EMCrit Podcast 6 – Push-Dose Pressors
Note: Please listen to the PDP update episode either before or immediately after listening to this one Finally a non-intubation topic! Bolus dose pressors and inotropes have been used by the anesthesiologists for decades, but they have not penetrated into standard emergency medicine practice. I don’t know why. They are the perfect solution to short-lived hypotension, e.g. post-intubation or during sedation. They also can act as a bridge to drip pressors while they are being mixed or while a central line is being placed. Click Here for printable sheet with mixing instructions Epinephrine Do not give cardiac arrest doses (1 mg) to patients with a pulse Has alpha and beta-1/2 effects so it is an inopressor Onset-1 minute Duration-5-10 minutes Mixing Instructions: Take a 10 ml syringe with 9 ml of normal saline Into this syringe, draw up 1 ml of epinephrine from the cardiac amp (amp contains Epinephrine 100 mcg/ml) Now you have 10 mls of Epinephrine 10 mcg/ml Dose: 0.5-2 ml every 1-5 minutes (5-20 mcg) No extravasation worries! Mixing Video: Phenylephrine Phenyl as a bolus dose is clean, quick, and never causes trouble. But... It is pure alpha, so no intrinsic inotropy; it may increase coronary perfusion which can improve cardiac output. I only use this in tachycardic patients (and even then, only sometimes) Onset-1 minute Duration- 5-10 minutes (usually 5) Mixing Instructions: Take a syringe and draw up 1 ml of phenylephrine from the vial (vial concentration must be 10 mg/ml) Inject this into a 100 ml bag of NS Now you have 100 mls of phenylephrine 100 mcg/ml Draw up some into a syringe; each ml in the syringe is 100 mcg Dose: 0.5-2 ml every 1-5 minutes (50-200 mcg) No extravasation worries! Mixing Video: Ephedrine I don’t use this one, listen to the podcast to hear why. I put it here solely for the anesthesiologists on the blog. Onset-Near Instant Duration-1 hour Mixing Instructions: Take a 10 ml syringe with 9 ml of normal saline Into this syringe, draw up 1 ml of ephedrine from the vial (vial contains Ephedrine 50 mg/ml) Now you have 10 mls of Ephedrine 5 mg/ml Dose: 1-2 ml every 2-5 minutes (5-10 mg) No extravasation worries! Additional Video of a Real Patient By Larry Mellick's Crew Update: This study compares push-dose phenylephrine to continuous infusion--no difference between the two (Anesthesia Analgesia 21012;115(6):1343) First article in the ED demonstrates efficacy on blood pressure (The Journal of Emergency Medicine Volume 49, Issue 4, October 2015, Pages 488–494) Here is a review article from the nursing literature Now on to the Podcast...

EMCrit Podcast 1 – Sympathetic Crashing Acute Pulmonary Edema (SCAPE)
Here it is, the 1st EMCrit podcast. It's on the topic of Sympathetic Crashing Acute Pulmonary Edema (SCAPE). This condition is on a very different part of the disease spectrum from FOPE (Fluid-Overload Pulmonary Edema, an acronum I first saw used by by @Cameronks) To boil it down to 10 seconds: Start patient on Non-invasive ventilation with a PEEP of 6-8; quickly titrate to a PEEP of 10-12. Start the patient on a nitroglycerin drip. Administer a loading dose of 4oo mcg/min for 2 minutes (120 ml/hour on the pump for 2 minutes with the standard nitro concentration of 200 mcg/ml.) Then drop the dose to 100 mcg/min and titrate it up from there as needed. By 10 minutes, your patient should be out of the water. See crashingpatient.com for the references. Here is some info from a handout from a lecture I gave on the topic: High Dose Nitroglycerin Homeopathic nitroglycerin does not work so well Start at 50-100 mcg/min, you can rapidly titrate to 200-400 mcg/min. You must stand at the bedside to use these doses. Need >120 mcg/min to get sig decreased Pulm Cap Wedge Pressure (Am J Cardio 2004;93:237) But even this strategy is not as effective as the … Nitro Bolus First Can give 400-800 mcg over 1-2 minutes = 400 mcg/min for 1-2 minutes. (Annals EM 1997, 30:382) How to do it Standard nitro mix is 200 mcg/ml. VERIFY YOUR HOSPITAL’S MIX BEFORE USING THESE RECS In order to give the 400 mcg/min for 2 minutes, set the pump to Rate: 120 cc/hr Volume to be Infused: 4 ml (This will deliver 400 mcg/min for 2 minutes and then stop) Or Draw up 4 ml of the nitro and 6 ml of NS and give over 2 minutes After the bolus, I drop the drip to 100 mcg/min and titrate up from there to effect When the patient gets better, you need to sharply decrease this drip rate Some folks have gone even further High dose nitroglycerin for severe decompensated heart failure—2 mg at a time (Ann Emerg Med 2007;50:144) Cotter gave isosorbide 3 mg q 5 minutes with good results in his study. This is equivalent to nitro 600 mcg/min. (Lancet 1998 351:9100, 389-393) Bolus intravenous nitroglycerin predominantly reduces afterload in patients with excessive arterial elastance (Journal of the American College of Cardiology Volume 22, Issue 1, July 1993, Pages 251–257) Update Piyush Mallick did an amazing study on nitro-bolus to avert intubation Someone finally put the term into the literature (Agrawal N, Kumar A, Aggarwal P, Jamshed N. Sympathetic crashing acute pulmonary edema. Indian J Crit Care Med 2016;20:719-23) 1-2 mg bolus doses are safe and effective (American Journal of Emergency Medicine 2017, 35 (1): 126-131) How you set-up the drip sig. affects time to med (Douma MJ, O'Dochartaigh D, Corry A, et al How intravenous nitroglycerine transit time from bag-to-bloodstream can be affected by infusion technique: a simulation study Emerg Med J 2015;32:498-500.)
