What is a common risk associated with macrosomic infants during delivery?

Macrosomic infants, those weighing more than 4,000 grams (approximately 8 pounds, 13 ounces) at birth, are at an increased risk of shoulder dystocia during delivery. Shoulder dystocia occurs when the baby's shoulder gets stuck behind the mother's pubic bone during delivery, which can lead to complications for both the infant and the mother. This is primarily because as the baby's size increases, the physical dimensions involved in a vaginal delivery become more challenging. When the baby's shoulders are larger than the pelvic inlet, it can cause a delay or difficulty in the birthing process.

In contrast, delayed cord clamping is typically considered beneficial rather than a risk, as it allows for improved blood volume transfer from the placenta to the infant. Shorter delivery times are generally associated with favorable outcomes and would not be a risk factor. Higher Apgar scores are indicative of better newborn health immediately after delivery and are not associated with risks of macrosomia.
