Objective: We aimed to demonstrate non-inferiority of delayed cord clamping (DCC) and cord milking (CM) in comparison to early cord clamping (ECC) in the incidence of hyperbilirubinemia requiring phototherapy.
Material and methods: 467 of maternal-foetal dyads were screened for eligibility. 389 term infants, of breastfeeding, non-smoking mothers were randomized to receive ECC ( < 40 s), DCC (1-2 min) or CM (4 times towards the neonate). The primary outcome was defined as hyperbilirubinemia requiring phototherapy.
Results: 307 patients were included in the analysis. CM did not increase the risk of phototherapy RR 11.27 95% CI (0.80; 2.04). Similar results were achieved when comparing DCC and ECC, RR 1.29 95% CI (0.82; 2.05). This was also true for CM vs DCC, RR 0.99 95% CI (0.64; 1.52). The prevalence of total serum bilirubin (TSB) at 24-48 hours was 10.8 mg/dL; 10.33 mg/dL and 11.39 in ECC, CM and DCC group respectively. Transcutaneous bilirubin (TcB) levels at 24-48 h were 7.58 mg/dL, 7.89 mg/dL and 7.60 mg/dL in the ECC, CM and DCC respectively. None of the neonates met exchange transfusion criteria or symptomatic polycythaemia.
Conclusions: Our study suggests that placental transfusion is not associated with hyperbilirubinemia requiring phototherapy or exchange transfusion.
