Abstract
We investigated in an in vitro transfusion model the early effects of plasma preparations and donor red blood cells on the antioxidant capacity of the cord blood from babies. Addition of pasteurized plasma protein solution to plasma from babies decreased the peroxyl radical trapping capacity (p < 0.02). In contrast, fresh frozen plasma did not lower this capacity. Addition of adult donor red blood cells to the babies' red blood cells did not significantly decrease the glutathione-recycling capacity of the blood. On the basis of these in vitro results we hypothesize that the use of resuscitation fluids with low antioxidant capacity may temporarily decrease the ability of the baby to catabolize reactive oxygen species.
