目的：研究超声引导神经刺激仪在臀下入路坐骨神经阻滞麻醉中的临床应用效果。方法50例足部手术患者，按照数字表法随机分为2组。对照组与观察组每组25例，对照组采用常规神经刺激仪经臀下入路进行坐骨神经阻滞麻醉，观察组在超声引导下辅助神经刺激仪行臀下入路坐骨神经阻滞麻醉，2组穿刺成功后均注入0．4％罗哌卡因25 ml，观察2组患者的穿刺次数（2．5±1．0）次、药物起效时间（14．2±6．1）min以及穿刺成功率。结果观察组的穿刺次数、药物起效时间均明显小于神经刺激仪引导组（P＜0．01），但2组麻醉阻滞效果差异无统计学意义（P＞0．05）。结论超声引导神经刺激仪在臀下入路坐骨神经阻滞中，穿刺次数、药物起效时间优于单纯使用神经刺激仪麻醉，可在临床中推广应用。

Objective To investigate the effect of subgluteal sciatic nerve blocking by ultrasound-guided peripheral nerve stimulator.Methods Fifty surgical patients who received foot surgery were randomly divided into two groups, the control group and the observation group, each consisting of 25 patients.The patients in the control group had sciatic nerve blocking by using conventional nerve stimulator, while the patients in the observation group received sciatic nerve blocking by subgluteal sciatic nerve blocking by ultra-sound-guided peripheral nerve stimulator.Upon completion of puncture, the patients in the 2 groups were injected with 0.4% ropiva-cain (25ml) .Then, observations were made on the number of puncture, the onset time of medication and success rate of puncture in the 2 groups.Results The number of puncture and the onset time of medication in the observation group were obviously lower than those of the patients with conventional nerve stimulator (P<0.01), however, no statistical significance could be noted in the effect of nerve blocking, when comparisons were made between the 2 groups(P>0.05).Conclusion Subgluteal sciatic nerve blocking by ul-trasound-guided peripheral nerve simulator was superior to subgluteal sciatic nerve blocking in the number of puncture and the onset time of medication, and was worth further clinical extension.
