Study: Survival From Cardiac Arrest Highest In OR, Post-Anesthesia Care Unit

University of Michigan study from the “Online First” edition of Anesthesiology found cardiac arrest was associated with improved survival when it occurred in the operating room (O.R.) or post-anesthesia care unit (PACU) compared to other hospital locations. The findings offer evidence that the presence of anesthesia providers in these locations may improve outcomes for certain patients.

Cardiac arrest is a very uncommon complication during the perioperative period, which includes the time during and immediately after surgery and anesthesia. An estimated seven arrests occur per every 10,000 patients undergoing non-cardiac surgery each year. In the past, outcomes of cardiac arrest in the perioperative period have not been well-studied.

To better understand the management and outcomes of cardiac arrests during the perioperative period, researchers used the “Get With The Guidelines® - Resuscitation” registry, a national cardiopulmonary resuscitation registry supported by the American Heart Association. Researchers identified more than 2,500 instances of perioperative cardiac arrest from 234 hospitals.

Findings showed one in three patients survived cardiac arrest to hospital discharge. Of these patients, two of three had good brain function. In addition, survival was approximately 25-65 percent higher if the cardiac arrest occurred in the O.R. or PACU than if it occurred in the intensive care unit (ICU) or general in-patient areas.
