Abstract:
OBJECTIVE:To observe the anesthesia effect and safety of hypoxia flow sevoflurane combined with propofol for el-derly abdominal tumor surgery in saturation. METHODS:128 elderly patients took abdominal tumor surgery under general anesthe-sia were randomly divided into observation group(64 cases)and control group(64 cases). After routine anesthetic induction,the oxygen flow was adjusted to 6 L/min,vaporizer was adjusted to 2%,10 minutes after inhalation,the observation group was adjust-ed to 0.5 L/min,and control group was 1.5 L/min,all received 0.5 mg/L propofol by target-controlled infusion,continuous infu-sion of remifentanil,intermittent bolus injection of vecuronium 1-2 mg/times based on the intraoperative muscle relaxation. Heart rate(HR),mean arterial pressure(MAP),oxygen saturation(SpO2),central venous pressure(CVP),inspired oxygen concentra-tion(FiO2),end-tidal carbon dioxide partial pressure [p(CO2)] in 10 min(T0),intraoperative 1 h(T1),intraoperative 2 h(T2), end of surgery(T3)in 2 groups were observed;sevoflurane dosage,recovery time,restlessness,and blood urea nitrogen(BUN), serum creatinine (Cr),alanine aminotransferase (ALT) levels,incidence of early cognitive dysfunction before and after surgery and the incidence of adverse reactions in 2 groups were recorded. RESULTS:There were no significant differences in the HR, MAP,SpO2,CVP,FiO2 and p(CO2)in 2 groups at different time points(P>0.05). The sevoflurane dosage,recovery time,the incidences of cognitive dysfunction postoperative 3 h and 6 h and adverse reactions in observation group were significantly lower than control group,the differences were statistically significant (P<0.05). And there were no significant differences in the cases with restlessness and incidence of cognitive dysfunction postoperative 1 d and 3 d(P>0.05). After surgery,ALT levels in 2 groups were significantly higher than before,the difference was statistically significant(P<0.05),but there was no significant difference between 2 groups (P>0.05). There were no significant differences in preoperative ALT and preoperative and postoperative BUN and Cr between 2 groups(P>0.05). CONCLUSIONS:Hypoxia flow sevoflurane combined with propofol shows obvious anesthe-sia effect for elderly abdominal tumor surgery in saturation,with stable hemodynamics,it can reduce sevoflurane dosage,shorten the recovery time and reduce the incidence of early postoperative cognitive dysfunction,with good safety.
