摘　　要：目的:分析右美托咪定维持麻醉联合超声引导下臂丛神经阻滞麻醉(BPB)在老年肱骨近端骨折患者中的应用效果。方法:选取2023年1—12月于徐州市贾汪区人民医院行手术治疗的老年肱骨近端骨折患者作为研究对象,采用随机数字表法分为对照组和观察组,两组均为42例。对照组实施咪达唑仑维持麻醉联合超声引导下BPB,观察组实施右美托咪定维持麻醉联合超声引导下BPB。比较两组血流动力学指标、镇静效果及认知功能。结果:手术开始10 min(T_(1))、切皮时(T_(2)),观察组心率快于对照组(P<0.05);手术开始30 min(T_(3)),观察组心率慢于对照组(P<0.05)。T_(1)、T_(2)、T_(3)观察组平均动脉压低于对照组(P<0.05)。T_(1)、T_(2)、T_(3),观察组心率、平均动脉压比较,无统计学差异(P>0.05)。T_(1)、T_(2)、T_(3),对照组心率先减慢后加快(P<0.05)。T_(2)、T_(3),观察组平均动脉压低于T_(1)(P<0.05)。T_(1)、T_(2)、T_(3),观察组镇静效果满意占比高于对照组(P<0.05)。术后30 min、24 h、48 h,两组认知功能评分逐渐升高,且术后30 min、24 h,观察组认知功能评分高于对照组(P<0.05)。术后48 h,两组认知功能评分比较,无统计学差异(P>0.05)。结论:右美托咪定维持麻醉联合超声引导下BPB在老年肱骨近端骨折患者中的应用效果显著,可改善患者术中血流动力学指标,提高镇静效果,促进认知功能恢复。Objective:To analyze the application effect of dexmedetomidine anesthesia maintenance combined with ultrasoundguided brachial plexus block anesthesia(BPB)in elderly patients with proximal humeral fracture.Methods:A total of 84 elderly patients with proximal humeral fracture who received surgical treatment in the People's Hospital of Jiawang District of Xuzhou City from January 2023 to December 2023 were selected as the study subjects.The subjects were divided into control group and observation group according to random number table method,with 42 cases in each group.The control group received midazolam anesthesia maintenance combined with ultrasound-guided BPB.The observation group received dexmedetomidine anesthesia maintenance combined with ultrasound-guided BPB.The hemodynamic indexes,sedation effect and cognitive function of the two groups were compared.Results:At 10 min of surgery(T_(1))and when the skin was cut(T_(2)),the heart rate in the observation group was faster than that in the control group(P<0.05).At 30 min of surgery(T_(3)),the heart rate in the observation group was slower than that in the control group(P<0.05).At T_(1),T_(2)and T_(3),the mean arterial pressure in the observation groups was lower than that in the control group(P<0.05).There was no significant difference in heart rate and mean arterial pressure in the observation group at T_(1),T_(2)and T_(3)(P>0.05).At T_(1),T_(2)and T_(3),the heart rate in the control group first slowed down and then accelerated(P<0.05).At T_(2)and T_(3),the mean arterial pressure in the observation group was lower than that at T_(1)(P<0.05).At T_(1),T_(2)and T_(3),the proportion of satisfactory sedation effect in the observation group was higher than that in the control group(P<0.05).At 30 min,24 h and 48 h after surgery,the cognitive function scores in the two groups gradually increased;at 30 min and 24 h after surgery,the cognitive function scores in the observation group were higher than those in the control group(P<0.05).At 48 h after surgery,there was no s
