Abstract
Fetal red cells are well suited for intrauterine life; however, little is known about their response to postnatal environments. The purpose of this work was to investigate the metabolic and membrane changes affecting newborn red cells during their exposure to storage in citrate-phosphate-dextrose (CPD) and citrate-phosphate-dextrose-adenine (CPDA-1). The findings suggest that newborn red cells are affected more by storage than are adult cells. These accelerated storage changes in the red cells of newborns may be related indirectly to the rapid adenosine triphosphate (ATP) decline. As is the case with adult red cells, fetal cells withstand storage in CPDA-1 better than in CPD. The storage lesion in these cells was partly reversible, as in adult cells, by incubation with adenosine. It was therefore concluded that newborn red cells obtained from placentas and stored for several weeks in CPD or CPDA-1 media or other media that improve the metabolic profile of these cells may be acceptable for transfusion.
