Association between calcium administration and outcomes during adult cardiopulmonary resuscitation at the emergency department.

Objectives: Calcium administration during cardiac arrest is limited in some circumstances, mainly due to lack of consistent evidence. This study aims to investigate whether calcium therapy administered during cardiac arrest at the Emergency Department is associated with good outcomes, including the probability of return of spontaneous circulation (ROSC), survival to hospital admission, survival to hospital discharge, and favorable neurological outcome at discharge.

Methods: We retrospectively reviewed 599 consecutive adult cardiac arrest events between 2016 and 2018.
