Podcast 741: Calcium for Cardiac Arrest

Contributor: Aaron Lessen, MD

Educational Pearls:

  • Study of nearly 400 patients evaluating giving calcium during cardiac arrest with the endpoint as return of spontaneous circulation (ROSC)
  • Compared giving 1 amp calcium chloride with each round of epinephrine for the first two rounds of epinephrine versus saline placebo
  • ROSC occurred in 19% of patients in the calcium groups versus 27% in saline placebo group
  • No magic drugs in cardiac arrest, good CPR and early defibrillation are still the most important factors for ROSC in cardiac arrest
