Brief summary: This study was conducted to evaluate the effects of delayed cord clamping and milking the umbilical cord of term babies after 90 seconds during vaginal birth on the newborn and the mother and to determine whether it is a suitable alternative method for cord management after birth.

Methods: The study was conducted in the form of a randomized controlled design. The study was conducted in a hospital in eastern Turkiye between February -January 2025. The study was completed with 108 women who had vaginal delivery at term (DCC group n=36, UCM group n=36, control group n=36). Participants were assigned to groups by simple randomization. Data collection tools were used to collect demographic information, maternal hemoglobin, and hematocrit values, placental abruption time, newborn APGAR scores, umbilical cord pH levels, and day 7 hematological/biochemical parameters.

Detailed description: Labor and the postpartum period are critical periods that can have long-term effects on both maternal and neonatal health. Evidence-based interventions implemented during this period play a significant role in maternal physiological recovery, placental abruption, neonatal health parameters, and long-term health bilical cord management (delayed cord clamping \[DCC\] and umbilical cord milking \[UCM\]) has become an important research topic in recent years regarding its effects on maternal and neonatal outcomes DCC is defined by clamping the umbilical cord after birth for a certain period of time, and it has been shown that this practice can increase neonatal hemoglobin and hematocrit levels and reduce the risk of neonatal anemia . At the same time, it has been reported that DCC is especially recommended to reduce iron deficiency anemia in low-income countries . However, there are also views that DCC may prolong the time to placental abruption and increase the risk of postpartum hemorrhage in the mother UCM is defined as the process of pushing blood in the umbilical cord to the newborn with mechanical movement. There are studies indicating that this method improves oxygen transport by increasing blood volume and reduces the risk of intraventricular hemorrhage while increasing cardiovascular stability in premature babiesHowever, there are conflicting results in the literature regarding the effects of this method on hyperbilirubinemia and hemoglobin increase The effects of these different methods in umbilical cord management on maternal hemoglobin and hematocrit levels, placental abruption time, neonatal hematological and biochemical parameters, and postpartum complications have been an important area of research . Studies have emphasized that there are important relationships between the duration of placental abruption and neonatal health indicators and that these processes should be examined in detail . It has been reported that providing additional blood volume, especially in premature babies, can improve neonatological parameters and have important effects on maternal health . Therefore, studies have emphasized that the relationships between the duration of placental abruption and the timing of separation signs and neonatal health indicators should be examined in detail .In this study, many outcomes such as placental abruption time, maternal hemoglobin and hematocrit levels, and neonatal hematological and biochemical parameters were evaluated in this context. Therefore, this study aims to provide evidence to make a significant contribution to the literature on umbilical cord management practices and to determine the place of these practices in clinical practice.
