摘要：目的 探讨微量泵持续给药硬膜外麻醉在实施全髋关节置换术的高龄患者中的应用效果。方法 随机选取本院76例实施全髋关节置换术的高龄患者，时间选自2019年3月-2020年6月，随机分组，对照组（38例）与观察组（38例）分别实施硬膜外分次给药麻醉与微量泵持续给药硬膜外麻醉，对比麻醉效果。结果 心率方面，观察组切皮时比对照组低，差异明显（P<0.05）;平均动脉压方面，观察组切皮时及切皮后10min比对照组高，差异显著（P<0.05）。结论 高龄患者进行全髋关节置换术过程中，联合微量泵持续给药硬膜外麻醉方法，能够平稳患者血流动力学改变。

[Abstract]Objective To investigate the effect of continuous epidural anesthesia with micro pump in elderly patients undergoing total hip arthroplasty. Methods 76 cases of elderly patients with total hip arthroplasty in our hospital were randomly selected from March 2019 to June 2020. They were randomly divided into control group（38 cases）and observation group（38 cases）. Results the heart rate of the observation group was lower than that of the control group（P < 0.05）;In terms of mean arterial pressure，the observation group was significantly higher than the control group at the time of skin incision and 10 minutes after skin incision（P < 0.05）. Conclusion in the process of total hip arthroplasty in elderly patients，continuous epidural anesthesia combined with micro pump can stabilize the hemodynamic changes of patients.

采取全髋关节置换术治疗的高龄患者麻醉方法主要采用连续硬膜外麻醉【1】。在我国老龄化现象日益加重的背景下，采取全髋关节置换术治疗的高龄患者不断增多【2】。因为老年患者自身抵抗能力和免疫能力日渐减弱，再加之合并基础疾病，对于麻醉、手术等耐受性较差，手术治疗过程中，具有较高的风险发生率【3-4】。基于此，本次研究针对实施全髋关节置换术的高龄患者采取微量泵持续给药硬膜外麻醉的效果进行分析，具体如下。

1.1 资料

本次研究76例实施全髋关节置换术的高龄患者均为本院2019年3月-2020年6月接收，随机分组，各38例;对照组：男、女分别有20例与18例;年龄段：60-81岁，均值（74.65±3.12）岁;观察组：男、女分别有22例与16例;年龄段：60-83岁，均值（74.72±3.15）岁;一般资料方面，两組未见明显差异（P>0.05）。……
