Sometimes prostaglandins, versions of chemicals the body naturally produces, are placed inside the vagina or taken by mouth to thin or soften (ripen) the cervix. Depending on the circumstances, the health care provider might use one of the following ways or a combination of them. There are various ways of inducing labor. That's because mother and baby can be monitored there, and labor and delivery services are readily available. Labor induction is typically done in a hospital or birthing center. If you have had a C-section and have labor induced, your health care provider is likely to avoid certain medications to reduce the risk of uterine rupture. The umbilical cord slips into the vagina before delivery (umbilical cord prolapse).You have an active genital herpes infection.Your baby is lying buttocks first (breech) or sideways (transverse lie).The placenta is blocking the cervix (placenta previa).You've had a C-section with a classical incision or major uterine surgery.Labor induction increases the risk that the uterine muscles won't properly contract after giving birth, which can lead to serious bleeding after delivery. Rarely, uterine rupture can also occur in women who have not had previous uterine surgery.Īn emergency C-section is needed to prevent life-threatening complications. This is a rare but serious complication in which the uterus tears along the scar line from a prior C-section or major uterine surgery. The longer the time between membrane rupture and labor, the higher the risk of an infection. Some methods of labor induction, such as rupturing the membranes, might increase the risk of infection for both mother and baby. The medications used to induce labor - oxytocin or a prostaglandin - might cause the uterus to contract too much, which can lessen the baby's oxygen supply and lower the baby's heart rate. In such cases, a C-section might be necessary. An induction might be considered failed if the methods used don't result in a vaginal delivery after 24 or more hours. Labor induction carries various risks, including: Low transverse incisions are the most common (top left). After the abdominal incision, the health care provider will make an incision in the uterus. It's important that women and their providers share in decisions to induce labor at 39 to 40 weeks.Ī C-section includes an abdominal incision and a uterine incision. Research shows that inducing labor at this time reduces several risks, including having a stillbirth, having a large baby and developing high blood pressure as the pregnancy goes on. In such cases, a health care provider will confirm that the baby's gestational age is at least 39 weeks or older before induction to reduce the risk of health problems for the baby.Īs a result of recent studies, women with low-risk pregnancies are being offered labor induction at 39 to 40 weeks. It can be useful for women who live far from the hospital or birthing center or who have a history of fast deliveries.Ī scheduled induction might help avoid delivery without help. These include heart, lung or kidney disease and obesity.Įlective labor induction is the starting of labor for convenience when there's no medical need. When the placenta peels away from the inner wall of the uterus before delivery - either partially or completely (placental abruption).Or having high blood pressure before pregnancy, developing it before 20 weeks of pregnancy (chronic high blood pressure) or developing the condition after 20 weeks of pregnancy (gestational hypertension). Developing high blood pressure in combination with signs of damage to another organ system (preeclampsia) during pregnancy.Possibly when diabetes develops during pregnancy (gestational diabetes), or diabetes exists before pregnancy.When there's not enough amniotic fluid surrounding the baby (oligohydramnios).When the baby's estimated weight is less than the 10th percentile for gestational age (fetal growth restriction).An infection in the uterus (chorioamnionitis).When labor doesn't begin after the water breaks (prelabor rupture of membranes).Nearing 1 to 2 weeks beyond the due date without labor starting (postterm pregnancy).They also include the baby's health, gestational age, weight, size and position in the uterus. These include the mother's health and the status of the cervix. To determine if labor induction is necessary, a health care provider will likely evaluate several factors.
