神经传导速度和H反射对酒精中毒性周围神经病的诊断价值

Significance of nerve conduction velocity and H-reflex in the diagnosis of chronic alcoholic peripheral neuropathy

目的:探讨神经传导速度(NCV)和H反射对慢性酒精中毒性周围神经病(CAPN)的诊断价值。方法:用肌电图检测CAPN患者50例和对照者50例。检测正中、尺、腓、胫神经的NCV,并在胭窝引出H反射。结果:CAPN组的NCV及H反射异常率分别为70%和92%,与对照组比较差异有极显著意义,下肢NCV异常率(82%)高于上肢的异常率(77%),感觉神经传导速度(SCV)异常率(84%)高于运动神经传导速度(MCV)的异常率(76%)。结论:NCV及H反射检测可作为酒精中毒性周围神经病变的检测手段之一。

Objective：To explore the diagnostic value of nerve conduction velocity（NCV） and H-reflex in patients with chronic alcoholic peripheral neuropathy. Methods： NCV and H-reflex were examined in 50 patients with chronic alcoholic peripheral neuropathy（ the patients group） and other 50 healthy subjects （the control group）. NCV of the madian , ulnar , peroneal and tibial nerves were measured and H-reflex was elicited by electromyography Results： A significant difference of NCV and H-reflex was noted between the patient＇s group and the control group. H-reflex and SCV were more sensitive than MCV . The abnormality rate of NCV and H-reflex in the patient＇s group was 70% and 92%. The abnormality rate of NCV in lower limbs was higher than that in upper limbs , and SCV was higher than that of MCV . Conclusions： Electromyography might be one of reliable.and sensitive diagnostic measures of chronic alcoholic peripheral neuropathy on the early stage.
