[Hepatic coma--causes, recognition, treatment]

The name of the disease coma hepaticum is a collective notion for etiologically, pathologo-anatomically and biochemically different kinds of a failure of the function of the liver. A demarcation of different forms of the liver coma is necessary above all for prognostic and therapeutic reasons: hepatic disintegration coma, coma in hepatic failure, mixed coma, false hepatic coma, ferment block coma. Despite certain progress the therapeutic possibilities in hepatic coma cannot satisfy in recent years. Also the use of different, partly very expensive methods of the so-called liver substitute (exchange function and plasmapheresis, heterologous and homologous extracorporal liver perfusion, parasymbiotic crossed circulation, haemoperfusion with encapsulated activated charcoal, liver transplantation) up to now did not lead to a decisive improvement of the nearly infaust prognosis of the hepatic disintegration coma. Therefore preventing measures and careful control of endangered patients deserve particular attention.
