Ep 89 - IM Epi in OHCA, Part II

The EMS Lighthouse Project

Back in episode 80 we discussed a feasibility study out of Salt Lake City that showed IM epi resulted in 3-minute faster administration in cardiac arrest. It was underpowered to show survival, however. Fortunately, the great folks in Salt Lake City is back with a larger bite at the statistical apple. Dr Jarvis discusses the background around what we know about epinephrine in cardiac arrest (briefly, for once), walks us through this new study, and puts it in context of modern clinical practice.
