There is no exact time for delivery after the membranes are broken. Some women deliver within a few hours after rupture of membranes, but there are cases where labor does not proceed smoothly for more than 24 hours. Artificial rupture of membranes is a method of inducing labor. In natural labor, the membranes are normally broken at the end of the first stage of labor (near full opening), usually within 2 hours for primiparous women and within 1 hour for women in labor. If labor analgesia is administered, delivery is usually within 3 hours after rupture of membranes for primiparous women and within 2 hours for menstruating women. Usually, for those who do not deliver 12 hours after manual rupture of membranes, antibiotics should be given to prevent infection, and for those who do not enter the active phase after 12-14 hours of maintaining effective contractions before induction of labor is considered a failure. In addition, if the labor does not enter after 24 hours, a cesarean section should be considered. After artificial rupture of membranes, the pregnant woman should monitor the fetal heart sounds and observe the uterine contractions closely. In addition, pregnant women should pay attention to bed rest to prevent the umbilical cord from prolapsing and relax to avoid excessive tension.
