摘　　要：目的:比较外周神经刺激器(PNS)定位技术与异感定位法在行锁骨下臂丛神经阻滞的效果。方法:对150例行上肢前臂、腕、手掌、手指手术的患者随机分为神经刺激定位组(PNS组)和传统异感定位组(对照组),每组75例。PNS组采用PNS辅助定位,对照组采用异感定位。0.375%罗派卡因局麻药。完成阻滞后,比较两组阻滞效果。结果:PNS组神经阻滞完全72例,阻滞不全3例;对照组神经阻滞完全50例,阻滞不全19例,阻滞失败6例。PNS组神经阻滞的成功率显著高于对照组(P<0.05)。结论:PNS定位较异感定位更精确,阻滞成功率高,是一种安全、有效的麻醉方法。Objective： To compare the effects of using peripheral nerve stimulator（PNS） as nerve locator and that of using paresthesia positioning method in the infraclavicular brachial plexus block.Methods： 50 cases that underwent surgery of upper forearm,wrist,hand or finger were divided into PNS group and control group by half.PNS was applied to infraclavicular brachial plexus block for patients in the PNS group while paresthesia positioning method was adopted for those in the control group.0.375% ropivacaine was administrated for local anesthesia in both groups.After the block procedure was finished,compare the anesthesia effects of these two groups.Results： 72 and 3 cases in the PNS group demonstrated complete block and partial block respectively,and 50 cases in the control group showed complete block,19 partial block and 6 failed.There is significant difference between the success rate of the two groups（P〈0.05）.Conclusion： Compared with paresthesia positioning method,PNS,using as nerve locator is more accurate in infraclavicular brachial plexus block with higher success rate.
