目的:探讨坐骨神经联合股神经阻滞对老年糖尿病胫骨横向骨搬移术患者血流动力学的影响。方法:按照组间基线资料匹配的原则，将我院2017年4月至2020年4月期间121例接受胫骨横向骨搬移术的老年糖尿病患者进行分组，对照组60例予以硬膜外麻醉，观察组61例予以坐骨神经联合股神经阻滞，观察两组麻醉效果、血流动力学及不良反应。结果:两组患者感觉、运动神经阻滞起效时间对比差异无统计学意义(n P>0.05)，但观察组患者感觉神经阻滞持续时间较对照组长，运动神经阻滞持续时间较对照组短(n P0.05)，对照组T1～T4 DBP、SBP及HR较T0明显降低且低于观察组(n P<0.05)；观察组术后不良反应发生率(1.64%)较对照组(13.33%)低(n P 0.05), but the duration of sensory nerve block in the observation group was longer than that in the control group, and the duration of motor nerve block was shorter than that in the control group (n P0.05). The T1 to T4 DBP, SBP and HR in control group was significantly lower than T0 and lower than the observation group (n P<0.05). The incidence of postoperative adverse reactions in the observation group (1.64%) was lower than that of the control group (13.33%) (n P<0.05).n Conclusion:The combination of sciatic nerve and femoral nerve block can stabilize the hemodynamics of elderly diabetic patients undergoing lateral tibial transfer, which can improve the anesthesia effect, and reduce the occurrence of adverse reactions.
