肌电图仪在周围神经损伤手术中的临床应用

摘要

目的探讨肌电图仪在周围神经损伤手术中应用电刺激促进神经再生的监测作用。方法对23例周围神经损伤实施松解手术的患者于术中进行超强电刺激，在肌电图仪的持续监测下分析相应神经在刺激前后的电学变化。结果①电刺激后臂丛神经损伤和尺神经损伤复合肌肉动作电位的潜伏期较刺激前明显缩短，变化有统计学意义（P＜0.05）。②电刺激后臂丛神经损伤、正中神经损伤、桡神经损伤的复合肌肉动作电位波幅明显高于刺激前，变化有统计意义(P＜0.05)。结论肌电图仪在术中监测到对连续性尚存的损伤神经施行超强电刺激，能有效促进周围神经再生及神经功能恢复。%　　Objective Investigating the monitoring applications of EMG in surgery of the brachial plexus and peripheral nerve injury supramaximal electrical stimulation to promote nerve regeneration. Method Giving the supramaximal electrical stimulation to the 26 patients with brachial plexus and peripheral nerve injury who are given the release surgery in the continuous monitoring of the EMG, to analysis of the corresponding nerve electrical changes before and after stimulation and sensory and motor function recovery. Result ①Statistical significance brachial plexus injury group and ulnar nerve injury group before and after electrical stimulation compound muscle action potential latency change(P<0.05), stimulation is shorter than before stimulation.②It has statistical significance with before and after the electrical stimulation compound muscle action potential amplitude changes of brachial plexus injury group、median nerve injury groupand radial nerve injury group, (P<0.05), stimulation is higher than before stimulation. Conclusion Giving the supramaximal electrical stimulation in surgery can effectively promote peripheral nerve regeneration and recovery of neurological function for the injured nerves surviving in continuity.
