In the most recent BroomeDocs podcast, we talk about an attempt to use the IM route to give cardiac arrest victims epinephrine faster. (The podcast and Research Roundups blog post might actually come out next week.) I was skeptical about the outcomes, partly because the evidence that epinephrine helps at all in cardiac arrest is rather shaky. However, if you really want to give epinephrine quickly, it seems like the intraosseous route is the better way to do that during an arrest.
