Haematocrit in <35 weeks preterm infants who received at least 60 seconds of delayed cord clamping: a retrospective observational study.

Our study describes haematocrit in preterm infants who received ≥60 s DCC as standard of care. Haematocrit during the first 0-4 hours in our study is higher than the previously described reference ranges prior to DCC becoming routine clinical practice. The paired second haematocrit at 4-24 hours is higher than haematocrit at 0-4 hours.
