[目的]比较超声与神经刺激仪引导坐骨神经联合股神经阻滞用于大隐静脉高位结扎剥脱术中的麻醉效果.[方法]将拟行神经阻滞麻醉手术的72例大隐静脉曲张患者随机分为观察组(超声引导)与对照组(神经刺激仪引导),比较两组麻醉效果及相关情况.[结果]观察组阻滞成功率为1000.0%(36/36),高于对照组888.9%(32/36)(P<00.5);观察组感觉阻滞起效时间早于、维持时间长于、第1次辅助药物镇痛使用时间晚于对照组(P<00.5);观察组麻醉优率97.22%(35/36)高于对照组的83.33%(30/36)(P<0.05),两组优良率均为1000.0%;观察组麻醉药物包绕神经干总评分为(1368.±63.4)分,高于对照组的(1153.6±105.8)分,且差异有显著性(P00.5).[结论]相比神经刺激仪,超声引导坐骨神经、股神经联合阻滞成功率显著较高,起效时间更快,维持时间更长,麻醉质量更好.“,”[Objective] To compare and analyze the anesthetic effects of sciatic nerve block and femoral nerve block guided by Ultrasound and nerve stimulator in high ligation and stripping of great saphenous vein .[Methods]Seventy-two cases of patients with varicosis of great saphenous veins who were going to be treated with surgery under nerve block anesthesia were randomly divided into the observation group (ultrasound guided) and the control group (nerve stimulator guided) .The block effects were compared between the two groups .[Results] The success rate of block in the observation group was 1000.0% while that in the control group was 888.9% ( P <00.5) .The onset time of sensory block was significantly earlier ,duration was significantly longer and time of firstly using auxiliary analgesics was significantly later in the observation group than the control group ( P <00.5) .The excel-lent rate of anesthesia in the observation group was 972.2% while that in the control group was 833.3% ( P <00.5) .The excellent and good rate in the two groups was 1000.0% .The total score of anesthetics around neural stem in the observation group was (1368.± 63.4) while that in the control group was (1153.6 ± 105.8) ,the differ-ence was significant ( P 00.5) .[Conclusion]Compared with the nerve stimulator ,the success rate of ul-trasound guided sciatic nerve and femoral nerve block is significantly higher ,the onset time is earlier ,the duration is longer ,and the quality of block is higher .
