    Epinephrine for Non-Shockable In-hospital Cardiac Arrest—Time is of the Essence

    Guidelines recommend epinephrine as the primary medical intervention for cardiac arrest. However, no randomized trial data are available to support this recommendation. In this observational study from the American Heart Association's Get With The Guidelines—Resuscitation multi-center registry of in-hospital cardiac arrest, the authors sought to determine if timing of epinephrine administration in the setting of non-shockable (i.e. pulseless electrical activity or asystole) in-hospital cardiac arrest is associated with patient outcomes. Among 25,095 patients with non-shockable in-hospital cardiac arrest, the median time to first epinephrine was 3 minutes (IQR 1–5 minutes). When analyzed at 3 minute intervals, there was a stepwise decrease in survival to discharge with increasing time to epinephrine. As compared to 1–3 minutes, the …
