术中脑电爆发抑制与患者术后转归

Research advances on the relationship between electroencephalogram burst suppression and postoperative outcomes

脑电爆发抑制(burst suppression,BS)作为临床麻醉中常见的神经电生理现象,越来越受到关注。研究发现,BS与患者年龄、基础状态以及麻醉管理等因素密切相关。但是,全麻期间BS与术后谵妄(postoperative delirium,POD)、术后认知功能障碍(postoperative cognitive dysfunction,POCD)以及病死率等并发症的关系仍存争议。文章阐述了BS的概念,对BS的影响因素、术中脑电BS与术后转归进行总结,期望能为临床麻醉管理提供参考。

Intraoperative electroencephalogram burst suppression(BS)is closely related to postoperative outcomes.Burst sup⁃pression 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.
