Inducing Labor

Inducing Labor

It's common for many pregnant women, especially first-time mothers, to watch their baby's due date come and go without so much as a contraction. The farther away from the expected delivery date (called the EDD) you get, the more anxious you might become. You may start to wonder — is this baby ever going to come?

Late pregnancy can be challenging — you may feel large all over, your feet and back might hurt, you might not have the energy to do much of anything, and you're beyond ready to meet the little one you've nurtured all this time. Which is why waiting a little longer than you'd expected can be particularly hard.

Still, being past your due date doesn't guarantee that your doctor (or other health care provider) will do anything to induce (or artificially start) labor — at least not right away.

What Is It?

Labor induction is what doctors use to try to help labor along using medications or other medical techniques. Years ago, some doctors routinely induced labor. But now it's not usually done unless there's a true medical need for it. Labor is usually allowed to take its natural course. However, in some situations, a health care provider may recommend induction.

Why It's Done

Your doctor might suggest an induction if:

Induction also can be appropriate under certain circumstances, as with a mother who is full term and has a history of rapid deliveries or lives far from a hospital.

Some mothers request elective inductions for convenience, but these do come with risks. Doctors try to avoid inducing labor early because the due date may be wrong and/or the woman's cervix might not be ready yet.

How It's Done

Some methods of induction are less invasive and carry fewer risks than others. Ways that doctors may try to induce labor by getting contractions started include:

What Will It Feel Like?

Stripping the membranes can be a little painful or uncomfortable, although it usually only takes a minute or so. You may also have some intense cramps and spotting for the next day or two.

It can also be a little uncomfortable to have your water broken. You may feel a tug followed by a warm trickle or gush of fluid.

With prostaglandin, you might have some strong cramping as well. With oxytocin, contractions are usually more frequent and regular than in a labor that starts naturally.

Risks and Precautions

Inducing labor is not like turning on a faucet. If the body isn't ready, an induction might fail and, after hours or days of trying, a woman may end up having a cesarean delivery (C-section). This appears to be more likely if the cervix is not yet ripe.

If the doctor ruptures the amniotic sac and labor doesn't begin, another method of inducing labor also might be necessary because there's a risk of infection to both mother and baby if the membranes are ruptured for a long time before the baby is born.

When prostaglandin or oxytocin is used, there is a risk of abnormal contractions developing. In that case, the doctor may remove the vaginal insert or turn the oxytocin dose down. While it is rare, there is an increase in the risk of developing a tear in the uterus (uterine rupture) when these medications are used. Other complications associated with oxytocin use are low blood pressure and low blood sodium (which can cause problems such as seizures).

Another potential risk of inducing labor is giving birth to a late pre-term baby (born after 34 and before 37 weeks). Why? Because the due date (EDD) may be wrong. Your due date is 40 weeks from the first day of your last menstrual period (LMP).

Babies born late pre-term are generally healthy but may have temporary problems such as jaundice, trouble feeding, problems with breathing, or difficulty maintaining body temperature. They may also be more likely than full term babies to have developmental or school problems later on.

Even though inductions do come with risks, going beyond 42 weeks of pregnancy can be risky, too. Many babies are born "post-term" without any complications, but concerns include:

Old wives' tales abound about ways to induce labor, such as the use of castor oil. It is not safe to try to artificially start labor yourself by taking castor oil, which can lead to nausea, diarrhea, and dehydration. And herbs and herbal supplements meant to induce labor can be harmful. Breast stimulation can cause uterine contractions by causing the release of oxytocin. However, some studies have suggested that the baby might have abnormal heartbeats after breast stimulation. Some women feel that having sex in late pregnancy can induce labor, but there is no conclusion on this yet.

Talk to your doctor before doing anything to try to encourage your little one's arrival. Inducing labor is best left to medical professionals — you may cause more harm than good.

As frustrating as it can be waiting for your baby to finally decide to arrive, letting nature take its course is often best, unless your doctor tells you otherwise. Before you know it, you'll be too busy to remember your baby was ever late at all!
