What are the predictors of intraoperative cardiac arrest in adults undergoing noncardiac surgery?
Intraoperative blood loss, surgical urgency, and baseline health status are key predictors of intraoperative cardiac arrest during noncardiac surgery, highlighting the need for primary prevention due to high case fatality.
Intraoperative blood loss as indicated by the amount of transfusion was the most important predictor of ICA. The urgency of surgery and the preoperative composite indicators of health such as American Society of Anesthesiologists status and functional status were other important risk factors. The high case fatality suggests that primary prevention might be the key to reducing mortality from ICA.
