Effects of timing of cord clamping on neonatal hemoglobin and bilirubin levels in preterm and term infants-A prospective observational cohort study.

DCC of ≥ 120 seconds appears to be optimal where hemoglobin and hematocrit are highest without an increase in the risk of neonatal hyperbilirubinemia. The risk of adverse effects like polycythemia or neonatal hyperbilirubinemia requiring phototherapy did not increase even after extending the time of cord clamping to >180 seconds.
