the critical role of rest in learning and retention. The key takeaway is simple: if you're not well-rested before and after learning, you won't retain information effectively. Nick emphasizes understanding individual learning rhythms. Some people, like early risers, learn best in the morning, while night owls perform better later in the day. This insight is crucial for medical educators and learners alike. For instance, teenagers naturally have later sleep cycles, making early morning learning sessions less effective. Walker’s book provides compelling evidence on how sleep affects cognitive function and memory consolidation. During sleep, particularly REM sleep, the brain processes and organizes information learned throughout the day. Lack of sleep disrupts this process, leading to poorer retention and understanding. Nick integrates these scientific insights with practical advice, making his blog an invaluable resource for optimizing learning strategies. He offers tips on improving sleep hygiene, such as maintaining a consistent sleep schedule, creating a restful environment, and avoiding stimulants before bedtime. Nick also highlights the impact of disrupted sleep patterns, especially when attending international conferences. Jet lag and lack of sleep can severely hamper your ability to absorb new information. Moreover, alcohol consumption negatively affects learning, which is worth considering during conference social events. Nick's post is packed with practical tips and impressive infographics that make the information easily digestible. It's a must-read for anyone involved in medical education or looking to optimize their learning strategies. Aortic Emergencies: Key Insights from George Willis George Willis, a renowned speaker and former professional American football player, presented on aortic emergencies at the St. Emlyn's Live Conference. His talk is a goldmine of information for emergency medicine practitioners. Aortic emergencies, such as ruptured aortic aneurysms and dissections, are critical conditions that require swift diagnosis and management. George emphasizes using clinical history and tools like ultrasound to diagnose aortic emergencies. For example, ultrasound can identify abdominal aortic aneurysms and dissections via transthoracic echo. He also discusses managing these patients, particularly those with dissections, who present unique challenges due to their unstable blood pressure. One notable case George describes involves managing pericardial effusion and tamponade resulting from aortic dissection. Techniques like pericardiocentesis can be life-saving, buying valuable time for definitive treatment. George's practical tips and real-world examples make his presentation an invaluable resource for anyone dealing with aortic emergencies. Managing aortic emergencies requires a nuanced approach, particularly when dealing with unstable patients. George discusses using medications like labetalol for beta-blockade and alpha-blockade to manage blood pressure in dissection patients. These medications help reduce the strain on the aorta without compromising patient safety. George also covers using imaging techniques, such as CT angiography, to confirm diagnoses and plan interventions. The ability to quickly and accurately diagnose these conditions is crucial for timely surgical intervention, which can significantly improve patient outcomes. Ambulatory Care for PEs: Dan Horner's Expert Insights Dan Horner returns with another insightful blog, this time on the ambulatory management of pulmonary embolisms (PEs). At the Arkham conference in Belfast, Dan discussed the benefits and challenges of treating PEs as outpatients. His post is a comprehensive guide to identifying which patients can be safely managed at home and which require hospital admission. Dan explores various prognostic factors and scoring systems, such as PESI and sPESI, used to predict complications in PE patients. While these scores are better than Gestalt, they are not without limitations. Dan also touches on biomarkers and their role in predicting PE outcomes, though current data is not definitive. Identifying patients who can be safely managed on an outpatient basis is crucial for optimizing resource use and improving patient comfort. Dan discusses the criteria for outpatient management, including the absence of hemodynamic instability, low bleeding risk, and adequate home support. These criteria help ensure that only patients with a low risk of complications are selected for ambulatory care. Treatment options for PEs are evolving, with a shift from traditional anticoagulants like Warfarin to NOACs/DOACs. While these newer agents offer convenience, the evidence base is still developing. Dan also addresses the complexities of managing PEs in special populations, such as pregnant patients, highlighting the need for individualized care and informed discussions with patients. Implementing ambulatory care for PEs requires careful planning and coordination. Dan provides practical advice on setting up ambulatory care pathways, including patient education, follow-up protocols, and the use of telemedicine to monitor patients remotely. He also discusses the importance of multidisciplinary collaboration in managing these patients. Dan's blog is a treasure trove of resources, including guidelines for outpatient management, risk scores, and follow-up strategies. It's an essential read for anyone involved in the care of PE patients, offering the latest evidence and practical advice.
