Changes in serum potassium in premature infants receiving packed red blood cells.
Changes in serum potassium in premature neonates undergoing transfusion from CPDA-1 triple satellite PRBC paediatric packs cannot be predicted solely on the basis of potassium dose and estimated plasma volume. Despite significant potassium loading during PRBC transfusion, the actual serum potassium change is much less than predicted in neonates with good renal status. These findings indicate that special washing procedures to reduce potassium concentrations in PRBC units for transfusion in neonates is not warranted although exclusion of units older than 5 days for transfusion in premature infants seems to be a reasonable policy.
