Premature rupture of membranes refers to the rupture of the membranes before labor begins, causing amniotic fluid to leak periodically from the uterine cavity. Pregnant women with premature rupture of membranes can choose either vaginal delivery or cesarean section. Simply having a premature rupture of membranes is not an indication for cesarean section, but in some special cases of premature rupture of membranes, a cesarean section may be necessary. First, if the mother has previously had a cesarean delivery and experiences premature rupture of membranes in a subsequent pregnancy, a cesarean may be chosen; second, if the fetal position is abnormal, such as breech or transverse lies, after the rupture of membranes, a cesarean may be necessary; third, cesarean can be considered if fetal hypoxia occurs. For typical cases of premature rupture of membranes, a vaginal delivery can be attempted, but during the process, it is important to enhance fetal heart monitoring. If severe complications such as fetal hypoxia or placental abruption occur, it may be necessary to switch from vaginal delivery to cesarean section.
