What is arrest of active phase of labor?

Arrest of active phase of labor refers to a situation during childbirth where there is a prolonged halt in cervical dilation despite strong and regular contractions. Typically, this is defined as a lack of progress after six centimeters of dilation, lasting for two hours or more. This condition can necessitate medical intervention, such as cesarean delivery, to ensure the safety of both the mother and the baby. Factors contributing to this arrest can include the baby's position, uterine contractions, or maternal pelvic anatomy.
