听觉脑干诱发电位监测重型颅脑损伤

Auditory Brainstem Responses in Patients with Severe Head Injuries

３０例重型颅脑损伤行听觉脑干诱发电位（ＡＢＲ）检测，结果均异常。这种异常由轻到重的排列为波间潜伏期延长至各波均消失。本研究表明，ＡＢＲ分级与病情密切相关；ＡＢＲ检测能为脑干的功能状态提供客观资料，是诊断脑干损伤的可靠方法；ＡＢＲ检测对判断预后及脑死亡具有一定价值，其结果可作为脑死亡的判定标准之一。

Auditory brainstem responses(ABR)were recorded in 30 cases suffering from severe head injuries.Abnormal recordings were observed in all the patients,and the abnormalities ranged from prolongation of the interperk latency intervals to complete absence of all waves.Based on the results obtained,ABR grading system was considered to be correlated with the neurological outcome of head injuries.ABR could provide objective information about the function of the brainstem and predict brainstem dysfunction before the appearance of pupillary changing .ABR is a reliabe diagnosis and prognostic method for brainstem injuries,and is a diagnostic criteria of brain death as well.(Original article on page 33)
