Guillain-Barre综合征早期神经电图改变的临床分析

Significance of the change of electroneurogram in the early stage of Guillain-Barre syndrome

摘要: 目的: 探讨神经电图在Guillain-Barre综合征(GBS)早期的诊断价值。方法: 对16例GBS患者发病后2周内神经电图包括运动神经传导速度(MCV)、感觉神经传导速度(SCV)及F波结果进行回顾性分析。结果: MCV减慢占31.3%;末端潜伏期(ML)延长占28.1%;SCV减慢占25.0%;F波异常率87.5%。结论: 神经电图中F波是GBS早期诊断的敏感指标,尤其F波出现率降低更有诊断价值。

Abstract: Objective: To study the diagnostic value of electroneurogram in the early stage of Guillain-Barre syndrome(GBS).Methods: The electroneurograms of 16 cases with GBS,which involved motor nerve conduction velocity(MCV),sensory nerve conduction velocity(SCV)and F wave,were analyzed two weeks after the seizure.Results: MCV was slower in 31.3%,marginal latency(ML) was prolonged in 28.1%,SCV was slower in (25.0%).The abnormity rate of was 87.5%.Conclusions: The F wave abnormailty is a especially sensitive index in the early diagnosis of GBS.It has more diagnostic value;when less frequency of F wave occurs.
