Four patients who fulfilled all the clinical criteria for brain death, and 17 patients who did not, were tested with brainstem auditory evoked responses (BAER). Of the brain-dead patients, 3 had no waves present in the BAER, including wave. I. Initially BAER were intact in none of the brain-dead patients and then showed a decrease in amplitude and a prolongation of latency of the later components (7 cases) until finally wave I alone was present (6 cases). Normal data suggested toxic or metabolic comatose patients (2 cases). BAER are an objective measure of one of the sensory pathways traversing the brainstem and can be used to evaluate the functional states of the brainstem in patients in whom brain death must be considered. The association of short-latency somatosensory evoked responses (SER) has greater clinical utility in the brain death setting because it is important to have a wave present which establishes that the input signal has reached the central nervous system.
对4名符合脑死亡所有临床标准的患者和17名不符合标准的患者进行了脑干听觉诱发电位（BAER）测试。在脑死亡患者中，3例BAER无波形，包括I波。最初，所有脑死亡患者的BAER均正常，随后部分患者（7例）后期成分的波幅降低、潜伏期延长，最终仅余I波（6例）。正常数据提示为中毒或代谢性昏迷患者（2例）。BAER是对一条穿越脑干的感觉通路的客观测量，可用于评估必须考虑脑死亡的患者的脑干功能状态。短潜伏期体感诱发电位（SER）与之联合应用在脑死亡诊断中具有更大的临床实用性，因为存在一个能确定输入信号已到达中枢神经系统的波形很重要。
