神经刺激仪定位在老年桡骨骨折手术患者行肌间沟臂丛神经阻滞麻醉中的应用价值

Application of nerve stimulator in patients with operation of interscalene brachial plexus block anesthesia in elderly fracture of radius

目的探讨神经刺激仪定位用于老年桡骨骨折患者行肌间沟臂丛神经阻滞麻醉效果。方法选择行肌间沟臂丛神经阻滞老年桡骨骨折患者100例,随机分为S组(50例)和P组(50例),分别在神经刺激仪和传统异感法定位下予罗哌卡因行神经阻滞,比较两组患者麻醉效果及满意度。结果 S组操作,臂丛感觉神经阻滞起效、完善及运动神经阻滞起效时间均短于P组,差异有统计学意义(P<0.05);S组麻醉满意度优于P组,差异有统计学意义(P<0.05)。结论神经刺激仪定位应用于老年患者行肌间沟臂丛神经阻滞,安全有效。

Objective To investigate the anesthetic effect of nerve stimulator method on patients with interscalene brachial plexus block in the elderly fracture of radius. Methods One hundred patients with elective upper limb operation of intermuscular groove brachial plexus block were chosen and randomly divided into 2 groups (n=50) including group S and group P. The patients in group S were treated with nerve stimulator interscalene brachial plexus block and those in group P with traditional paresthesia positioning method all by ropiva-caine. The the anesthetic effects and satisfaction of two groups were compared. Results The operation time, onset time and improving time of sensory nerve block of brachial plexus and the onset time of motor nerve block of brachial plexus of group S were significant shorter than those of group P. The anesthetic effects and satisfaction of group S were significantly better than those of group P. Conclusion The nerve stimulator can be safely and effectively applied in elderly patients with interscalene brachial plexus block.
