Umbilical cord milking versus immediate cord clamping

A randomized trial of infants born at less than 32 weeks gestation compared the effects of umbilical cord milking versus immediate cord clamping. Thirty infants were assigned to each arm. Infants who underwent umbilical cord milking had a higher serum hemoglobin, fewer blood transfusions, fewer days on oxygen therapy, and less frequent use of oxygen at 36 weeks postmenstrual age. They also had higher systemic blood flow (as assessed by superior vena cava flow and right ventricular output on echocardiography).
