目的 探析在老年髋部手术麻醉中采用B超联合神经刺激仪引导髂筋膜阻滞麻醉对血流动力学的影响。方法 从2019年5月—2022年5月期间行髋部手术的老年患者中选择40例回顾性分析,根据麻醉方式的不同将其分为对照组和观察组,对照组20例接受椎管内麻醉,观察组20例接受B超联合神经刺激仪引导髂筋膜阻滞麻醉。对比两组麻醉效果、血流动力学[舒张压（DBP）、收缩压（SBP）、心率（HR）、血氧饱和度（SpO₂）]水平。结果 观察组麻醉总有效率为95.00%,低于对照组的100.00%,差异无统计学意义（P>0.05）;观察组麻醉30 min后DBP、SBP、HR、SpO₂水平均高于对照组（P<0.05）。结论 在老年髋部手术中采用B超联合神经刺激仪引导髂筋膜阻滞麻醉,可使患者血流动力学水平波动较小,麻醉效果良好,但椎管内麻醉更佳。

Objective To explore the hemodynamic effects of iliac fascia block anesthesia guided by B-ultrasound combined with nerve stimulator during hip surgery in the elderly. Methods From May 2019 to May 2022, 40 elderly patients who underwent hip surgery were selected and analyzed retrospectively. They were divided into a control group and an observation group according to anesthesia methods. Twenty patients in the control group received intraspinal anesthesia, and 20 patients in the observation group received B-ultrasound combined with nerve stimulator guided iliac fascia block anesthesia. The anesthetic effect, hemodynamics [diastolic blood pressure （DBP）, systolic blood pressure （SBP）, heart rate （HR）, and blood oxygen saturation （SpO₂）] levels were compared between the two groups. Results The total effective rate was 95.00% in the observation group, which was lower than 100.00% in the control group, with no statistical significance （P>0.05）. The levels of DBP, SBP, HR, and SpO₂ in the observation group were higher than those in the control group after 30 min of anesthesia （P<0.05）. Conclusion The use of B-ultrasound combined with nerve stimulator-guided iliac fascia block anesthesia in elderly hip surgery can make the hemodynamic level of patients fluctuate less, and its anesthesia effect is good, but the spinal anesthesia is better.
