1、临床麻醉学杂志2014年5月第3O卷第5期JClinAnesthesiol，May2014，Vo1．3．1．．临床研究·不同浓度罗哌卡因用于超声引导下肌间沟臂丛神经阻滞的麻醉效果文四成陈潜沛欧阳天纬李夏桃麦武军【摘要】目的比较不同浓度罗哌卡因用于超声引导下肌问沟臂丛神经阻滞的麻醉效果。方法拟行上肢手术患者6O例，随机均分为A组、B组和C组，采用超声引导下肌间沟臂丛神经阻滞，A组、B组和C组分别给予0．3、0．4、0．5的罗哌卡因3Oml。观察并评价注药后15、30min臂丛各主要神经的痛觉阻滞效应、运动阻滞程度，记录麻醉效果、麻醉维持时间、运动阻

2、滞恢复时间。结果注药后15minA组、B组和c组各神经痛觉完全阻滞例数依次递增，c组肌皮神经、桡神经、正中神经和尺神经完全阻滞例数明显多于A组(P

3、因3Oml用于超声引导下肌间沟臂丛神经阻滞麻醉，均可达到理想的臂丛神经阻滞效果，随着浓度增加，麻醉起效加快而阻滞持续时间延长。【关键词】罗哌卡因；超声引导；肌间沟；臂丛；神经阻滞Clinicalobservationoilinterscalenebrachialplexusblockbyultrasound-guidedwithropivacaineofdiffer—entconcentrationsWENSi-cheng，CHENOiaft·pei，OUYANGTian-wei，LJXia—tao，MAIWu—jun．DepartmentofA
