长期接触有机磷农药的生产工人,可有周围神经损伤。对上述工人需要有一种简便而有效的方法检查神经肌肉功能。如果发现有早期改变,应及早处理。理想的检查方法宜简便、无害、操作迅速而又经济。目前,英国及荷兰农药厂普遍用肌电图监测有机磷化合物对工人的影响。方法是在腕部给尺神经以单一超强刺激,于拇内收肌部位记录动作电位。于拇内收肌出现最大随意活动10秒钟后,重复上述刺激并记录、正常人对两次刺激的反应相等。故动作电位相同,从无附加的电位活动。有些正常人,第二个动作电位较高,这是由于随意活动促进了神经肌肉的传递作用,使复合的肌肉动作电位各成分更加同步化,故而总的波幅 Long-term exposure to organophosphorus pesticide workers may have peripheral nerve injury. There is a simple and effective way for these workers to check neuromuscular function. If you find any early changes, should be dealt with early. The ideal inspection method should be simple, harmless, fast and economical operation. At present, the British and Dutch pesticide plants commonly use EMG to monitor the effects of organophosphorus compounds on workers. Method is to the ulnar nerve in the wrist to a single super-strong stimulation, recorded in the thumb adductor position action potential. In the adductor adductis maximum voluntary activity 10 seconds, repeat the above stimulation and record, the normal response to two stimuli equal. Therefore, the same action potential, from no additional potential activity. Some normal people, the second action potential is higher, which is due to the voluntary activities to promote neuromuscular transmission, so that the compound muscle action potential more synchronized components, so the total amplitude
