OBJECTIVE:To investigate the effects of sevoflurane combined with remifentanil on intraoperative related indica-tors and quality of postoperative recovery in patients with general anesthesia. METHODS:52 patients with elective abdominal sur-gery were randomly divided into observation group and control group. All patients were treated with etomidate 0.3 mg/kg+atracuri-um 0.5 mg/kg+remifentanil 1μg/kg for anesthesia induction;then observation group was received sevoflurane by inhalation and con-trol group was propofol by infusion. The SBP,DBP,HR and BIS in 2 groups were recorded before anesthesia induction(T0),after anesthesia induction(T1),time of intubation(T2),skin incision(T3),10 minutes after establishing pneumoperitoneum(T4),end of pneumoperitoneum(T5) and extubation(T6),respectively. Operation and anesthesia duration,recovery time and extubation time, MMSE score and incidence of adverse reactions were recorded. RESULTS:SBP and HR in T6 and DBP in T4-6 in 2 groups were sig-nificantly higher than T0 of same group,BIS in T1-5 was significantly lower than T0,the differences were statistically significant(P<0.05),however,there was no significant difference between 2 groups (P>0.05). Recovery time and extubation time in observa-tion group were significantly lower than control group(P<0.05),there was no significant difference in the operation and anesthesia duration between 2 groups(P>0.05). MMSE scores in 2 groups were significantly lower than before after 0.5 h and 1 h of extuba-tion,and control group was lower than observation group(P<0.05 or P<0.01);MMSE scores in 2 groups were significantly high-er than 0.5 h and 1 h after extubation(P<0.05),however,there was no significant difference between 2 groups and before(P>0.05). There was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Sevoflurane combined with remifentanil has satisfactory anesthesia,sevoflurane has better controllability,with good safety.
