摘要
目的：观察有机磷中毒患者的肌电图（EMG）、神经传导速度（NCV）改变。方法：对68例有机磷中毒患者进行常规EMG及神经传导检测。结果：纤颤电位出现率为32％，正向波出现率为37％；轻收缩时运动单位电位平均时限延长者占57％，波幅增高者占36％，多相波增多者占32％；重收缩时呈单纯相者占41％，混合相者占48％。感觉传导速度（SCV）异常者占24％，运动传导速度（MCV）异常者占60％，远端潜伏期延长者占37％。结论：EMG检查对有机磷农药中毒后迟发性神经病有重要诊断意义。有机磷农药中毒患者应及时进行EMG检查，以助于迟发性神经病的早期诊断及治疗。
Objective：To observe the changes of EMG and never conduction in patients with organ- phosphota induced neuropathy（OIN）. Methods： EMG examination was performed and nerve conduction was deterined in patients with OIN. Results.. The positive rate of fibrillation potential was 30 % and that of positive potential prolonged （57 % ） during light contraction, the amplitude increased by36 % and the mul- tiphasic potential increased by32%. The simple phase was 41% and the mixed phase was 48% in heave contraction. NCV determination showed the decrease of SCV （24% ） and MCV （ 60 % ）, and prolongationg of the distal latency. Conclusion：Electromyographic examination has important significance in the diagno- sis of organophosphate induced delayed neuropathy. Patients with OIN should be timely examined by elec- tromyography, which contribute to early diagnosis and treatment of organophosphate induced delayed neu- ropathy.
