The early and late components of the orbicularis oculi reflex were absent bilaterally in three patients who fulfilled the clinical and electroencephalographic criteria of brain death. A response to peripheral facial nerve stimulation was obtained in all. These preliminary observations suggest that the study of the orbicularis oculi reflex is a simple, objective, bedside neurophysiological test of brain stem function, complementing the electroencephalogram in the diagnosis of brain death.
三名符合脑死亡临床和脑电图标准的患者双侧眼轮匝肌反射的早期和晚期成分均缺失。所有人均获得了对面部周围神经刺激的反应。这些初步观察结果表明,眼轮匝肌反射研究是一种简单、客观的床边脑干功能神经生理学测试,可在脑死亡诊断中补充脑电图检查。
