ABSTRACT
Objective To compare the effects of different methods of general anesthesia on postoperative cognitive function in patients undergoing non-cardiac surgery.Methods One thousand ASA Ⅰ or Ⅱ patients,aged 18-60 years and undergoing non-cardiac surgery,were randomly divided into five groups (n=200 each)isoflurane + propofol + fentanyl group (group IPF),isoflurane + remifentanil group (group IR),sevoflurane + propofol + fentanyl group (group SPF),sevoflurane + remifentanil group (group SR),and propofol + remifentanil group (group PR).Two hundred patients receiving non-operative treatment served as control group (group C).In groups IPF and SPF,anesthesia was maintained with inhalation of 1.68% isoflurane or 1.71% sevoflurane,target controlled infusion (TCI) of propofol with the target plasma concentration of 2-5 μg/ml,and intermittent intravenous boluses of fentanyl.In groups IR,SR and PR,anesthesia was maintained with inhalation of 1.68% isoflurane or 1.71 % sevoflurane,or TCI of propofol with the target plasma concentration of 2-5 μg/ml,and TCI of remifentanil with the target plasma concentration of 2-6 ng/ml.The patients' cognitive function was assessed with minimental state examination (MMSE) 1 day before operation,when leaving the post-anesthetic care unit (PACU),and 1 and 3 days after operation,respectively.Z score was used to identify the cognitive dysfunction as recommended by Moiler when leaving the PACU,and 1 and 3 days after operation.Results Compared with group C,the MMSE score was significantly decreased when leaving the PACU,and the incidence of cognitive dysfunction increased when leaving the PACU and 1 day after operation in the other groups (P < 0.05).Compared with groups IPF,IR,SPF and PR,the incidence of cognitive dysfunction was significantly increased in group SR (P<0.05).Conclusion General anesthesia with sevoflurane combined remifentanil exerts fewer effects on the postoperative cognitive function in patients undergoing non-cardiac surgery.
