摘　　要：本文对78例重度颅脑损伤患者行临床格拉斯哥评分(GCS)、颅内压(ICP)及脑干听觉诱发电位(BAEP)检查.以研究创伤性脑水肿时的GCS、ICP与BAEP间的关系.结果发现,CCS 8分上下组的ICP在4 kPa上下的比率显然不同(P<0.05),ICP在 4 kPa上下的BAEP异常率分别为39.53％和 82.86％(P<0.05),当ICP≥4 kPa时,BAEP异常率显著增加,提示创伤性脑水肿时,GCS、ICP、BAEP是同步变化,说明神经生理BAEP的变化与生物物理改变有内在关系.This paper studied the relations among ICP.GCS and BAEP in 78 cases with traumatic brain edema adimitted in our hospital from June 1990 to Feb 1993.There were 52 males and 26 females.Age ranged from 9 to 68 years.The result showed that the abnormal brainstem auditory evoked potential (BAEP) could reflect the severity of cerebral edema in acute head injury and had some relationships with intracramial pressure (ICP) when ICP>4 kPa,the abnormality of BAEP figure more obviously compared to controls (P<0.05).while in the patients with ICP over and below 4 kPa,the rate of abnormal BAEP were 38.46% and 77.78% respectively (P<0.05).With the recovery of ICP after treatment,the BAEP normalized in succession.The results indicate that BAEP may denote some indirect evidences for the relevant biophysical changes following the traumatic brain edema.The BAEP examination may provide an important clinical index in judging traumatic brain edema.
