摘　　要：目的探究神经刺激器定位应用于肌间沟臂丛神经干阻滞的临床效果,分析其临床意义。方法 124例进行肌间沟臂丛神经阻滞手术的患者,采用抽签的方式分为对照组和观察组,各62例。对照组患者当刺激到神经,肌肉发生抽搐,即可给予阻滞;观察组患者需分别刺激臂丛神经干的上端、中端以及下端,并相应引起患者前臂提起、前臂外展以及前臂内收,即可给予阻滞。记录两组患者阻滞的起效时间以及成功率。结果观察组患者阻滞的起效时间以及成功率明显优于对照组,差异具有统计学意义(P<0.05)。结论采用神经刺激器引导的方式定位肌间沟臂丛神经干,阻滞效果显著,起效时间快,成功率较高。Objective To investigate clinical effect of nerve stimulator location applied in interscalene brachial plexus nerve block, and to analyze its clinical significance. Methods A total of 124 patients undergoing interscalene brachial plexus nerve block operation were randomly divided into control group and observation group, with 62 cases in each group. The control group received nerve block when muscle twitches under nerve stimulation. The observation group received nerve block after recording forearm lifting, forearm abduction, and forearm adduction under nerve stimulation in upper, middle and lower segment of brachial plexus nerve trunk. Records were made on block onset time and success rate of the two groups. Results The observation group had much better block onset time and success rate than the control group, and the difference had statistical significance（P〈0.05）. Conclusion Implement of nerve stimulator for interscalene brachial plexus nerve trunk location can provide remarkable block effect with quick onset time and high success rate.
