Multichannel auditory brain stem response (ABR) recordings were obtained in 75 acute, severely brain injured patients. The purpose of the study was to assess, in patients with varied neuro-otologic pathology, the clinical feasibility and value of measuring the ABR simultaneously with more than one electrode array. The use of alternative electrode arrays, in addition to the conventional (vertex to stimulus ipsilateral ear) array, augmented confident identification of wave components I through VI, and was particularly useful in patients with marked middle ear pathology which confounded ABR interpretation. The ABR recorded with an indifferent (noncephalic) reference electrode, e.g., was characterized by increased Wave V amplitude, and improved definition of Wave IV vs. V. Case studies are presented to illustrate neuro-otologic applications of the multichannel recording technique.
对75例急性重度脑损伤患者进行了多通道听性脑干反应（ABR）记录。本研究的目的是评估在患有不同神经耳科病理状况的患者中，使用不止一个电极阵列同时测量ABR的临床可行性和价值。除了传统的（头顶至刺激同侧耳）电极阵列外，使用替代电极阵列增强了对波成分I至VI的可靠识别，并且在中耳病理状况明显而混淆ABR解读的患者中特别有用。例如，用无关（非头部）参考电极记录的ABR的特征是V波振幅增加，以及IV波与V波的清晰度提高。本文通过病例研究来说明多通道记录技术在神经耳科的应用。
