摘　　要：目的探讨体感诱发电位(SEP)、运动诱发电位(MEP)在脊髓髓内病变切除术中的应用价值。方法对22例脊髓髓内病变切除术患者术中采用SEP及MEP进行动态监测。结果与术前预警电位比较,患者术中SEP及MEP波幅多有降低(P<0.05),仅有6例SEP潜伏期延长,其余均没有明显改变;术毕SEP及MEP波幅均有所升高,而潜伏期无明显改善;术后随访3个月至3年,患者的症状和体征明显好转。结论脊髓髓内病变术中行SEP及MEP监测能有效降低神经功能机械性损伤,提高病变的切除率。Objective To explore application value of somatosensory evoked potential（SEP） and motor evoked potential（MEP） in surgical resection of intramedullary spinal cord lesions.Methods SEP and MEP dynamic monitoring were employed in 22 cases of patients with intramedullary spinal cord lesions during surgical resection.Results Compared with preoperative forewarning potential,most of cases of wave amplitude of SEP and MEP decreased during intraoperative monitoring（P〈0.05）,Only 6 cases of SEP latency lengthened while the others had no significantly changes;all wave amplitude of SEP and MEP increased after operation while latency with no obviously changes;3 months to 3 years follow-up showed symptoms and signs of patients improved markedly.Conclusion SEP and MEP monitoring during surgical resection of intramedullary spinal cord lesions can effectively reduce mechanically damage of nervous and increase successful resection ratio.
