BackgroundIn Europe, red cell concentrates (RCC) are usually stored in SAGM (saline-adenine-glucose-mannitol). During storage, in vitro red cell quality declines, including lowered energy status and increased cell lysis. Recently, several additive solutions (ASs), designed to diminish the decline in in vitro quality during storage, have been developed. These new solutions have mainly been developed to better maintain red blood cell (RBC) 2,3-biphosphoglycerate (2,3 BPG) levels and energy status during storage. High levels of 2,3 BPG allow for better oxygen release while high energy status is necessary for function and survival of RBC in vivo. In a paired study design, RBC ASs were compared for their ability to provide improved in vitro quality during hypothermic storage.
