Red Cell Rejuvenation for the Attenuation of Transfusion Associated Organ Injury in Cardiac Surgery

The rejuvenation process involves incubation of stored red cells with a rejuvenating solution, rejuvesol Red Blood Cell Processing Solution (rejuvesol® Solution), Citra labs, MA, a Zimmer Biomet Company, IN, USA) which restores red cell adenosine triphosphate (ATP), 2,3-DPG (diphosphoglycerate), oxygen transfer characteristics and rheology. Post rejuvenation red cells are washed to remove the rejuvesol Solution, and cells are re-suspended in additive solution for transfusion.

Allogeneic red cells, harvested in citrate-phosphate-dextrose (CPD), leucocyte depleted, saline-adenine-glucose-mannitol (SAGM) stored red cell units, issued by National Health Service Blood \& Transplant (NHSBT) will be administered to cardiac surgery patients as per standard practice, and according to established unit protocols.
