Early vs. Delayed Cord Clamping at Full-Term Planned Cesarean Section: A Randomized Study

Objective: In cesarean section (CS), which, early vs. delayed cord clamping is better for neonatal and maternal hematocrit/hemoglobin level is not yet completely determined. This randomized controlled study attempted to determine this issue. Methods: Study population consisted of 64 full-term pregnant women/neonates undergoing planned CS: 32 received early cord clamping (ECC: 15 seconds after birth) and 32 delayed cord clamping (DCC: 90 seconds). We measured and analyzed 1) neonatal hematocrit at the first 24 - 48 hours, and 2) maternal-hemoglobin-change before and after CS. Results: Infants with ECC and DCC showed hematocrit (24 - 48 hours) of 57.47 ± 8.65 vs. 59.54 ± 7.67, showing no significant difference. Also, no significant differences were observed in the change in maternal hemoglobin in two groups. Conclusions: Cord clamping at 15 vs. 90 seconds did not yield neonatal hematocrit change or maternal hemoglobin change. As far as the present data (neonatal and maternal anemia) was concerned, cord may be clamped at 15 seconds in planned term CS.
