Abstract
OBJECTIVE: To analyse impact of delayed cord clamping (DCC60sec) on cerebral regional tissue oxygenation (crSO2) and fractional tissue oxygen extraction (cFTOE) in spontaneously breathing preterm neonates during the first 15 min after birth. METHODS: Two-centre observational study, crSO2 and cFTOE was monitored in neonates with DCC60sec or early cord clamping (ECC < 30 s). RESULTS: Seventy-six infants (birth weight and gestational age 1736 ± 508 g and 31.8 ± 2.5 weeks) were included. DCC was associated with lower initial crSO2 and higher cFTOE and lower initial Apgar-score and heart rate. CONCLUSION: Attending practitioners should be aware that DCC might impact initial immediate transition in spontaneously breathing preterm neonates.
