[Coagulation problems associated with massive blood transfusions. An experimental study (author's transl)]
During storage banked blood show changes as far as function and concentration of their corpuscular and plasmatic ingredients are concerned. Antihaemophilic globulin (factor VIII) and pro-accelerin (factor V) in particular lose their activities so quickly that only very few activities still remain after a storage period of 3-5 days. In connection with existing primary diseases but also in trauma and shock a dilution-coagulopathy caused by insufficient supply of factors VIII and V can develop during massive transfusion, and this especially with banked blood already stored over a longer period of time. Therapy of this disturbance of coagulation consists of substituting the missing coagulation factors under heparin protection.
