【摘要】：目的探讨神经刺激器定位锁骨下臂丛神经后束与外束的临床效应。方法择期上肢骨科手术患者60例,年龄18~55岁,ASAⅠ~Ⅱ级,按照随机数字表法分成A、B两组,两组均定位喙突内下2 cm处,A组用神经刺激器诱发后束、外束,分别注入0.75%罗哌卡因与2%利多卡因混合液20 m L和10 m L。B组诱发后束支、外束支、内束支分别注入相同浓度局麻药各10 m L。记录给药后两组麻醉操作时间、感觉阻滞、运动阻滞情况。结果 A组麻醉操作时间、感觉阻滞起效时间、运动阻滞起效时间明显少于B组(P0.01)。A组感觉维持时间明显长于B组(P0.01)。两组运动阻滞维持时间没有明显差异(P0.05)。两组均未见明显不良反应。结论神经刺激器定位锁骨下臂丛神经后束与外束操作简单、安全,阻滞效果好,可以在临床选用。
[Abstract]:Objective to investigate the clinical effect of nerve stimulator on posterior and outer bundles of subclavian brachial plexus. Methods A total of 60 patients with upper limb orthopedic surgery, aged 18 to 55 years, were divided into two groups according to random digital table. The posterior and outer bundles were induced by nerve stimulator at 2 cm below the coracoid process in both groups. In group B, 0.75% ropivacaine and 2% lidocaine were injected with 20 mL and 10 mL respectively to induce posterior bundle branch, external bundle branch and internal bundle branch respectively. The anaesthesia operation time, sensory block and motor block were recorded. Results the operating time of anesthesia, the onset time of sensory block and the onset time of motor block in group A were significantly shorter than those in group B (P 0.01). Group A was significantly longer than group B (P 0.01). There was no significant difference in the maintenance time of motor block between the two groups (P 0.05). No obvious adverse reactions were observed in both groups. Conclusion the nerve stimulator can be used to locate the posterior and outer bundles of the subclavian brachial plexus.
