Preterm rupture of the amniotic fluid is known as preterm rupture of membranes, and it is possible to have a normal labor with preterm rupture of membranes. Factors that determine the possibility of a normal delivery include the force of labor, the birth canal, the fetus, and psychosocial factors. When these factors are normal and compatible, the fetus can be delivered normally through the vagina. When one of these four factors is abnormal, or they are not adapted to each other, an abnormal delivery may occur. Rupture of the membranes before labor is called premature rupture of membranes. In the case of premature rupture of membranes, the mode of delivery is determined by taking into account the week of gestation, the presence of chorioamnionitis, the ability of the fetus to tolerate contractions, and the position of the fetus. If there is no clear indication for cesarean section, a trial of labor can be performed vaginally. In full-term pregnancy, premature rupture of membranes, within 2-12 hours of rupture of membranes, labor is actively induced. If the cervix is ripe, induce labor with uterotonin; if the cervix is not ripe, induce labor with prostaglandin to promote cervical ripening. Premature rupture of membranes should be hospitalized in time, and the decision of whether to try vaginal delivery or cesarean section should be made according to the specific situation under the guidance of obstetricians. Monitor the condition of the mother and the fetus.
