糖尿病性周围神经病患者的神经电图改变

目的 观察糖尿病性周围神经病（DPN）患者神经电图的改变。方法 对78例DPN患者进行神经电图检查，包括运动神经传叶速发（MCV）、感觉神经传导速度（SCV）和F波检查。结果 共检查78例患者的468条神经，其中MCV减慢166条，MCV减慢合并远端潜伏期延长39条，异常率43．8％；SCV减慢175条，末引出电位75条，SCV减慢兼远端潜伏期延长26条，异常率58．9％．检查102条神经的F波，其中异常66条，异常率为64．7％，12条神经（11．8％）F波时间离散度增加。结论 神经电图是诊断DPN的敏感及特异性的检查，多个参数相结合有助于提高阳性检出率。

Changes of electroneurogram in patients with diabetic peripheral neuropathy

Objective To observe the changes of electroneurogram in patients with diabetic peripheral neuropathy(DPN).Methods The electroneurophysiological data of 78 patients with DPN,including motor nerve conduction velocity(MCV),sensory nerve conduction velocity(SCV) and F-response,were observed.Results Among the inspected 468 nerves of 78 patients with DPN,166 nerves' MCV were slowed down,and 39 nerves with the decrease of MCV were accompanied by the prolongation of distal delitescence.The abnormality rate was 43.8%.175 nerves' SCV were also reduced,75 nerves were tested with no potential elicited,and 26 nerves with the decrease of SCV were accompanied by the prolongation of distal delitescence.The abnormality rate was 58.9%.The F-waves of 66 nerves(64.7%) in 102 tested nerves were abnormal,and 12 nerves' F-wave time chronodispersion(11.8%) increased.Conclusions Electroneurogram is a sensitive and characteristic inspection in the diagnosis of DPN,and the diagnostic sensitivity may be improved if multiple parameters are used together.
