Abstract
Objective To systematically evaluate the effectiveness of the Bispectral Index(BIS)in monitoring anesthesia depth.Methods CNKI,Wanfang,VIP,SinoMed,Ovid-MEDLINE,Cochrane Library,PubMed,Web of Science and Embase databases were searched,and all relevant randomized controlled trials were collected according to inclusion and exclusion criteria.Literature screening,data extraction,and methodological quality were assessed independently by two evaluators.R 4.0 software was used for analysis.Results A total of 92 studies were included.Compared to traditional depth monitoring of anesthesia,BIS monitoring significantly reduced the incidence of postoperative delirium(RR=0.56,95%CI:0.42~0.75,P<0.01),intraoperative awareness(RR=0.51,95%CI:0.36~0.74,P<0.01),and postoperative cognitive impairment(RR=0.77,95%CI:0.67~0.89,P<0.01).Additionally,it substantially shortened the time to eye opening(MD=-2.55,95%CI:-3.75~-1.35,P<0.01),recovery time to orientation(MD=-5.38,95%CI:-8.94~-1.82,P<0.01),extubation time(MD=-5.65,95%CI:-7.13~-4.17,P<0.01),and post-anesthesia care unit stay time(MD=-9.47,95%CI:-13.50~-5.43,P<0.01),while also reducing the amount of anesthesia drugs used(SMD=-1.02,95%CI:-1.37~-0.67,P<0.01).There were no significant differences between the use of BIS monitoring and traditional depth monitoring of anesthesia in postoperative nausea and vomiting,the incidence of abnormal blood pressure,mortality,operation time,and predicted recovery of consciousness.Conclusion The use of BIS monitoring in anesthesia can significantly improve the effectiveness of clinical anesthesia management,contributing positively to ensuring both the safety of patients undergoing anesthesia and he safety of surgeries.关键词
