Summary

The investigators propose to compare the proteomic analysis of umbilical venous blood from neonates with brain injury to gestational age matched noninjured controls. After delivery an umbilical arterial gas and a 10 ml umbilical venous sample are obtained, then the remainder of the cord blood is discarded. The investigators plan to use this cord blood that would otherwise be discarded to perform our proteomic analysis. The investigators will use up to 20 ml of cord blood per delivery. This will be a 5 year study during which time the investigators hope to analyze 450 infants at Johns Hopkins Hospital and Bayview Medical Center. The investigators will obtain an umbilical venous sample from infants born at \< 34 weeks gestation. For infants born at \> 34 weeks the investigators will obtain an umbilical venous sample for any infant suspected to be at risk for neurologic injury by having a diagnosis of chorioamnionitis during labor, nonreassuring fetal heart rate tracing at the time of delivery, or a 5 minute Apgar \< 7. For the infants born at \< 34 weeks the brain injured infants will be compared to gestational age matched controls without brain injury. For the infants born at \> 34 weeks, each infant later confirmed to have neurologic morbidity will be compared to a gestational age matched noninjured control. The investigators hope to use proteomic analysis to determine if there are measurable differences in protein expression between the 2 groups.
