摘要
目的 比较外周神经刺激器定位技术与异感定位技术用于锁骨上入路神经阻滞麻醉的临床效果。方法 48例拟行锁骨上入路臂丛神经阻滞的患者 ,随机分为两组 ,分别采用神经刺激器定位 (n =2 4)和异感定位 (n =2 4)方法 ,局麻药均使用0 5 %的罗比卡因。结果 使用神经刺激器组在起效时间、感差时间、痛觉消失时间均长于异感定位组 ,二者在运动阻滞时间和镇痛时间无显著性差异。但神经刺激器组神经阻滞麻醉成功率明显高于异感定位组。结论 采用 0 5 %罗比卡因配合神经刺激器行锁骨上入路臂丛神经阻滞是一种安全。
Objective To compare the clinical effects of brachial plexus nerve block performed with peripheral nerve stimulator(PNS)or paresthesia technique. Methods A total of 48 patients underwent surgery of the forearm, wrist and fingers were randomly assigned to two groups. In group I (n=23), the whole local anesthetic was injected after located by the peripheral nerve stimulator. In group Ⅱ(n=24), when a paresthesia was elicited, the whole local anesthetic (0 5% ropivacaine) was injected. Results There were differences in the onset time, hypoesthesia time, analgesia time of the 2 groups. But there was no difference in motor block time and the duration of the analgesia. The success rate of block was greater with PNS than with paresthesia technique. Conclusion Brachial plexus nerve block performed with PNS is safer and has a greater success rate of block than the paresthesia technique.
