BACKGROUND: Transfusion of blood products is the ideal resuscitative strategy after hemorrhage. Unfortunately, older packed red blood cells have been associated with increased morbidity and mortality after massive transfusion. These packed red blood cells accumulate biochemical and structural changes known as the red blood cell storage lesions. The effect of washing on the formation of red blood cell storage lesions is unknown. We hypothesized that washing packed red blood cells during storage would decrease the development of the red blood cell storage lesions. METHODS: Blood from 8- to 10-week-old male mice donors was stored as packed red blood cells for 14 days. A subset of packed red blood cells were washed with phosphate-buffered saline on storage day 7 and resuspended in AS-1 solution for an additional 7 days as washed packed red blood cells. Subsequently, the packed red blood cells were analyzed for microvesicle release, band-3 erythrocyte membrane integrity protein (Band-3), expression of phosphatidylserine, cell viability (calcein), accumulation of cell-free hemoglobin, and osmotic fragility. RESULTS: In the washed packed red blood cells group, there was less microvesicle accumulation, greater Band-3 expression, less phosphatidylserine expression, a decrease in cell-free hemoglobin accumulation, and a decrease in osmotic fragility, but no differences in red blood cells viability. CONCLUSION: Washing packed red blood cells during storage decreases the accumulation of red blood cell storage lesions. This strategy may lessen the sequelae associated with transfusion of older packed red blood cells.
