A pregnant woman’s water can be delivered within 48 hours after it breaks, but it varies from one pregnant woman to another. Some patients can deliver within a few hours, while a few patients with weak contractions or other abnormalities have a longer delivery time and may need a cesarean section if necessary. If a pregnant woman’s water breaks at home, her uterus may not be open at this time, so she needs to go to the hospital for delivery in time to avoid bacteria entering through the uterus and causing fetal infection or fetal lack of oxygen in the uterus. If the opening of the uterus is fast, the delivery time of the pregnant woman is also fast. If the contractions are weak or the fetus is too large, the labor may be slow and a cesarean section may be needed if the fetus is hypoxic. Sometimes the doctor will break the membranes manually after the delivery to speed up the dilatation of the uterus, so the delivery time may be faster. In short, once the water breaks, the pregnant woman and her family should first calm down, and then send her to the obstetrics department of the hospital as soon as possible, and get ready for delivery.
