[Rejuvenation of autologous blood preserved by washing in glucose- adenine- phosphate- and citrate-containing solution].

Outdated red cell concentrates (RCC-SAGM) were washed with a chloride-free, glucose-adenine-phosphate-citrate preservation solution. After resuspension of the red cells in this solution a hypothermic storage for additional 63 days was performed. Quality parameters (2,3-DPG, glucose, lactose, free hemoglobin, pH, chloride, pO50, shape quality index, filtration index) of the preserved red blood cells became normal within 7-11 days after the rejuvenation procedure. The data prove that a rejuvenation of outdated blood by a simple washing procedure allows a post-storage time of 21 days.
