股神经联合坐骨神经阻滞麻醉用于老年单侧下肢手术的麻醉效果及对血流动力学的影响

目的:研究股神经联合坐骨神经阻滞麻醉用于老年单侧下肢手术的麻醉效果及对血流动力学的影响。方法:选取2014年1月到2015年1月我院收治的老年单侧下肢手术患者70例,按照随机数字表法将患者分为研究组和对照组,每组35例,研究组给予股神经联合坐骨神经阻滞麻醉,对照组给予蛛网膜下腔麻醉,比较两组麻醉效果,麻醉前、麻醉15 min、麻醉半小时收缩压(SBP)、舒张压(DBP)、心率(HR),并观察不良反应的发生率。结果:麻醉15 min、半小时后对照组SBP和DBP显著低于研究组,也显著低于麻醉前,比较差异有统计学意义(P0.05),研究组麻醉15 min、半小时后SBP和DBP与麻醉前比较无统计学意义(P0.05),麻醉15 min、半小时后两组HR与麻醉前比较无统计学意义(P0.05);研究组不良反应发生率显著低于对照组,两组比较差异具有统计学意义(P0.05)。结论:股神经联合坐骨神经阻滞麻醉用于老年单侧下肢手术麻醉效果与蛛网膜下腔麻醉相当,对血流动力学影响较少,安全性较高。

Femoral Nerve Combined with Sciatic Nerve Block Anesthesia for Elderly Patient Undergoing Unilateral Lower Limb Operation : Its Effect and Influence on Hemodynamics

Objective:To study the effect of femoral nerve combined with sciatic nerve block anesthesia in elderly patient undergoing unilateral lower limb operation and its influence on hemodynamics.Methods:A total of 70 elderly patients, who underwent unilateral lower limb operation in Sports Affiliated Hospital of Chengdu Sport Collage fromJanuary 2014 to January 2015, were selected and randomly divided into study group(n=35) and control group (n=35). The study group was treated with femoral nerve combined with sciatic nerve block anesthesia, while the control group, with subarachnoid anesthesia. The systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) before anesthesia, 15 min after anesthesia, and half an hour after anesthesia in the two groups were recorded and compared, and the incidence of adverse reactions was observed.Results:SBP and DBP 15min and half an hour after anesthesia in the control group were significantly lower than those in the study group and before anesthesia, the differences were statistically significant (P<0.05), while compared with before anesthesia, there was no significant difference in SBP and DBP 15 min and half an hour after anesthesia in the study group (P>0.05). Compared with before anesthesia, there was no significant difference in HR 15min and half an hour after anesthesia in the two groups (P>0.05). The incidence of adverse reactions in the study group was significantly lower than that in the control group, the difference was statistically significant (P<0.05).Conclusion:The effect of femoral nerve combined with sciatic nerve block anesthesia is equivalent to subarachnoid anesthesia for elderly patient undergoing unilateral lower limb operation, but the former has less influence on hemodynamics and higher safety.
