彩色多普勒引导下锁骨上臂丛神经阻滞在上肢骨科手术的应用

Application of ColorDoppler Ultrasound-guided S upraclavicular Brachial Plexus bloc k on Upper Extremity Operation

目的：研究彩色多普勒引导下锁骨上臂丛神经阻滞在上肢骨科手术的应用。方法：60例择期行上肢骨科手术患者，年龄20～40岁，ASAI～II级，手术部位包括前臂、肘部、手掌、手指，随机均分为A、B 2组，每组30例，均实施锁骨上臂丛神经阻滞：A组采用超声定位法，B组采用针刺异感定位法，阻滞完成后观察2组患者的麻醉效果评级，感觉阻滞评分，阻滞所用时间及并发症情况。结果：A组患者麻醉效果评级明显优于B组；A组患者感觉阻滞评分明显低于B组；A组完成神经阻滞所用时间较B组少；A组患者并发症发生情况明显少于B组，其中以手部感觉、运动异常及血管损伤为主；以上差异均有统计学意义（P＜0．05）。结论：将彩色多普勒超声引导下锁骨上臂丛神经阻滞应用于上肢骨科手术中能有效提高阻滞效果，减少阻滞所用时间，降低并发症的发生率。

Objective：To study the application of color doppler ultrasound -guided supraclavicular brachial plexus block on upper ex-tremity operation.Methods：Sixty patients, age from 20 to 40, ASA I-II, scheduled for selective upper extremity operation were ran-domly divided into two groups with 30 cases each .Group A and B received color doppler ultrasound -guided and neuro-stimulation supr-aclavicular brachial plexus block , respectively.After the block, observe the anesthetic effect scores , block scores, block time and compli-cations of both group .Results：Group A shows better anesthetic effect scores , lower block scores , less block time and less complications than group B.Conclusion：Application of color doppler ultrasound -guided supraclavicular brachial plexus block for upper extremity op-eration can improve anesthetic effect , reduce block time and complications .
