The examining results of SNAP, MAP and SEP of 239 median nerves and 76 ulnar nerves injuries are reported. Among those patients whose curative effects of complete severed nerves have reached "good" or above, SEP could be evoked in third month after suturing, MAP began to appear in sixth month and could be monitored in almost all patients in tenth month. On the other hand, SNAP was more difficult to evoke, only 2 cases could be recorded in tenth month, the figure came to about 80% after 4 years, and it could not be recorded in a few patients even after 10 years. While the clinical curative effects changed, the recovery rate of evoked potential changed accordingly. It has been proved the examination of evoked potential has important reference value to the diagnosis, treatment, regeneration and prognosis evaluation of peripheral nerve injury.
报告了239例正中神经损伤和76例尺神经损伤的感觉神经动作电位（SNAP）、运动神经动作电位（MAP）及体感诱发电位（SEP）的检测结果。在完全性神经损伤疗效达“良好”及以上的患者中，缝合后第3个月可引出SEP，第6个月开始出现MAP，第10个月几乎所有患者均可监测到MAP。另一方面，SNAP较难引出，第10个月仅记录到2例，4年后该比例达80%左右，甚至10年后仍有少数患者无法记录到。随着临床疗效的变化，诱发电位的恢复率也相应改变。已证明诱发电位检测对周围神经损伤的诊断、治疗、再生及预后评估具有重要参考价值。
