What is a significant risk associated with shoulder dystocia for the infant?

Shoulder dystocia is a critical obstetric emergency where the baby’s shoulder gets stuck behind the mother's pelvic bone during delivery. One significant risk associated with shoulder dystocia is the potential for cord compression. When the shoulder becomes impacted, it can lead to a situation where the umbilical cord is compressed between the baby's body and the mother’s pelvic bone. This compression can reduce blood flow and oxygen supply to the infant, which can lead to fetal distress and other serious complications. Therefore, understanding the risk of cord compression is crucial for managing shoulder dystocia effectively and ensuring the safety of the infant during delivery.

The other factors mentioned, such as breech position, labor duration, and postpartum hemorrhage, while pertinent to childbirth, do not specifically relate to the immediate risks posed to the infant during an episode of shoulder dystocia.
