摘要 目的 分析皮层体感诱发电位(somatosensory evoked potential,SEP)在颈椎病前后路联合 手术中的监护及判断颈椎病预后的价值。方法 对60例颈椎病患者前后路联合手术进行术中SEP 监护,分析患者手术前、后的JOA评分及术前、术中、术终及恢复期的SEP变化,了解SEP变化与神 经功能恢复之间的关系。结果 15例(30.0%)术中潜伏期缩短或波幅增大,以上病人术后脊髓功能 恢复良好,26例(52.0%)术前、术中、术终几乎无变化,8(16.0%)术中波幅有轻度下降,潜伏期轻度延 长,术终又恢复到接近术前水平,1例(2.0%)术中有波幅下降和潜伏期延长,术后症状加重。术后随 访SEP有潜伏期缩短或波幅明显增高的患者,临床症状改善明显。结论术中SEP的变化与患者的 脊髓功能恢复有一定的关系。SEP可以作为颈椎病前后路联合手术的监护及预后判断的指标。
