脑电双频指数监测下全身麻醉用于合并高血压老年患者的临床观察

目的观察在脑电双频指数(BIS)监测下实施全身麻醉对合并高血压老年患者血流动力学和麻醉恢复的影响。方法 80例择期行腹腔镜下胆囊切除手术的老年高血压患者,随机分为BIS组和对照组,BIS组依据BIS监测值调整麻醉深度,对照组患者根据麻醉医生经验调整麻醉深度。记录两组患者麻醉期间血压和心率的变化以及麻醉恢复情况。结果在气管插管后1min,BIS组患者收缩压、舒张压和心率均低于对照组,差异均有统计学意义(t分别=-3.26、-3.41、-4.25,P均<0.05);BIS组患者麻醉恢复时间为(18.60±6.08)min,对照组为(26.22±7.37)min,两者比较,差异有统计学意义(t=-8.47,P<0.05)。结论 BIS监测使老年高血压患者全身麻醉期间血压和心率波动小,麻醉恢复快,并发症少。

Clinical application of bispectral index monitoring during general anesthesia for the elderly hypertension patients

Objective To investigate the effects of bispectral index monitoring during general anesthesia on hemodynamics,recovery time and post-anesthesia complication in the elderly patients with hypertension.Methods Eighty ASA II-III elderly patients（age≥65 years old） undergoing laparoscopic cholecystectomy were randomly assigned to control group and BIS group.The general anesthesia was achieved by infusion of remifentanil and propofol in titrated doses.The depth of anesthesia was titrated according to the BIS value for the patients of the BIS group,and it was titrated according to experience of anesthetist in the control group.The blood pressure and heart rate were monitored.The recovery level was evaluated and post-anesthesia complications were recorded.Results In the control group,changes in blood pressure and heart rate were significant（t =-3.26,-3.41,-4.25,P 0.05）.The recovery time（18.60±6.08） min in the BIS group was shorter than those of control group（26.22±7.37） min（t=-8.47,P0.05）.Conclusions The BIS monitoring during the general anesthesia provides satisfactory hemodynamic stability,minor post-anesthesia complication,and rapid recovery.
