对５０例儿童坐骨神经药物注射伤损伤部位以远的神经传导速度和波幅及体感诱发电位的结果分析并进行了相关的实验研究。在检查的５０例腓神经中有２７例引不出动作电位，４１例胫神经中有６例引不出动作电位。余２３条腓神经、３５条胫神经传导速度和波幅患侧均较健侧明显减慢和降低。同时对２３例患儿行体感诱发电位检查，结果表明患侧潜伏期较健侧明显延长。实验结果证实在损伤早期动作电位波幅的改变比传导速度的改变更明显，更有诊断价值。
The results of nerve conduction velocity and amplitude and somatosensory evoked potentials in 50 children with sciatic nerve injury caused by injection were analyzed and related experimental studies were carried out. In the examination of 50 cases of peroneal nerve in 27 cases can not lead to action potential, 41 cases of tibial nerve in 6 cases can not lead to action potential. The remaining 23 peroneal nerves, 35 tibial nerve conduction velocity and amplitude of the affected side were significantly slower than the contralateral and reduce. At the same time, 23 cases of children with somatosensory evoked potentials, the results show that the ipsilateral latency was significantly longer than the contralateral. The experimental results confirm that the change of the amplitude of action potential in the early stage of injury is more obvious than the change of conduction velocity, which is more valuable for diagnosis.
