A scoring system for diagnosis of DIC is proposed which encludes anam estic, clinical and laboratory criteria. From anamnestic criteria triwerinp event which lead to microeirculatory disturbances, like peripheral stasis (hysovolaemia, cardia; insufficiency) thrombin-inducers (septicaemia, haemolysis) and vascular damage (haemolytic-uraemic-syndrome, g ant haemangioma) score1 point as well as a positive etnanol gelation test. Clinical parameters include all organs which show sirns of a throrr. ho-haemormafic syndrom. They represent shock-orpans and can be diagnosed clinically by simultaneous appearance of bleeding symptoms and microthromrosis, like oliguria and haematuria (shock-orean kidney) or purpura and “Intravital death sports” (shock-orfran skin) or haemoptoe and hyaline membrane (shock-organ lunps). Laboratory parameters of DIC include the annearanee of helmet cells, of leuko- or neutropenia, of thrombocytopenia and of the demonstration of consumption coagulopathy (low F I, II, V, XIII) and of fibrinolysis (increased FDP, low plasminogen, low Antithrombin III). From our experience a score of 7 points or more is compatible with DIC.
