A Five-Bag System for Washing Fresh and Frozen Erythrocytes and their Preservation

Abstract

A five-bag system was developed and tested. It allows to wash red blood cells three times under sterile conditions starting from whole blood and to store them by addition of a PDG preservation solution at 4°C for 2 weeks. In vitro and in vivo tests were performed. The system may be used also to wash and preserve prefrozen red blood cells.
