Concerns have recently been raised about the safety of transfusing stored-blood. Several studies have suggested that the risk of complications increases when transfused blood has been stored for long period. The liver is a target for injury in low flow states associated with trauma and hemorrhage. We studied the effect of blood resuscitation (fresh vs. Stored-blood) on liver injury. In rats, transfusion of blood stored longer than 4 days increased liver injury. This was associated with significant changes in the viscoelastic characteristics of the stored-blood and unrelated to the oxygen-carrying-capacity, cytokines in the stored-blood or the RBC/endothelial cells adherence properties.
