ABSTRACT
Objective To observe effects of different concentrations of sevoflurane combined with propofol on recovery quality in patients undergoing partial hepatic resection.Methods Seventy-eight patients,aged 20-70 years old,selected for partial hepatic resection were randomly divided into three groups,26 patients in each group:total intravenous propofol anesthesia group (group T), propofol combined with 0.5 MAC sevoflurane anesthesia group (group S1),propofol combined with 1.0 MAC sevoflurane anesthesia group (group S2).Spontaneous respiration recovery time,recovery time,extubation time and modified Aldrete score of 9 time were recorded after operation.Modified OAA/S scores as well as modified Aldrete score at extubation immediate time (T1 )and 5 min (T2 ), 1 5 min(T3 ),30 min(T4 )after extubation were also recorded.Results Total amount of propofol in groups S1,S2 significantly less than group T and total amount of propofol in group S2 significantly less than group S1(P <0.05).The recovery time,extubation time,modified Aldrete score of 9 time in groups S1 and S2 were significantly shorter than group T (P <0.05).Modified OAA/S scores at T1 ,T2 and the modified Aldrete scores at T1 in both groups S1 and S2 were significantly higher than group T,while group S2 was significantly higher than group S1 (P <0.05).Conclusion Compared with total intravenous propofol anesthesia,both propofol combined with 0.5 MAC sevoflurane and propofol combined with 1.0 MAC sevoflurane anesthesia improves the recovery quality in patients un-dergoing partial hepatic resection,and the recovery time was decreased in propofol combined with 1.0 MAC sevoflurane anesthesia.
