Abstract
Objective:To investigate the application effect of axillary brachial plexus block combined general anesthesia in shoulder arthroscopic surgery under bispectral index(BIS)monitoring.Method:A total of 86 patients underwent shoulder arthroscopic surgery in General Hospital of Ningxia Medical University and Wuzhong People's Hospital from January 2020 to January 2023 were selected.The patients were divided into control group(supraclavicular brachial plexus block combined general anesthesia under BIS monitoring)and observation group(axillary brachial plexus block combined general anesthesia under BIS monitoring)according to random number table method,43 cases in each group.The heart rate(HR),mean arterial pressure(MAP)and BIS values were compared between the two groups at different times[before anesthesia(T0),immediately after tracheal intubation(T1),at incision(T2),and at extubation(T3)].The pain score[visual analogue scale(VAS)]and muscle strength score were compared between the two groups at the time of anesthesia awakening and 2 and 12 h after surgery.The intraoperative dosage of Sufentanil was compared between the two groups.The incidence of adverse reactions was compared between the two groups.Result:At T0,there were no significant differences in HR and MAP between the two groups(P>0.05).At T1,T2 and T3,HR and MAP in observation group were lower than those in control group,the differences were statistically significant(P<0.05).At T0,T1 and T2,there were no significant differences in BIS value between the two groups(P>0.05).The BIS value at T3 in the observation group was higher than that in the control group,the difference was statistically significant(P<0.05).VAS scores of the observation group were lower than those of the control group and muscle strength scores of the observation group were higher than those of the control group at the time of anesthesia awakening and 6 and 12 h after surgery,the differences were statistically significant(P<0.05).The intraoperative dosage of Sufentanil in the observation group was less than that in the control group(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusion:Axillary brachial plexus block combined general anesthesia under BIS monitoring has significant anesthetic effect in shoulder arthroscopic surgery,which can stabilize hemodynamics,and the postoperative pain degree of patients is less,the influence on muscle strength is less,and the safety is high.关键词
