Labor Induction

For many pregnant individuals, labor does not begin on its own and requires medical assistance. Labor induction is the process by which a healthcare provider artificially initiates uterine contractions prior to the onset of natural labor.

The labor induction procedure is widely regarded as safe and does not carry an increased risk of cesarean delivery. However, the decision to induce labor is made carefully, weighing the clinical needs of both the pregnant individual and the baby.

Why Labor Induction May Be Recommended

Your provider may recommend inducing labor for a variety of medical reasons. Common indications include:

• You are past your due date (typically 41–42 weeks of pregnancy)
• High blood pressure or preeclampsia that poses a risk to both you and your baby
• Gestational diabetes with concerns about the baby’s health
• Fetal growth restriction (also called fetal growth restriction or FGR) when the baby is not growing as expected
• Premature rupture of membranes (also called premature rupture of membranes) when the amniotic sac breaks before labor begins
• Low amniotic fluid surrounding the baby
• Other medical conditions where continuing the pregnancy carries life-threatening complications

In some cases, elective induction may also be offered when you and your baby are healthy, and the benefits of scheduling delivery make sense for your individual situation.

Methods of Induction

We often combine several methods to help labor progress more effectively. The specific approach depends on your cervical ripening status (Bishop score), gestational age, and overall clinical picture:

Medications

Two of the most common medications used for labor induction are prostaglandins and oxytocin. Prostaglandins, such as misoprostol, are administered vaginally or taken by mouth to soften and open the cervix. This process, known as cervical ripening, prepares the cervix for labor and can also stimulate uterine contractions.

Once the cervix is ready, oxytocin, commonly known by the brand name Pitocin, is administered intravenously to induce uterine contractions and initiate labor.

Mechanical Methods

Several mechanical methods may also be used to facilitate labor induction. A balloon catheter, which consists of a small tube with an inflatable balloon, is inserted into the cervix and filled with water to gently encourage dilation. This method is frequently combined with medication to improve effectiveness.

Another mechanical approach is the artificial rupture of membranes, in which a provider uses a small instrument to break the amniotic sac, which can strengthen uterine contractions and advance labor. In many cases, a combined approach is employed, using more than one method simultaneously to facilitate labor as effectively and efficiently as possible.

Understanding the Risks

Induction of labor is generally very safe, but like all medical procedures, it carries some potential risks. Your healthcare provider will discuss these with you in the context of your specific situation:

• Uterine hyperstimulation
• Low fetal heart rate
• Umbilical cord prolapse
• Failed induction
• Uterine rupture
• Increased risk of infection

Important: Research consistently shows that induction of labor does not increase your risk of cesarean birth compared to expectant management. In fact, for some indications, labor induced at the right gestational age can improve maternal and neonatal outcomes.

How Long Does Induction Take?

Induction timelines vary widely from person to person. If it’s your first baby, the process typically takes longer than it would for someone who has given birth before. The condition of your cervix at the start of induction also plays a major role, since a cervix that is already softening and dilating tends to respond more quickly. The specific methods your care team uses to start or stimulate labor will further influence the pace, as will your gestational age and how well your cervix responds to ripening interventions along the way.

Pain Management Options

• Epidural: The most effective option, this can be administered at any time during the induction process. It has minimal effects on the fetus or labor progress and provides reliable, sustained relief.
• IV / IM Medications: As a moderate management tool, IVs are great short-acting medications. However, these are typically avoided during active labor due to potential effects on the baby’s heart rate.
• Nitrous Oxide: With mild-to-moderate pain management capabilities, nitrous oxide is breathed through a mask you control. Provides mild relief with minimal fetal effects.
• Natural Methods: For expecting mothers who are wary of medical intervention to pain, we can walk you through breathing, relaxation, massage, and position changes to manage discomfort during labor.

What Happens During the Induction Process

1. Cervical Assessment

When you arrive, your care team will perform a vaginal exam using a gloved finger to check how dilated, effaced, and positioned your cervix is. This information produces a Bishop score, which helps determine the best induction method for you. If your cervix is partially dilated, some methods may not be needed.

2. Cervical Ripening

If your cervix is not yet ready, the first step is cervical ripening. This may involve prostaglandins (misoprostol), a balloon catheter, or both. This phase can take several hours and is designed to prepare your uterus for active labor.

3. Starting Contractions

Once the cervix is ready, your provider may start labor using oxytocin (Pitocin) via IV, artificial rupture of membranes (breaking the amniotic sac), or a combination of the following methods. Uterine contractions will be monitored throughout.

4. Active Labor and Delivery

As labor progresses toward vaginal birth, your baby’s heart rate and your contractions will be continuously monitored. Your care team will keep your doctor updated throughout, and your doctor will be present for delivery. Most inductions result in a vaginal delivery.

What to Expect

When going through an induction, plan to stay in the hospital for the entire process, as it can take a significant amount of time. You are welcome to have two support people with you throughout. During this time, you and your baby will be monitored regularly using fetal heart rate and contraction monitors to ensure everything is progressing safely.

The induction process is initiated and managed by the resident team, and your attending doctor will be present for the delivery. At Maternal Fetal Medicine Associates, most patients who undergo an induction go on to achieve a vaginal birth.
