目的 观察老年患者髋关节置换手术中应用超声引导下髂筋膜间隙阻滞的麻醉效果和术后阵痛效果。方法 回顾性分析2018年1月—2021年1月收治的80例髋关节置换手术的老年患者,观察组40例选择超声引导下髂筋膜间隙阻滞,对照组40例不进行髂筋膜间隙阻滞。对比不同时间点疼痛评分检测值,手术后不同时间患肢运动阻滞Bromage评分监测、不良反应评定值。结果 观察组术后6、12、24、48 h疼痛评分低于对照组,组间对比（P<0.05）;手术完成后的2、24、48 h,两组患肢运动阻滞Bromage评分无差异（P>0.05）;观察组不良反应率低于对照组（P<0.05）。结论 对于收治的髋关节置换手术的老年患者在治疗过程中开展超声引导下髂筋膜间隙阻滞,术后的镇痛效果更显著,且也不会造成不良反应,不影响术后患肢运动阻滞,预后理想。

Objective To observe the effect of ultrasound-guided fascia iliac space block on anesthesia and postoperative pain in elderly patients undergoing hip arthroplasty. Methods From January 2018 to January 2021, a total of 80 elderly patients with hip replacement surgery were randomly selected and divided into two groups. Forty cases in the study group were treated with ultrasound-guided fascia iliac space block, and another 40 cases in the control group were not given fascia iliac space block. Pain score, Bromage score of affected limbs, and adverse reactions were evaluated at different time points after operation. Results The pain scores of the study group at 6, 12, 24 and 48 h after operation were lower than those of the control group （P<0.05）. At 2, 24, and 48 h after operation, there was no difference in Bromage score of motor block between the two groups （P>0.05）. The adverse reaction rate of the study group was lower than that of the control group （P<0.05）. Conclusion Ultrasound-guided fascia iliac space block in the treatment of elderly patients undergoing hip replacement surgery has a significant postoperative analgesic effect, and does not cause adverse reactions or affect the postoperative limb motor block, showing ideal prognosis.
