脊髓损伤中SEP的诊断价值

Diagnostic Value of SEP to Spinal Cord Injury

对７１例脊髓损伤患者入院时行短潜伏期体感诱发电位（ＳＬＳＥＰ）检测，根据电反应、潜伏期及波峰变化分为３组：Ⅰ组电反应正常；Ⅱ组各类波形异常；Ⅲ组完全无电反应。经过平均１４．５个月的随访（采用Ｆｒａｎｋｅｌ截瘫分级法），发现在５０例完全性截瘫患者中，ＳＬＳＥＰ无电反应者的截瘫恢复，手术组与非手术组无差异，而ＳＬＳＥＰ异常组手术后截瘫恢复明显优于非手术组。笔者认为，ＳＬＳＥＰ无电反应者无手术价值，而ＳＬＳＥＰ波峰及潜伏期异常则说明脊髓尚存留部分传导功能，均具有手术价值。

Seventy one patients with spinal cord injury received short latency somatosensory evoked potential (SLSEP) examination on admission. Based on the variations of the latent phase and the wave altitude, which were classfied as Ⅲ Groups:Group Ⅰ, the electrical response was normal, Group Ⅱ, there was some extent alteration in the wave altitude, and Group Ⅲ, the electrical response disappeared. After a average of 14.5 months, the recovery of the paraplegia had no significant difference in Group Ⅲ whether the patients were operated or not, and in Group Ⅱ, the recovery of the paraplegia in the operated patients was significantly superior to that in the non operated. The authors suggest that operation procedure is unavailable for the Group Ⅲ, but available for the Group Ⅱ.
