| Popis: | A 46-year-old man was diagnosed clinically brain dead after sustaining head trauma. The patient was in deep coma, brain nerves were unresponsive and spontaneous breathing was absent. However, EEG showed well preserved activity, but no reactivity to external stimuli. EEG activity disappeared within 40 h. BAEP were highly abnormal, flash-VEP as recorded 3 h after the diagnosis of brain stem death was of high amplitude but of simplified form. The neurophysiological findings revealed that the main reason for deep coma was brain stem damage while cortical activity was still present. This condition raises ethical questions when brain death is diagnosed clinically prior to removal of organs for transplantation. |
