Prospective Randomized Comparison of the Results of Early Clamping, Delayed Clamping and Milking of the Umbilical Cord in Term Cesarean Deliveries
Prospective Randomized Comparison of the Results of Early Clamping, Delayed Clamping and Milking of the Umbilical Cord in Term Cesarean Deliveries
The aim of this study is to show that delayed umbilical cord clamping or milking of the umbilical cord in pregnant women undergoing elective cesarean delivery might have better effects than early clamping, on neonatal results without causing maternal hemorrhage or negatively affecting the neonatal outcome , and to compare the superiority of these three methods to each other.
Late clamping of the umbilical cord has been shown to have positive effects such as higher neonatal hemoglobin level, higher iron stores in the newborn around three to six months, and better neurological development. In 2017, American College of Obstetricians and Gynecologists (ACOG) recommended a minimum 30-60 seconds delayed clamping of the cord after a minimum of 30-60 seconds, regardless of the delivery method, in both term and preterm newborns. In addition, optimal placental transfusion can be achieved due to strong uterine tonus in vaginal delivery. However, this is not possible due to decreased uterine tonus and time constraint in cesarean delivery. The main concern in delayed clamping and milking of the umbilical cord is the possibility of maternal anemia due to excessive maternal blood loss in the short term, the need for maternal blood transfusion or maternal intensive care support, and the possibility of conditions such as hyperbilirubinemia, symptomatic polycythemia, and long hospital stay that may cause the need for phototherapy in the newborn. Although there are many studies in the literature regarding the neonatal results of the clamping timing of the umbilical cord, there are a limited number of articles regarding the results in patients who underwent term elective cesarean section. The aim of this study is to show that delayed umbilical cord clamping or milking of the umbilical cord in pregnant women undergoing elective cesarean delivery might have better effects than early clamping, on neonatal results without causing maternal hemorrhage or negatively affecting the neonatal outcome , and to compare the superiority of these three methods to each other.
