Abstract
An additive solution, which can be dispersed in whole blood to enhance preservation of normal red cell morphology during storage, comprises a fatty ester which includes at least two ester linkages comprising fatty hydrocarbon groups of about four to twelve carbon atoms each. The solution can be introduced into the whole blood either at the outset of the storage period or any time during the period in an amount to provide, after its introduction, a concentration of the fatty ester of between 150 and 3,000 micrograms per milliliter of whole blood. When introduced at the outset of storage, morphological changes in the red cells are significantly retarded during the storage period. When introduced at later stages of storage, the solution serves to rejuvenate a significant percentage of red cells which have undergone morphological changes prior to the introduction of the solution.
