How long it takes to go into labor after the oxytocin injection depends on a variety of factors such as the patient’s sensitivity to the oxytocin, the number of pregnancies, the maturity of the cervix, the size of the fetus, etc. There are large individual differences. If a pregnant woman is sensitive to oxytocin and has a good cervical condition, a not too large fetus, good fetal position, good fetal tolerance as well as good labor, she can usually go into formal labor within 3 days. Some pregnant women may have contractions in 1-2 hours and regular abdominal pains in a few hours, leading to a successful delivery. In some other cases, there are no contractions even after the oxytocin injection, or the opening of the uterus is not progressively dilated, so it is impossible to determine how long it will take to deliver. Therefore, it is important to closely observe the progress of labor after giving oxytocin to induce labor. In the late pregnancy, pregnant women can take appropriate walks, do yoga exercises for pregnant women, learn about maternity science and familiarize themselves with the preparations before delivery and the precautions during delivery, which are very helpful for delivery.
