    Ep 103 - Preeclampsia, Eclampsia, and Postpartum Hemorrhage

    ACOG, the American College of Obstetricians and Gynecologists, recently published EMS guidelines for treatment of hypertension in pregnancy/pre-eclampsia, eclampsia, and postpartum hemorrhage. Drs. Jenna White and Christopher Zahn join Dr Jarvis to discuss the science behind these recommendations as well as how to implement them into our practice.  Citations: 1. https://www.acog.org/programs/obstetric-emergencies-in-nonobstetric-settings 2.

    Ep 102 - Ketamine for Agitation with Dr Crowe

    You use ketamine. I use ketamine. We all use ketamine. But… how safe it is, really? A new study out of Toronto suggests 30% of patients who receive ketamine have adverse events, a rate higher than seen in the ED. What are we to make of this? I bring Dr Remle Crowe on to discuss… Citations: 1.     Kwong JL, Verbeek PR, Leong YC, Turner L, Huiskamp M, Drennan IR, Francom S, Ropp S, Cheskes S: Paramedic use of ketamine for severe agitation and violence.

    Ep 101 - PreOxygenation and Why Words Matter

    We've covered pre-oxygenation strategies and intubation alot on this podcast, mayber more than anyting else. We covered the definition of FPS in E74, the DEVICE trial on DL vs VL in E75, and the PREOXI trial of NIV vs Mask Pre-oxygenation in E86. Now we have another Preoxygenation paper, this one that reports no difference between preoxygenation with BVM and face mask. WTAF? Better listen, because it turns out words matter, definitions are... definitional, and we absolutely MUST read more than just the abstract.   Citations: 1.     Gottlieb M, Alexander R, Love AK: Comparison of Preoxygenation Strategies for Intubation of Critically Ill Patients.

    Ep 100 - Amio v Lido in OHCA w Tanner Smida

    The 2017 NEJM study, ALPS, compared amiodarone, lidocaine, and placebo for refractory shockable rhythms in adults with out of hospital cardiac arrest. They found no significant difference in survival to hospital discharge or functional survival between any of the arms. If that study has left you confused, you’re not alone.  And you’re in luck. Tanner Smida joins us again to discuss his latest paper using something called target trial emulation to assess the difference in ROSC and survival to discharge between amiodarone and lidocaine. This is a great discussion of his paper, the methodology, and how we can put his results into the context of ALPS.

    Ep 99 - Adenosine or Diltiazem for SVT?

    We just got a new paper that compares initial treatment with adenosine compared with diltiazem for the treatment of adults with SVT in the ED. Wouldn’t it be great if it turned out that diltiazem was just as effective, if not more effective, as adenosine without the crappy feeling?  Yeah, that’d be great, but what do we do with statistically insignificant results. Is there, perhaps, a way to save this “insignificant” paper? Fear not, Bayes is here!  Yes, that’s right, Dr. Jarvis is grabbing this new paper and diving straight back into that deep dark rabbit hole of Bayesian analysis.  Citation: 1.     Lee CA, Morrissey B, Chao K, Healy J, Ku K, Khan M, Kinteh E, Shedd A, Garrett J, Chou EH: Adenosine Versus Fixed-Dose Intravenous Bolus Diltiazem on Reversing Supraventricular Tachycardia in The Emergency Department: A Multi-Center Cohort Study.

    Ep 98 - Does the Sequence of RSI Medications Matter

    The next time you go to intubate a patient, should you give the sedation before the paralytic or the paralytic before the sedative? Does it matter? And what the hell does Bayes have to do with any of this? Dr Jarvis reviews a paper that uses Bayesian statistics to calculate the association between drug sequence and first attempt failure. Then he returns to Nerd Valley to talk about how to interpret 95% confidence intervals derived from frequentists statistics compared to 95% credible intervals that come from Bayesian statistics.  Citations: 1.     Catoire P, Driver B, Prekker ME, Freund Y: Effect of administration sequence of induction agents on first‐attempt failure during emergency intubation: A Bayesian analysis of a prospective cohort.

    E97 - Bayes and Calcium Before Diltiazem in Atrial Fibrillation

    We covered a paper in episode 81 that suggested treating atrial fibrillation with rapid ventricular response in the field could lower mortality. But it also drops BP a bit. Could pretreating these patients with calcium lower the risk of hypotension? Dr Jarvis puts on his nerd hat and uses Bayesian analysis to assess a new randomized, placebo-controlled study that looked at just this thing. Why is he going off on this Bayes thing? Because he’s been reading a couple of book on it and wanted to take it for a spin.    Tables:     Charts:   Bayesian Distributions:   Citation:   1.     Az A, Sogut O, Dogan Y, Akdemir T, Ergenc H, Umit TB, Celik AF, Armagan BN, Bilici E, Cakmak S: Reducing diltiazem-related hypotension in atrial fibrillation: Role of pretreatment intravenous calcium.
