ABSTRACT
Objective To investigate the effects of different anesthesia methods on oxidative stress in elderly patients undergoing neurosurgery.Methods Totally 60 patients undergoing neurosurgery were randomly divided into 3 groups:propofol group,isoflurane group and sevoflurane group (n-20 each group),heart rate(HR) and mean artery pressure(MAP) in all patients were recorded at the time points of pre anesthesia (T0),incision of skin (T1),incision of dura (T2),end of operation (T3).The activity of superoxide dismuase (SOD),catalase (CAT),and glutathione peroxidase (GSH-Px) were measured at the time of T0,6 h (T4),24 h (T5),48 h (T6),72 h (T7)after operation.The efficacy of anesthesia was evaluated by Glasgow Outcome Score (GOS) at 3 months after operation.Results The activity of SOD,CAT and GSH Px in 3 groups were lower at T5and T6 than at T0 (P<0.05).The SOD activity at T4,T5,T5and TTwere higher in propofol group [(87.2±11.8) U/ml,(75.1±12.4) U/ml,(84.6±9.3) U/ml,(92.5±12.5) U/ml,respectively]than in isoflurane group [(75.0±12.2) U/ml,(63.8±8.9) U/ml,(70.3±9.0) U/ml,(82.5±13.5) U/ml,respectively] and in sevoflurane group [(79.4±10.4) U/ml,(68.7±10.5) U/ml,(72.0±10.9) U/ml,(85.17±8.41) U/ml,respectively] (all P<0.05).The CAT activity at T5 was higher in propofol group [(66.59±7.21) U/ml] than in isaflurane group [(51.58±8.19) U/ml] and in sevoflurane group [(58.49±7.27) U/ml] (both P<0.05).The GSH-Px activity was higher at T4,T5and T6 in group propofol[(159.2 ± 20.8) U,(140.7 ± 16.2) U,(152.3 ± 19.1) U,respectively] than in isoflurane group [(129.4±17.9) U,(108.3±15.9) U,(118.4±14.1) U,respectively] and in sevoflurane group [(140.1±15.8) U,(125.2± 17.1) U,(137.9±10.7) U,respectively] (all P<0.05).The outcome of neurosurgery had no significant differences among the 3 groups (P>0.05).Conclusions Propofol has a better effect on oxidative stress than isoflurane and sevoflurane in elderly patients undergoing neurosurgery.
