对49例格林—巴利综合征病人进行了肌电图、神经传导速度和F波测定,结果显示:运动传导速度正常或轻度减慢伴随诱发电位波幅的明显降低占57.6％,F波潜伏期轻度延长占32％,感觉传导速度轻度减慢占12％,感觉诱发电位波幅轻度降低占7％,失神经电位占71.4％。提示本组大多数病人与典型格林—巴利综合征不同,可能是格林—巴利综合征的一种亚型——急性运动轴索损害性多发性神经病。 Electromyography, nerve conduction velocity and F wave were measured in 49 patients with Guillain-Barre syndrome. The results showed that the motor conduction velocity was normal or mildly decreased with a significant decrease of evoked potential amplitude (57.6%). The F wave latency Mild extension accounted for 32%, sensory conduction rate slowed down slightly 12%, sensory evoked potential amplitude slightly reduced 7%, denervation potential accounted for 71.4%. Prompted that most of the patients in this group, unlike the typical Guillain-Barre syndrome, may be a subtype of Guillain-Barre syndrome - acute motor axonal detriment polycythemia.
