摘要(Abstract)：
[目的]脊柱术中体感诱发电位(somatosensory evoked potentials,SEPs)、运动诱发电位(motor evoked po-tentials,MEPs)监测受很多因素影响,当信号消失时一定要客观分析,避免假阳性,特别是假阴性带来的严重后果。[方法]一个先天性脊柱侧弯病例,行后路截骨侧凸矫形内固定术,术中行双下肢SEPs、MEPs联合监测。[结果]在截骨完成后10 min,双侧MEPs消失,双侧SEPs波幅下降>50%,潜伏期延长>10%,持续时间>90 mim,术中无唤醒,手术无暂停,术后患者神经功能正常。[结论]脊柱手术SEPs、MEPs联合监测有其敏感性和可靠性,但需及时准确鉴别其波形变化是否是假阳性或假阴性,这样,才能提高SEPs、MEPs监测的临床意义。
