摘　　要：目的　观察慢性酒精中毒患者的神经电生理改变。方法　对 34例慢性酒精中毒患者进行常规肌电图及神经传导速度 (NCV)测定。结果　纤颤电位出现率 2 9.4 % ,正锐波出现率 31.6 % ;轻收缩时运动单位平均波幅增高 79.4 % ,时程增宽 72 .1% ,多项波 30 .9% ;重收缩时单纯相 2 6 .5 % ,混合相 5 7.4 % .感觉神经传导速度(SCV)减慢 4 2 .9% ;运动神经传导速度 (MCV)减慢 72 .5 % .结论　慢性酒精中毒可出现神经肌肉损害 。Objective To investigate changes of EMG and nerve conduction velocity in patients with chronic alcoholism.Methods Conventional EMG and nerve conduction velocity were carried out in 34 patients with chronic alcoholism.Results There were 29.4% of fibrillation potentials,31.6% of sharp wave potentials(MUPs);with slightly contraction,79.4% of amplitude and 72.1% of duration of motor unit potentials were increased,the polyphasic MUPs was 30.9%;with fully contraction,the single unit pattern was 26.5%,and interference pattern was 57.4%;sensory conduction velocity and motor conduction velocity decreased 42.9% and 72.5% nerves,respectively.Conclusion Chronic alcoholism might result in muscle and nerve injuries,particularly in distal parts.
