[Reflexes in brain-dead patients].

Abstract

We report on a patient who suffered an acute, extensive intracerebral haemorrhage, leading to symptoms of cerebral herniation within a few hours. The clinical diagnosis of brain death was made based on a neurological examination, and an apnoea test eight hours after the haemorrhage. A few hours later the diagnosis was changed, as several reflexes reappeared. After six days mechanical ventilation was withdrawn, as the brain damage was considered so serious as to render further therapy futile. It was considered unethical to sustain therapy for a possible organ donation at a later date. A review of relevant the literature, however, shows that brain-dead patients may exhibit such varying degrees of autonomic and spinal reflexes as to cause confusion, thus delaying the physician in making a diagnosis. Often, an opportunity for organ donation is lost. Based on this review, we believe that our patient was indeed brain dead when the first diagnosis was made, and that a cerebral angiography should have been performed. Because organ donation is an important issue, the diagnosis of brain death must be definitive.
