神经刺激器定位静脉留置针臂丛神经阻滞的临床观察

目的：观察在神经刺激器定位下使用静脉留置针行肌间沟臂丛神经阻滞的可行性及效果。方法：自制一根用于将直型静脉留置针金属针芯尾部与神经刺激器负极连接的导线。选择60例臂丛神经阻麻醉下行上肢或锁骨手术的患者，随机分成留置针组和神经刺激器专用针组，每组30例，均采用肌间沟人路穿刺。记录定位时间、麻醉效果及相关不良反应。结果：两组的定位时间、麻醉效果及不良反应比较差异均无统计学意义。结论：静脉留置针用于神经刺激器定位下肌间沟臂丛神经阻滞麻醉具有可行性。

Clinical observation of venous indwelling needles on brachial plexus block under neurostimulator locating

Objective： To observe the feasibility and effect of using venous indwelling needles on interscalene brachial plexus block under locating of neurostimulator. Methods： A wire was made for connecting the tail of the metal needle core of the straight type of venous indwelling needles with the negative electrode of neurostimulator. 60 patients of brachial plexus block anesthesia for the surgery of upper limb or clavicle were selected to this study, and were randomly divided into the venous indwelling needle group and the dedicated needle of neurostimulator group, 30 patients in each group. The patients of both groups were punctured through interscalene approach. The location times, anesthetic effect and related adverse reactions were recorded. Results： For the location times, anesthetic effect and related adverse reactions, no statistically significant differences were found between the two groups. Conclusion： The venous indwelling needle for interscalenc brachial plexus block anesthesia under locating of neurostimulator is feasible.
