吉兰-巴雷综合征患者肌电图及神经传导速度检测

目的：探讨吉兰-巴雷综合征（GBS）的电生理改变特点。方法：对32例GBS患者进行肌电图（EMG）、神经电图及F波检测。测定运动神经传导速度（MCV）、感觉神经传导速度（SCV）及末端潜伏期（Lat）和波幅（Amp）；测定F波最短潜伏期、出现率。结果：肢体神经远端潜伏期延长占53．7％，MCV减慢占68．7％。F波异常占91．8％，SCV减慢占64．4％，EMG提示神经源性改变占71．9％。结论：GBS为广泛的周围神经损害，神经肌电图电生理检测在GBS诊断中起着重要的作用，对于吉兰一巴雷综合征的诊断及预后具有重要价值。

ELECTROMYOGRAM AND NERVE CONDUCTION VELOCITY DETECTION IN PATIENTS WITH GUILLAIN-BARRE' SYNDROME

Objeetive： To explore the electroneurophysiological characteristics in patients with Guillain - Barre syndrome （ GBS ）. Methods： Motor conduction velocity （ MCV ）, sensory conduction velocity （SCV）, distal latency（Lat） and distal amplitude （Amp） as well as the shortest latency and the detection rate of F wave were measured in 32 patients with GBS diagnosed clinically. Results：In motor nerves examined, prolongation of the distal latency was found in 53.7%, reduction of MVC in 68.7%, F waves abnomality was noted in 91.8% , reduction of SCV in 64. 4%, EMG revealed neurogenic changes in 71.9%. Conclusion： GBS might result in widespread peripheral nerve damages. The electroneurophysiological detection might be the very important method for diagnosing GBS.
