躯体感觉诱发电位评价脑外伤预后

Somatosensory evoked potentials in head injury:prediction of outcome

目的 :探讨躯体感觉诱发电位 ( SEP)对判断脑外伤预后的临床意义。方法 :对 2 0例正常对象和 30例脑外伤患者监测 SEP的中枢传导时间 ( CCT) ,并采用 Glascow昏迷评分 ( GCS)评价患者的意识水平 ,患者出院或死亡时用 Glascow预后评分 ( GOS)评价预后。结果 :CCT( B)与 GCS、GOS均显著相关 ,CCT( W)、CCT( DIFF)与 GCS、GOS不相关。就判断预后的准确性而言 ,GCS+CCT( B)两者联用的准确性最高。结论 :SEP的

Objective:To assess the SEP inhead in jury:prediction of outcome. Method:Central conduction time in somatosensory evoked potentials(CCT) was recorded in2 0 normal subjects and30 patients with head injury.The level of conciousness was recorded with GCS.The patients′outcome were assessed when they were discharged or dead.Re- sults:The CCT(B) findings correlated well with Glascow coma score and Glascow outcom e score.With regard to the predictive accuracy,the combination of GCS and CCT is the best. Conclusion:SEP is effective in prediction of outcome of patients with head injury.
