Cord clamping beyond 3 minutes: Neonatal short-term outcomes and maternal postpartum hemorrhage

Abstract

Background: Delaying cord clamping (CC) for 3-5 minutes reduces iron deficiency and improves neurodevelopment. Data on the effects of CC beyond 3 minutes in relation to short-term neonatal outcomes and maternal risk of postpartum hemorrhage are scarce. Methods: This was a prospective observational study performed in two delivery departments. Pregnant women with vaginal deliveries were included. Time to CC, estimated postpartum blood loss, and perinatal data were recorded. Spearman's correlation analysis and comparisons between newborns clamped before and after 3 minutes were performed. Results: In total, 904 dyads were included. The mean gestational age ± standard deviation was 40.1 ± 1.2 weeks. CC was performed at a median time of 6 minutes (range 0-23.5). Apgar scores at 5 and 10 minutes were positively correlated with time to CC (correlation coefficient.140, P
