When labor progresses smoothly after the opening of the uterus by 10 cm, it takes less than 2 hours for a woman in labor to give birth and less than 3 hours for a woman in labor to give birth, but there are individual variations. When the uterine opening is 10cm, the uterine opening is complete and the second stage of labor begins, that is, from the opening of the uterus to the delivery of the fetus. When labor progresses smoothly, it takes less than 3 hours for primigravid women and less than 2 hours for experienced women to deliver their babies. However, when labor analgesia is administered, it should not exceed 4 hours for primigravid women and 3 hours for women in labor, and the progress of labor needs to be closely monitored. When labor does not occur for more than one hour after entering the second stage of labor, the descent of the fetal head needs to be adequately assessed, and when labor does not occur for more than two hours, the pelvis, fetal size, and descent of the fetal head need to be reassessed by an experienced physician, and a timely management plan is given, such as assisted vaginal delivery or cesarean section to terminate the pregnancy.
