OBJECTIVE: To test the hypothesis that improvements in intraoperative and perioperative critical care are resulting in an improved outcome after intraoperative cardiac arrest. DESIGN: A retrospective consecutive series of patients who experienced an intraoperative cardiac arrest during noncardiothoracic surgical procedures between January 1986 and June 1994. SETTING: A tertiary care university-based hospital. PARTICIPANTS: Twenty-four consecutive patients who experienced an intraoperative arrest among 162,661 noncardiothoracic surgical procedures during the designated period. INTERVENTION: Advanced cardiac life support and advanced trauma life support methods were used appropriately. Postarrest pharmacologic and mechanical cardiopulmonary support were used as needed in the setting of a surgical intensive care unit. MAIN OUTCOME MEASURES: Survival out of the operating room and survival to discharge. RESULTS: Fifteen patients (62%) were resuscitated in the operating room and taken to the surgical intensive care unit or recovery room. Nine patients (38%) survived to discharge from the hospital. Twelve arrests (50%) were primarily cardiac in origin. Predictors of mortality included a need for pressor or inotropic support (P < .001) and duration of the arrest greater than 15 minutes (P < .001). CONCLUSION: Survival from an intraoperative cardiac arrest in a noncardiothoracic surgical patient is much improved over rates in historical controls who experienced in-hospital and out-of-hospital cardiac arrest. Rapid identification and aggressive correction of mechanical and metabolic derangements is warranted.
