When is it most critical to monitor uterine tone postpartum?

Monitoring uterine tone postpartum is particularly critical within the first 24 hours after delivery due to the heightened risk of uterine atony, which can lead to postpartum hemorrhage. During this initial period, the uterus is in the process of contracting to reduce size and expel any remaining placental tissue. Effective uterine contractions are essential to maintain a firm, well-contracted uterus, which helps prevent excessive bleeding.

After the first breastfeeding session, while monitoring may still be necessary due to the oxytocin released, it is not as critical as during the first 24 hours. The first week post-delivery is also important for monitoring, but specific attention to uterine tone is essential immediately postpartum when the risk for complications is at its highest. Similarly, monitoring at discharge visits is significant for overall maternal health but does not carry the same immediate urgency regarding uterine tone as in the first day post-delivery. Therefore, the focus on the first 24 hours emphasizes a proactive approach to detecting and managing any complications that may arise during this vulnerable time.
