Method for extending the useful shelf-life of refrigerated red blood cells by flushing with inert gas

摘要

Method using oxygen removal for extending the useful shelf-life of refrigerated red blood cells. A cost-effective, 4 DEG C. storage procedure that preserves red cell quality and prolongs post-transfusion in vivo survival is described. Preservation of adenosine triphosphate levels and reduction in hemolysis and in membrane vesicle production of red blood cells stored at 4 DEG C. for prolonged periods of time is achieved by removing oxygen therefrom at the time of storage; in particular, by flushing with an inert gas. Adenosine triphosphate levels of the stored red blood cells are boosted in some samples by addition of ammonium phosphate.
