摘　　要：作者对急性颅脑损伤病人70例应用脑干听觉诱发电位(BAEP)就伤情评价和预后判断做了初步研究。对 BAEP 的异常按照 Greenberg 等的方法分Ⅳ级。结果表明,BAEP 级别与 GCS 记分呈负相关(r=-0.69),BAEP 级别越高,GCS 记分可能越低,临床状态则越差。本组原发和继发脑干损伤病人在 BAEP 疫常程度上无显著性差异。但在原发脑干损伤的诊断上可提高其可靠性。不同病期测定 BAEP 提示Ⅱ、Ⅲ级者最易发生变化,改善者占71.43%和35.71%,变化率为7.14和21.43,说明对这类病人应密切观察,反复监测。BAEP 级别越高,病人预后可能越差。70 patients of head-injury were studied with brainstem auditory evoked potentials (BAEP) for the evaluation of patient condition and progn osis. Abnormal BAEP's were divided to4 groups according to Greenberg's method. The results indicated that BAEP grades were negatively correlated with GCS score (r=-0.69).The higher BAEP grades,the less GCS score and the more seriousness of the trauma would be.There is no significatly difference for abnormal BAEP be ween primary and second brain-injury.BAEP could increase the accuracy on diagnosis of primary brainstem injury Dynamic value of BAEP suggest that Group Ⅱ prognosis Ⅲ changed the easiliest close attention should be paid to these patients and dynamic change in BAEP showed be mon itored.The higher BAEP group,the poor prognosis
