目的 比较超声引导喙突处锁骨下臂丛神经阻滞与逆行锁骨下臂丛神经阻滞的临床麻醉效果.方法 拟行前臂或手部手术患者60例,随机分为两组,分别行超声引导下喙突处锁骨下臂丛神经阻滞(观察组)和超声引导逆行锁骨下臂丛神经阻滞(对照组),每组30例.记录麻醉成功率、麻醉操作时间、持续时间及并发症发生例数、各臂丛神经的起效时间.结果 对照组尺神经、前臂内侧皮神经起效时间较观察组短(P＜0.05).对照组有5例Homer's综合征,1例误入血管.结论 超声引导喙突处锁骨下臂丛神经阻滞和逆行锁骨下臂丛神经阻滞均是可行有效的区域麻醉方法.%Objective To compare the anesthetic effects between ultrasound-guided infraclavicular brachial plexus block via ooracoid approach and ultrasound-guided retrograde infraclavicular hrachial plexus block. Methods Sixty patient:, scheduled for forearm or kind surgery were equally randomized into two groups; infraclavicular brachial plexus block via coraeoid approach group (observation group) and retrograde infraclavicular brachial plexus block group (control group). The anesthesia success rale, performance time, duration time, the block onset time of brachial plexus, and the incidence of complication were recorded. Results There was no statistical significance in respect of the anesthesia success rate, performance time, and duration time. Compared wilh observation group, the block onset time of ulnar nerve and median antebrachial cutaneous nerve was shorter and the incidence of complication was higher in control group(P<0. 03). Concha-ion Infraclavicular hrachial plexus block via coraeoid approach and retrograde infraclavicular brachial plexus block by ultrasound-guided are feasible technique in regional anaesthesia, hut the block onset was slower and the incidence of complication was higher in ultrasound-guided retrograde infraclauicnar brachial plexus block.
