The plasma collection system: a new concept in autotransfusion

We have used the Haemonetics Cell-Saver autotransfusion technique in over 6,500 cases since 1979, salvaging more than 11,000 units of packed red blood cells. Major utilization has been in cardiac, vascular, and orthopedic cases. Coagulopathy associated with hypothermia, shock, multiple transfusions, and the autotransfusion technique, which removes clotting factors and platelets, often necessitated use of fresh-frozen plasma and platelet packs postoperatively to control bleeding and clotting problems. However, this defeats the prevention of disease transmission, transfusion reaction, and autoimmunization. Haemonetics has recently developed a plasma collection system which salvages up to 1,000 cc of platelet-rich plasma. Early experience suggests this technique will not only decrease the incidence of postoperative bleeding but further decrease the use of homologous (bank) blood and components. A step-by-step guide to the plasma collection system is discussed. The plasma collection system augments the present autotransfusion technique that conserves red blood cells, thus making complete autologous blood transfusion a reality.
