Abstract 【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 100.00% while that in the control group was 88.89% (P＜0.05). 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＜0.05). The excellent rate of anesthesia in the observation group was 97.22% while that in the control group was 83.33% (P＜0.05). The excellent and good rate in the two groups was 100.00%. The total score of anesthetics around neural stem in the observation group was (136.8±6.34) while that in the control group was (115.36±10.58),the difference was significant (P＜0.05). There was no significant difference between the two groups in the incidence of postoperative complications (P＞0.05). 【Conclusion】Compared with the nerve stimulator, the success rate of ultrasound 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.
