title: [Current methods in blood preservation: recovery of blood components using a multi-bag system].
abstract: A new method of blood preparation by use of a multiple plastic bag system is prescribed. Buffy coat free red cell suspensions in additive solution (SAG-M), fresh frozen (recovered) plasma and random platelet concentrates can thus be produced. Apart from the so far clinically not instantaneously available stored platelets the storage time of the red cells is remarkably increased up to 42 to 49 days and the cellular contaminations (red cells and leucocytes in platelet concentrates, thrombocytes and leucocytes in FFP) are markedly diminished leading to a higher quality of these components. The Red Cross Blood Transfusion Service of Upper Austria presents its data obtained by the use of a quadruple plastic bag (RC Transfusion Production Center Eugendorf/Salzburg) with cellular contamination parameters far below the generally accepted limits. Apart from the increased quality of the components a very high level of clinical acceptance concerning especially the stored random platelet concentrates has been experienced. In conclusion the necessity of changing to a multiple bag system is strongly emphasized thus not only better fulfilling the clinical needs for the different blood components but also delivering higher qualities. Red cell preparations containing the buffy coat should therefore not be used any longer.
