Key Points
- To assess the one-year prevalence of intraoperative cardiac arrest and determine the 30-day post-event survival rate in a tertiary hospital setting.
- Prospective cohort study analyzing 40,379 non-cardiac surgical anesthesia cases conducted from January to December 2007 at a tertiary teaching hospital.
- Data on patient characteristics, pre-arrest conditions, intraoperative interventions, resuscitation care, and 30-day outcomes were documented by anesthesiologists using a modified Utstein reporting template.
- Intraoperative cardiac arrest occurred in 52 patients, representing an incidence of 13 per 10,000 anesthetic procedures.
- Spontaneous return of circulation was achieved in 69% of arrest cases, but only 25% survived to 30 days post-arrest.
- Reduced survival was associated with ASA physical status IV and V, emergency surgical procedures, hemorrhagic events, hypovolemia as the primary arrest etiology, and intra-arrest atropine administration.

Intraoperative cardiac arrest in non-cardiac surgery is rare (13 per 10,000 procedures) but carries a poor prognosis, with only 25% of patients surviving to 30 days.
