多种诱发电位评估急性昏迷病人的预后

Evaluation of the Prognosis of Acute Comatose Patients by Evoked Potentials

目的 研究诱发电位对急性期昏迷病人预后的价值。方法 180例患者在昏迷后第 1、3、7、10天进行脑干反射检查、GCS评分和多种诱发电位检测。结果 在昏迷第 1天GCS和脑干反射无预测价值 ,在第 1、3、7、10天GCS和脑干反射的预后准确率均低于 90 % ,各种诱发电位的预后准确率均高于 93 %。

Purpose: To evalute evoked potentials (EPs) as predictors of outcome in acute comatose patients. Methods: glasgow coma scale (GCS), brainstem reflexes and EPs examinations were performed on 1st, 3rd, 7th and 10th day in 180 comatose patients. Results: Neither GCS nor brainstem reflexes had prognostic value on 1st day. On 3rd, 7th and 10th day, GCS and brainstem predicted outcome with no more than 90% accuracy. EPs predicted outcome with more than 93% accuracy. Conclusions: Data from Eps were more accurate than GCS and brainstem reflexes as predictors of the outcome in acute comatose patients.
