Background: the optimal timing of clamping of the umbilical cord after birth have been a subject of controversy and debate, However, there is insufficient evidence to date to support a recommendation as regards the impact of DCC on respiratory function in preterm neonates to delay cord clamping.
Aim of the work: this study aimed to evaluate the effect of deferred cord clamping on respiratory function in preterm neonates born vaginal.
Methods: The study was randomized controlled trial, including 100 Pregnant women (age 20-35 years old) had spontaneous preterm birth vaginal from 34-36⁺⁶ weeks, 50 subjected to ECC and 50 subjected to DCC.
Results: neonates in the two-randomization group differed significantly in requirement of O2 and ventilatory support, and neonates in the ECC group had a mean that was higher than neonates in the DCC group in both CPAP and nasal O2 (ECC 6 (12.0%) vs. DCC 1 (2.0%) – ECC 27 (54.0%) vs. DCC 18 (36.0%) in CPAP and O2 requirement respectively. Apgar scores at 1 and 5 min were significantly different in the two groups, and in general higher in DCC than ECC, reflecting better respiratory symptoms in group DCC.
Conclusion: the existing literature on delayed cord clamping has consistently demonstrated benefit especially for preterm neonates in facilitating placental transfusion. Improved physiologic stability in transition (blood pressure), better respiratory outcome, reduced need for transfusion is valuable improvements in outcome.
