RÉSUMÉ
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
