A 25-year-old G1P0 delivers a 33 week infant vaginally. The delivery is uncomplicated. If the obstetrician wishes to optimize the outcome for the infant, the cord should be clamped
Delayed cord clamping of between 30 and 60 seconds is beneficial for pre term infants due to increasing total iron stores and hemoglobin levels, and decreasing the risk of intraventricular hemorrhage in the infants. Immediate bih outcomes such as Apgar scores, umbilical cord pH , or respiratory distress is unaffected by the timing of cord clamping. Delayed cord clamping also improves iron stores in term infants, but may also lead to a higher risk of hyperbilirubinemia.
Immediately
Between 30 and 60 seconds
After 60 seconds
Leave the cord unclamped until delivery of the placenta
