摘要 目的探讨脊髓运动诱发电位(SCMEP)在椎管内肿瘤手术监测中的临床应用价值。方法对17例椎管内肿瘤患者采用手术中直接刺激脊髓后记录SCMEP,以电极安放后首次记录波形为对照,观察术中SCMEP的D1波的潜伏期和波幅,以前者>2ms、后者降低>20%为预警值。结果SCMEP由于病变部位及性质、刺激电极与记录电极间的距离不同,波幅及潜伏期的差异较大,电极安放后与手术结束时的结果个体对照,波幅部分增高,而潜伏期相差不显著。7例术中波幅降低超过预警值20%,经短暂休息或改变手术方向后,波幅恢复正常,避免了“假阴性”或“假阳性”结果的出现。结论作为一种新的监测技术,SCMEP对辅助医生进行手术安全操作、缩短手术时间、提高手术质量、减少术后神经功能障碍起到重要作用。
