Abstract
The use of a gelatin plasma substitute as an integral part of a unified national program for the procurement of blood components and derivatives paves the way for the extensive use of red cell concentrates in the treatment of hemorrhage, the plasma from the original donations being partly diverted to the fractionation program of a national transfusion service. We estimated the potential of such a system paced by the demand for red cells and predicted that the use of 20% of fresh whole blood and 80% concentrates would not increase the demand for albumin, the yield of which would suffice to cover three‐quarters of current needs in our country. The actual performance of a program using 85% of red cell concentrates in a university hospital with an exceptionally high incidence of major hemorrhage was analyzed in detail. The use of albumin per unit of transfused red cells rose by 9%. With a nationwide increase of this magnitude, 67% of the demand in our country could still be met and the estimated true need for albumin of 200 kg per million inhabitants and year would be fully covered. The yield of factor VIII is 200–300% of the demand. The determinants of the effects of such a system vary from country to country, but its fundamental potential is obviously considerable.
