Autologous umbilical cord blood for red cell concentrate transfusion in preterm infants in the era of delayed cord clamping: An uncontrolled clinical trial.

Objective: To assess the utility of autologous umbilical cord blood (UCB) for red cell concentrate (RCC) transfusion in preterm infants.

Methods: We recruited preterm infants born at ≤30 weeks' gestation or have an estimated fetal weight <1,200 g. We intended to perform delayed cord clamping (DCC) and to collect UCB following DCC.
