The effect of cord clamping time on cord blood gas in term newborn babies delivered by cesarean section

Objective: Umbilical cord clamping time is a situation that should be planned before delivery. It recommended the umbilical clamped for at least 30–60 seconds after birth in healthy preterm and term newborns. There are few studies investigating effect of on blood gas. If 30 birth, it considered early clamping, if seconds, late clamping. In this study, we aimed to compare or with acid-base parameters lactate values babies. Methods: A total 217 newborn infants who were delivered by cesarean section between December 2020 2021 our hospital, whose times recorded had samples, included study retrospectively. pH, pCO2, pO2, HCO3, BE, lactate, Hb bilirubin gas samples compared two groups. Results: Two hundred seventeen babies study. Cord was delayed 125 (57.6%) 92 (42.4%) infants. The mean pH 7.37±0.07 (7.16–7.57), pCO2 39.73 ±8.97 (20.3–65.4) mmHg, pO2 53.42±41.95 (14.8–198) BE -2.18±2.90 (-11.9–13.6) mmol/L, 2.12±0.88 (0.50–5.90) 14.57± 2.54 (10–23.7) g/dl, 1.71±1.33 (0–3.7) mg/dl. Conclusion: no significant relationship parameters, hemoglobin section.
