Generally, when the amniotic fluid breaks, labor can be spontaneous within 12 hours, but for premature rupture of membranes, the time required is longer and varies from person to person. If the amniotic membrane ruptures before delivery, it is called premature rupture of membranes. In the case of premature rupture of membranes near full term, the labor time is usually longer and may cause intrauterine infection and intrauterine pneumonia, so it is usually recommended to wait for 12 hours, and if labor persists, to give contractions to induce labor to start, and to try to end the pregnancy within 24 hours after the rupture of membranes for a smooth delivery. If the membranes rupture during labor, it is normal and labor usually occurs within 12 hours. After the rupture of amniotic fluid, you should lie flat in time, pay attention to elevating the hips and avoid actions that increase abdominal pressure to prevent the umbilical cord from prolapsing, which not only reduces the outflow of amniotic fluid, but also facilitates labor and effectively prevents bacteria from entering the uterus and infecting the fetus, while avoiding complications such as hypoxia. It is also necessary to rush to the hospital in time. The doctor will choose to deliver by cesarean section according to the condition of the pregnant woman, or use oxytocin to promote contractions to speed up delivery, or wait for normal delivery, but do not go out and walk around.
