For both ‘vigorous’ term and preterm infants, ACOG recommends waiting at least 30 to 60 seconds after birth before clamping the umbilical cord. The committee opinion provides a comprehensive literature and evidence review. ACOG states
In term infants, delayed umbilical cord clamping increases hemoglobin levels at birth and improves iron stores in the first several months of life, which may have a favorable effect on developmental outcomes
Delayed umbilical cord clamping is associated with significant neonatal benefits in preterm infants, including improved transitional circulation, better establishment of red blood cell volume, decreased need for blood transfusion, and lower incidence of necrotizing enterocolitis and intraventricular hemorrhage
Benefits include
Note: There was no evidence for increased risk of PPH
Caution: The committee opinion notes that there may be a small risk for jaundice requiring phototherapy in term infants and therefore the delivery center should have the necessary infrastructure to monitor and treat, if necessary
When is delayed cord clamping not appropriate?
NOTE: ACOG states
Maternal hemodynamic instability or the need for immediate resuscitation of the newborn on the warmer would be an indication for immediate umbilical cord clamping
…cord milking should not be used for extremely preterm infants (less than 28 weeks of gestation)
…there is insufficient evidence to either support or refute umbilical cord milking in infants born at 32 weeks of gestation or more, including term infants
