[Massive transfusion].

Data about the definition of massive transfusion are given. The physiological changes during conservation of blood are reviewed and the effects of stored blood transfusion are stressed. The massive transfusion cases in 1979 are presented (in materials of five surgical departments) and the patient's condition during and after the massive transfusion analyzed. There was no correlation between volume of massive transfusion and frequency of complications during intensive therapy treatment. The group of patients transfused with transfusion pump showed better results.
