What is the most common postpartum complication in mothers with higher-order multiples?

Postpartum hemorrhage is indeed recognized as the most common complication in mothers with higher-order multiples. The physiological demands placed on the body during a multiple pregnancy can lead to increased risks during and after delivery. In higher-order multiples, such as triplets or more, the uterus is significantly distended, which can result in an increased likelihood of uterine atony. Uterine atony, where the uterus fails to contract properly after delivery, is a primary cause of postpartum hemorrhage.

Additional factors that contribute to the risk of postpartum hemorrhage in these cases include the potential for prolonged labor, greater blood volume during pregnancy, and increased likelihood of needing interventions, such as cesarean delivery, which can also complicate the uterine's ability to contract.

While other complications like infection, depression, and high blood pressure can occur in postpartum mothers, they are generally not as prevalent as postpartum hemorrhage in those who have delivered higher-order multiples. Thus, understanding the risks associated with postpartum hemorrhage is crucial for managing care and ensuring the mother's health after delivery.
