There is no fixed time for the birth of a baby without regular contractions after the water breaks, and the exact time for the birth is related to the patient’s condition. The lack of regular contractions after water breakage is also clinically known as premature rupture of membranes, such as full-term premature rupture of membranes, for the safety of the mother and child, there is no clear indication of cesarean section, can be actively induced within 2 hours to 12 hours of rupture of membranes delivery; there are surgical indications, as soon as possible to perform cesarean section delivery. If the premature rupture of membranes occurs before full term, the fetus cannot survive if it is less than 24 weeks, and should be induced in time for delivery; if it is between 24 and 28 weeks, respect the wishes of the pregnant woman and her family, and decide the timing of induced labor according to the condition of the fetus; if there is no obvious contraindication for pregnancy, the pregnancy should continue from 28 to 34 weeks, and the patient should undergo the treatments of dynamic monitoring, promoting the maturation of the fetal lungs, and preventing the infections, and then choose a date for delivery. After rupture of membranes, pregnant women should receive standardized treatment under the guidance of professional physicians, so as to avoid delaying the condition and leading to adverse pregnancy outcomes.
