Abstract:
Objective To systematically review the influence of propofol orsevoflurane on postoperative cognitive dysfunction(POCD) in elderly patients undergoing non-cardiac surgery.Methods Eight databases including Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, Pubmed, CNKI, VIP, CBM and Wanfang Database were searched for randomized controlled trials (RCT) about the influence of propofol orsevoflurane on POCD in elderly patients from the time of database establishment to June, 2016.At the same time, the reference materials of included literature were retrieved manually.All data were selected and evaluated by three independent reviewers according to the inclusion and exclusion criterions.RevMan 5.1 was used for the data analysis.Results A total 14 trials were discovered involving 790 elderly patients undergoing non-cardiac surgery.The results of Meta-analysis showed that the eye opening time and extubation time in the propofol group were significant shorter than sevoflurane group[SMDeye opening=-0.83,95%CI(-1.05,-0.61),P<0.05;SMDextubation=-0.85,95%CI(-1.09,-0.62),P<0.05].The MMSE scores at 1,3 and 6 h respectivelyafter the operation were obviously higher than those of sevoflurane group[SMD1h =0.84,95%CI(0.61,1.08),P<0.05;SMD3 h=1.12,95%CI(0.86,1.38),P<0.05;SMD6h=0.61,95%CI(0.40,0.82),P<0.05].One day after the operation,the difference was not significant[SMD1d=0.14,95%CI(-0.03,0.31),P>0.05].Three days after the operation, the values returned to normal levels, and was still higher in propofol group than in sevoflurane group[SMD3d=-0.32,95%CI(-0.56,-0.07),P<0.05] until 7 d [SMD7d=-0.18,95%CI(-0.51,0.15),P>0.05].The odds ratio of POCD incidence between propofol and sevoflurane groups was 0.35 [95%CI(0.21,0.58),P<0.05].Conclusion Propofol may lead to shorter eye opening time and extubation time compared to sevoflurane in elderly patients undergoing non-cardiac surgery.Both groups may lead to POCD, while propofol is a better choice for elderly patients when choosing general anesthesia.
