Abstract：Objective:The effect of ultrasound guidance combined with bispectral index(BIS)monitoring erector spinae plane block(ESPB)combined with general anesthesia in elderly patients with lumbar spine surgery.Method:A total of 106 elderly patients who received lumbar surgery in The Second Hospital of Sanming from September 2022 to September 2023 were selected as the study objects,and were divided into control group and observation group by random number table method,with 53 cases in each group.The control group was given general anesthesia under endotracheal intubation,while the observation group was given ultrasound guidance combined with BIS monitoring ESPB combined general anesthesia.Anesthesia related indexes,hemodynamic indexes[heart rate(HR),mean arterial pressure(MAP)],postoperative pain degree[visual analogue score(VAS)]and the occurrence of adverse reactions were observed between the two groups.Result:The effective time of anesthesia,extubation time and recovery time in the observation group were shorter than those in the control group,and the differences were statistically significant(P＜0.05).There was no significant difference in the comparison of preoperative hemodynamic indexes between the two groups(P＞0.05).HR and MAP levels in the observation group were significantly lower than those in the control group during and after the operation,and the difference was statistically significant(P＜0.05).6 h,12 h and 24 h after operation,VAS scores in the observation group were lower than those in the control group,and the difference was statistically significant(P＜0.05).The incidence of adverse reactions in observation group was lower than that in control group,and the difference was statistically significant(P＜0.05).Conclusion:Ultrasound-guided ESPB combined general anesthesia under BIS monitoring can shorten the onset and recovery time of anesthesia,maintain stable hemodynamic state,and reduce postoperative pain and incidence of adverse reactions in elderly patients undergoing lumbar surgery.
