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臂丛神经阻滞麻醉的临床效果。方法:50例拟行臂、腕、手掌及手指部位手术的患者,随机分为两组,每组25例。I组采用外周神经刺激器定位,当刺激到桡神经、正中神经、尺神经、肌皮神经时分别予以阻滞;组采用异感定位。两组均采用锁骨上入路,局麻药均为0.375%罗哌卡因。结果:使用神经刺激器组对尺神经阻滞的有效例数及麻醉成功率明显高于异感定位组(P<0.05),麻醉起效时间、痛觉消失时间均短于异感定位组(P<0.05)。二者在实施阻带时间、镇痛持续时间及运动阻滞时间比较差异无统计学意义(P>0.05)。结论:采用0.375%罗哌卡因经外周神经刺激器行锁骨上入路臂丛神经阻滞定位更精确,阻滞成功率高,是一种安全、可靠的神经阻滞方法。
Objective： To compare the clinical ettects of brachlal plexus nerve block performed with peripheral nerve stimulator （PNS） or paresthesia technique. Methods：A total of 50 patients under surgery of the forearm, wrist and fingers were randomly assigned to two groups. In group I （ n =25）, the whole local anesthetic was injected after locating the median, ulnal, radial and musculocutaneous nerve by the peripheral nerve stimulator. In group I （n = 25）, when a parestesia was elicited, the whole local anesthetic was injected. 0. 375% ropivacaine was used as local anesthetic. Result：Analgesia of the ulnal nerve and the success rate of block was greater with PNS than with paresthesia technique. There were differences in the onset time, analgesia time of the 2 groups. But there was no difference in performing time, the duration of the analgesia and motor block time. Conclusion： For superclavical brachial plexus block, PNS is safer and has a greater success rate of block than the paresthesia technique.
