Prolonged labor refers to a situation during childbirth where the labor lasts longer than expected. Typically, labor is considered prolonged if it exceeds 20 hours for first-time mothers and 14 hours for those who have given birth before. This can lead to increased stress for both the mother and the baby, and may require medical intervention. Several factors can contribute to prolonged labor, including the size and position of the baby, the strength of uterine contractions, and the mother's overall health. In some cases, healthcare providers may recommend interventions such as medications to stimulate contractions or a cesarean section if complications arise.
