This study is conducted to evaluate if the prone position of the newborn on the chest of his mother at birth before delayed cord clamping leads to better hematocrit and hemoglobin at 24-48 hours of life compared to supine position.

At 30 hours of life, laboratory personnel drew a capillary sample from the infant's heel for hemoglobin, hematocrit, and total serum bilirubin at the same time as the newborn metabolic screening sample. There is no added heelstick to routine care, as current standard in our institution requires the bilirubin to be drawn at 30 hours of life.

During universal screening for congenital cardiac defects (30 hours of life), a value of cerebral saturation (CrSO2) is measured using NIRS with INVOS (In Vivo Optical Spectroscopy, INVOS System, Covidien, Dublin, Ireland, Somanetics). Sensors are placed over the forehead and the newborn is in supine position.
