Measure
Intervention Cell Recipients
Experimental: infusions: infants with moderate to severe hypoxic ischemic encephalopathy, begin cooling, and have autologous nucleated cord blood cells available for infusion will receive up to two infusions. Outcomes will be measured at 22-26 months by neurodevelopment assessment Infusion of autologous cord blood: Infants who meet study enrollment criteria will receive up to 2 infusions of their own volume reduced cord blood cells. The number of doses will be determined by the amount of available cord blood cells.
Placebo Recipients
Control: infants with moderate to severe hypoxic ischemic encephalopathy, begin cooling, and have cord blood available for infusion will receive placebo (a mix of autologous cord blood red blood cells and plasma) infusions. Outcomes will be measured at 22-26 months by neurodevelopment assessment Placebo: Infants who meet study enrollment criteria will receive up to 2 placebo infusions composed of an equivalent volume (volume of product that would have been administered if the infant randomized to the intervention arm) of packed red blood cells (PRBCs) from the red cell compartment of the separated cord blood unit.
