Delayed cord clamping

Real benefit to the baby, and one honest trade-off.

Across 15 trials and 3,911 mother-infant pairs at term, waiting to clamp the cord rather than clamping immediately:

OutcomeEffect of delayed clamping
Birthweight101 g higher (95% CI 45 to 157)
Infant hemoglobin at 24 to 48 hours1.49 g/dL higher
Iron deficiency at 3 to 6 monthsLess than half as likely (early clamping relative risk 2.65)
Severe bleeding for the motherNo significant difference (relative risk 1.04)
Need for phototherapy for jaundiceMore common with delayed clamping (relative risk 0.62 for early)

The reviewers concluded a more liberal approach to delaying clamping is warranted, as long as treatment for jaundice is available.

Ask for it in advanceSay it at a prenatal visit and have it written down. In a busy room the default is to clamp quickly.
