摘要
目的比较传统异感法与神经刺激仪辅助定位法在臂丛神经阻滞中对运动与感觉阻滞的临床效果。方法选取行上肢手术的80例患者,随机分为对照组和观察组各40例,对照组采用传统异感法进行肌间沟臂丛阻滞,观察组在神经刺激仪引导下行肌间沟臂丛阻滞。比较两组患者麻醉后不同时间感觉和运动阻滞的情况。结果①观察组对于尺神经、桡神经、正中神经及肌皮神经组织效果均较好,两组患者在尺神经和正中神经阻滞效果上差异不明显,但观察组对桡神经和肌皮神经的阻滞效果明显优于对照组(P<0.05)。②两组患者麻醉后0.5 h、1 h、2 h、24 h疼痛评分差异不明显,6 h时观察组高于对照组(P<0.05);不同时间运动功能的恢复比较,观察组麻醉后1 h、2 h期间肌力超过2级的患者人数显著高于对照组(P<0.05)。结论神经刺激仪辅助定位法局麻效果更为肯定,可降低局麻药量,有利于术后恢复。
Objective To evaluate the clinical outcomes of motor nerve and sensory nerve separate block in interscalene bra-chial plexus block guided performed by nerve stimulator. Methods Eighty patients with upper extremity surgery were randomly divided into 2 groups with 40 cases each. The interscalene brachial plexus block was performed with the conventional technique in control group, and with a reformed method guided by the nerve stimulator in observation group. The sensory and motor block, VAS score and recovery of motor function were compared between the two groups at different time point after anesthesia. Results ①There were no significant differences in the outcomes of ulnar and medial nerve block. The success rate of musculo-cutaneous verve and radial nerve block was significantly higher in observation group than that in control group（ P 〈 0.05 ）. ②The VAS score of observation group was higher than control group at 6h after anesthesia（P 〈 0.05）. And the cases of myodynamia ≥ 2 in observation group were marked higher that in control group at 1 h and 2h after giving drugs （ P 〈 0.05 ）. Conclusion Brachi- al plexus block guided by the nerve stimulator is better than conventional technique with a higher block rate and lesser local anes-thetic dosage and faster recovery.
