Abstract:
Objective To compare the effects of isoflurane compare sevoflurane on postoperative cognitive function and the level of serum β-amyloid in elder patients at 12 months after surgery.Methods Seventy-seven patients undergoing abdominal surgery,43 males and 34 females,aged 65-75 years,ASA physical status Ⅰ-Ⅲ,were divided into two proups:isoflurane group (group Ⅰ,n =32) and sevoflurane group (group S,n =45).The patients' cognitive function were assessed using mini-mental state examination (MMSE) 1 d before operation,3 d and 12 months after opertion.Blood samples were taken before operation,3 d and 12 monthes after operation for determination of serum Aβ42 and Aβ40 concentrations.Results The MMSE scores of the two groups 3 d after operation were significantly lower than those before operation (P＜0.05).The MMSE score 3 d after operation in group Ⅰ was significantly lower than that in group S (P＜0.05).The incidence of cognitive dysfunction 12 months after operation had no significant difference between two groups [13 (40.6％) cases vs 15 (33.3％) cases].There was no significant difference in the serum Aβ42 and Aβ40 concentration between groups.Conclusion Sevoflurane has less effect on postoperative cognitive function in short time than isoflurane,but its long-term effect seemed to be similar.The levels of Aβ42 and Aβ40 showed no difference between two groups.
