Effects of umbilical cord clamping time on perinatal outcomes

The aim of this fellowship thesis is to examine the maternal and neonatal effects of the clamping time of the umbilical cord. Ninety eight term pregnancies delivered by cesarean were included in the study. These cases were divided into two groups according to the cord clamping time after cesarean delivery. The cord clamped within the first 30 seconds after birth were group 1 and the clamped at 60th second were grouped group 2. Demographic characteristics and obstetric outcomes of all cases included in the study were evaluated. Maternal blood parameters were evaluated before delivery and fetal blood parameters were evaluated after cord clamping and compared between the two groups. In addition, at the 24th hour postoperative blood samples taken from the mother and baby and the need for phototherapy in the neonatal period were evaluated and compared between the groups. No significant difference was observed between the groups in terms of maternal and fetal blood parameters. There were 2 (3%) cases in group 1 who needed phototherapy and 7 (14.8%) cases in group 2. There was no statistically significant difference between the two groups in terms of the need for phototherapy in the neonatal period (p: 0.062). As a result, we observed that delaying the cord clamping time to 60 seconds after delivery is not related to adverse maternal results and especially fetal adeverse outcomes such as the need for phototherapy and polycythemia.
