电生理检查对吉兰-巴雷综合征的临床价值

CLINICAL VALUE OF ELECTROPHYSIOLOGICAL DETECTION IN PATIENTS WITH GBS

目的 :探讨电生理检查对吉兰 巴雷综合征 (GBS)患者的临床价值。方法 :对 4 2例GBS患者进行周围神经传导速度、F波、EMG及电生理动态监测。结果 :GBS患者的运动神经传导速度、感觉神经传导速度减慢 ,末端潜伏期延长 ,波幅降低 ;F波出现率降低 ,潜伏期延长或消失 ;EMG表现为神经源性损害 ;电生理动态观察示 :临床症状改善早于神经电生理恢复 ,EMG明显异常者预后差。结论 :电生理检查对GBS的诊断、预后具有重要价值。

Objective:To explore the clinical value of electrophysiological detection for GBS.Methods:The peripheral nerve conduction velocity,F wave,EMG and electrophysiological changes were dynamically detected in 42 patients with GBS.Results: MCV and SCV retarded obviously,their amplitude fell and distal latency extended.The rate of F wave decreased.Electrophysiological observation showed clinical symptoms recovery was earlier than electrophysiological changes.Conclusion:Electrophysiological detection might be important in diagnosis and clinical prognosis of the GBS.
