[Value and worthlessness of clinical studies in the diagnosis of brain death].

Death was ever determined on the basis of extinguished partial functions of the entire organism (partial death). In intensive medicine with its possibilities of reanimation, with its possibilities of artificial maintenance of breathing and circulation the individual death of man is equated with his cerebral death. It comes only under conditions of reanimation and nearly always shows a clinically recognizable development. Practically above all "the syndromes in the forefield of cerebral death" are of interest as well as its obligatory and optional symptoms, the valency of which was critically tested. A 5-year-analysis (1969 to 1973) of 487 deaths in an internal intensive therapy unit (18% of mortality) was shown that causes, frequency and age distribution of the mortal conditions of disease as well as the average survival time of 4.5 days, in which cases, however, 43% of all deaths occurred within the first 24 hours, very rarely caused us to establish the irreversibility of the loss of the cerebral function on account of an organic dysfunction, but rather resulting from the question of the interruption of an absurd reanimation.
