Description:  Let’s say you were looking for a safe and effective BLS option for analgesia. Something other than oral acetaminophen or ibuprofen. You want the Green Whistle (methoxyflourane) but you can’t get the Green Whistle (thanks FDA!). How about sub-dissociative ketamine by nebulizer? Sounds great, but you’re worried about your colleagues getting stoned, aren’t you? Admit it, you are. Fortunately, there are breath actuated nebulizers. Maybe those things will work?   Dr Jarvis reviews a recent paper that compares the effectiveness of nebulized ketamine compared with IV ketamine. And he gives a quick review of some other papers that paved the way for this one.   Citations: 1.

Nebulized Ketamine?

What value does EtCO2 have when it comes to predicting survival from cardiac arrest? We all know a sharp spike in EtCO2 is associated with ROSC, but what about persistently elevated levels? What does this mean for decision making when it comes to termination of resuscitation?   Join Drs. Jeff Jarvis, Remle Crowe, and Heidi Abraham for the first episode of “Between Two Nerds”, a subgenre of the EMS Lighthouse Project podcast suggested in episode 82 by Dr. CJ Winckler, as they run through a new paper that may shed some light on this question.   Citation: 1.

Ep 83 - EtCO2 in Cardiac Arrest

The debate about which drug to use for sedation prior to RSI will.. just.. not… die. Advocates for both ketamine and etomidate approach the argument with near-religious zeal. There have been studies. We’ve even covered some here. What we need is a systematic review and meta-analysis, preferably using a type of analysis that recognizes that this likely isn’t a black and white question and can bring some.. .nuance to it. That’s were our friend Bayes comes in. Dr. Jarvis is joined by Drs Remle Crowe and CJ Winkler to discuss this paper and what in the hell Bayesian analysis actually is. We get some nice book recommendations in the process. Plus, we check in with ChatGPT for answers. Oh, BTW... don't take zoological advice from Dr. Winkler. Contrary to his thoughts, Giraffe's do NOT, in fact, have larger hearts than elephants.  Citations:

Ketamine v Etomidate for RSI: A Bayesian Meta-Analysis

Atrial Fibrillation with rapid ventricular response is a common cause of EMS activations and ED visits. It is associated with chest discomfort, palpitations, and hypotension. Treatment is aimed at either rhythm control or rate control with rate control being the most common first line approach. EMS has the potential to treat this condition with medications such as diltiazem, metoprolol, or amiodarone. For those patients with hemodynamic instability, EMS can provide synchronized cardioversion. The question for this podcast, however, is does it matter if EMS treats A Fib or not. Dr. Jarvis recorded this episode in front of a live audience at the State of Jefferson conference in beautiful Ashland, Oregon with Mike Verkest, and special guest Dr Maia Dorsett.    Citation: Fornage LB, O’Neil C, Dowker SR, Wanta ER, Lewis RS, Brown LH: Prehospital Intervention Improves Outcomes for Patients Presenting in Atrial Fibrillation with Rapid Ventricular Response.

Treatment of Atrial Fib with RVR

Dr. Jarvis is joined by OG co-host Mike Verkest and Dr. Brent Myers from NAEMSP 2024. We talk about an intriguing concept in cardiac arrest… giving the initial dose of epinephrine IM instead of starting an IV or IO. They discuss a 2021 paper that compared this approach to standard dosing in a feasibility study done in Salt Lake City. Those authors released some additional data from this study… this time about survival. We talk about the potential ramifications.
