The decision of when a pregnant woman’s water breaks and when to deliver is based on the number of weeks of gestation. Gestational week reaches 34 weeks should be within 2~12 hours after the rupture of membranes actively induced labor, pregnancy less than 34 weeks, it is recommended to give the contraction inhibitor 48 hours, with the completion of glucocorticoids to promote the maturation of the fetal lungs after the treatment of labor, the specific existence of individual variability. 1. For those who have reached 34 weeks of gestation, if there is no clear indication for cesarean section, it is advisable to induce labor aggressively within 2 to 12 hours after rupture of membranes. For pregnant women with a ripe cervix, induction of labor with contractions is preferred. If the cervix is not mature and there is no contraindication to vaginal delivery, prostaglandin can be used to promote cervical ripening, and the mother and fetus should be closely monitored during the trial of labor, and it is advisable to terminate the pregnancy by cesarean section if there is a clear indication for cesarean section. 2. If the gestational week is less than 34 weeks, it is recommended to give uterine contraction inhibitors for 48 hours, with the completion of glucocorticoid treatment to promote fetal lung maturation, and at the same time should be timely prophylactic application of antibiotics, such as penicillin, roxithromycin, etc., which can effectively extend the gestational week to reduce the chorionic villous amnionitis and neonatal infections, and intrauterine transfer to the neonatal ICU of hospitals and then delivery. Once amniotic fluid rupture occurs, it is necessary to lie down immediately and elevate the buttocks to slow down the speed of amniotic fluid outflow, which can also prevent the occurrence of umbilical cord prolapse, and choose the appropriate mode and time of delivery under the guidance of the doctor in a timely manner.
