Intraoperative electroencephalogram burst suppression (BS) is closely related to postoperative outcomes. Burst suppression is associated with patients' age, baseline status, and anesthesia management. However, the relationship between BS during general anesthesia and postoperative delirium (POD), postoperative cognitive dysfunction (POCD), mortality, and other complications remains controversial. This article describes the concept of BS, and summarizes the influencing factors of BS, the relationship between intraoperative BS and postoperative outcomes, meaning to provide reference for clinical anesthesia management.
