Abstract
Purpose
This study aimed to compare the effects of early cord clamping (ECC), delayed cord clamping (DCC), and umbilical cord milking (MC) on maternal and neonatal outcomes in elective cesarean births.
Methods
We analyzed 204 women with uncomplicated at-term singleton pregnancies, who underwent cesarean birth under regional anesthesia between March and July 2021. The women were randomized into three groups: DCC (clamped 60 s postpartum), ECC (clamped within 15 s postpartum), or MC (clamped after milking five times) group. The neonatal and maternal outcomes of the groups were evaluated.
Results
The duration of the operation was significantly lower (P < 0.001) in the MC group at 50 min (ECC, 60 min; DCC, 60 min), while intraoperative bleeding was significantly higher (P < 0.001) in the ECC group at 500 mL (DCC, 300 mL; MC, 225 mL). The rates of anemia and polycythemia significantly differed (P = 0.049) between the three groups. DCC and MC did not negatively affect maternal and neonatal outcomes compared with ECC.
Conclusion
DCC and MC are superior to ECC in terms of short-term maternal and neonatal outcomes in cases of elective cesarean birth under regional anesthesia.
