Routine Storage of Red Blood Cell Units in Additive Solution-3: a comprehensive investigation of the RBC metabolome

摘要

BackgroundIn most countries, packed red blood cells (RBCs) can be stored up to 42 days before transfusion. However, observational studies have suggested that storage duration might be associated with increased morbidity and mortality. While clinical trials are underway, impaired metabolism has been documented in RBCs stored in several additive solutions. Here we hypothesize that, despite reported beneficial effects, storage in additive solution-3 (AS-3) results in metabolic impairment weeks before the end of the unit shelf-life.
