Epinephrine Improves Outcomes in Out-Of-Hospital Cardiac Arrests.

Epinephrine use in cardiac arrest (CA) is associated with a greater likelihood of return of spontaneous circulation (ROSC) but this early potential benefit does not seem to translate to survival with good neurologic outcomes. Similarly, high-dose epinephrine may yield a small increase in ROSC but does not improve rates of hospital discharge, long-term survival, or improved neurologic outcomes compared to standard-dosed epinephrine. Higher cumulative doses of epinephrine (>3 mg) during CA has been consistently associated with poor neurologic outcomes following ROSC.
