[Clinical study of massive transfusions (108 cases)]

Amongst 108 surgical patients receiving massive transfusions, 60 died. Study of the aetiology of the haemorrhage, the circumstances of the transfusion, and the role of massive transfusions in the transmission of infectious diseases, disturbances in haemostasis, immunological, respiratory and metabolic complications led to the determination of certain simple criteria of gravity which may restrict their use:age over 60 years; the number of units used, if it exceeds 30; the existence of cirrhosis, of an acute lesion as the source of bleeding, or of peroperative haemorrhage. By contrast, the transmission of hepatitis, coagulation disturbances, immediate or delayed incompatibility accidents and variations in pH, blood potassium and calcium levels and arterial pO2 had little influence on mortality.
