How Long Does an Induction Take for Second Baby
Are Fears of Inducing Labor Overblown?
Past studies have linked the procedure to an increased hazard of C-sections, merely new inquiry is commencement to flip that idea on its head.
This story was originally published on May 5, 2019 in NYT Parenting.
Ten days past her first kid's due date, Linda Finkbeiner faced a reckoning: Her son, she surmised, was never coming out.
The then 35-year-old special instruction instructor had tried the usual tricks: taking long walks, eating spicy foods. And aside from a thyroid condition that increased her hazard of miscarriage, her pregnancy had been trouble-gratis.
Just now, at 41 weeks and 3 days pregnant, and in bed in the infirmary, Finkbeiner was "massively uncomfortable." She wanted to be induced. "My midwife did warn me that induced labor is a lot more intense," said Finkbeiner. But she decided to go ahead with the procedure anyway and was confined to bed and put on continuous fetal monitoring to check her baby's middle charge per unit.
Soon after, Finkbeiner was hooked to an I.V. and given Pitocin, a synthetic version of the hormone oxytocin, which triggers labor contractions. Inside minutes, she felt a surge of pressure grip her pelvis. The contractions came and then fast and so hard that eventually she needed an epidural for the pain.
About 12 hours subsequently, Finkbeiner'south infant — all 7 pounds, 7 ounces of him — slid right out. Though the birth wasn't without complications. Every bit Finkbeiner's baby made his way through her birth culvert, his shoulder got stuck and wouldn't budge. Given the pick of a C-section or a vacuum extraction (which involves attaching a cup to the baby'due south head and gently using suction to pull the babe out) — Finkbeiner chose the latter.
That was ii years ago. When interviewed for this piece, at 36 weeks pregnant, Finkbeiner was debating whether to undergo another induction, in part because, unlike her last pregnancy, this ane had left her as ill equally a flu-ridden toddler, and the thought of having another grueling commitment experience sounded atrocious. "Just the suddenness of labor last time was so surprising," she said. "I'd like to experience what childbirth should feel like without being induced."
Few subjects provoke as much doubtfulness among expecting parents as the practice of induced labor. Until 2018, the American College of Obstetricians and Gynecologists advised doctors that, unless mother and fetus were in distress, they shouldn't induce labor until a pregnancy reached 41 weeks (39 weeks is considered full-term). At that point, they said, the risks of wellness complications for mom (similar high claret pressure) and for babe (like brain injury or breathing issues) could rise.
But, the thinking went, inducing earlier 41 weeks could increase the likelihood of a C-section. "Ten years ago, the entirety of my preparation we were taught that consecration increases the chances of cesarean," said Dr. William Grobman, M.D., a professor of obstetrics at Northwestern University.
As it turns out, that deeply-held idea was non based on sound science. And a few new studies have found that, in fact, inducing good for you women at 39 weeks isn't necessarily associated with an increased adventure of C-sections, and could be associated with some advantages, too.
Practice inductions cause C-sections?
Some of the earliest research suggesting that inductions increment the risk of cesareans was published in the 1970s and into the early 2000s. In one study, published in 1999 in the American Periodical of Obstetrics and Gynecology, for instance, researchers analyzed records of 7,000 women who were induced at a Kansas City hospital between 1990 and 1997. They plant that the offset-time mothers who were voluntarily induced had double the take a chance of C-section than the group that went into labor spontaneously. Another study, published in Obstetrics & Gynecology in 2000, institute similar results: Among the 1,135 women analyzed, the first-time mothers who were induced between 38 and 41 weeks were twice equally probable to have a C-section as the women who weren't.
But those and other studies were flawed, said Dr. Alison G. Cahill, M.D., an ob-gyn and subspecialist in maternal-fetal medicine at Washington University in St. Louis, Mo., because they were either observational — non randomized controlled trials — or poorly designed. "They used the incorrect comparison group, comparing those undergoing consecration to those in spontaneous labor," said Dr. Cahill. "No one can control when spontaneous labor occurs."
2 recent studies have revealed something entirely unlike: that inducing healthy women at term was not, in fact, associated with more C-sections, and may even offer some benefits.
One study of more than than 600 healthy women published in the New England Journal of Medicine in 2016, for instance, revealed that inducing labor in women over age 35 at 39 weeks did not enhance their chances of a cesarean. In 2018, Dr. Grobman and colleagues from several universities took that finding a step further with a randomized controlled trial — the gold standard of medical research — of more than half-dozen,000 good for you get-go-time mothers, half of whom were induced at 39 weeks, and one-half who went through labor on their own. The results, published in the New England Journal of Medicine, revealed that the women who were induced had 3 percent fewer C-sections than those who weren't.
"I retrieve it clearly shows that labor inductions do not cause cesareans," said Dr. Cahill, who was not involved with the study. "It's 1 of those times in medicine where we tin appreciate the value of a well-done trial to answer an of import clinical question."
Additionally, when Dr. Grobman and his colleagues compared the wellness of moms and babies in the induction and non-consecration groups, the researchers were surprised to find that the women who were induced were less probable to develop loftier blood pressure and pre-eclampsia after their procedures than those who weren't induced. In another twist, the moms who were induced as well reported less pain during labor and felt more than in control of their nascency experiences. And their newborns needed less help breathing than those who went into labor without an induction.

Should y'all be induced?
Dr. Grobman's 2018 New England Journal of Medicine written report was and so pivotal that ACOG inverse its guidelines in 2018 to say that doctors tin can offer induction at 39 weeks to first-fourth dimension mothers if both mom and fetus are healthy, and if she's not having twins.
Still, this study needs to be interpreted with caution, said Susan Rock, D.Due north.Sc., president of the American College of Nurse-Midwives. Because information technology focused on healthy, start-time mothers, it doesn't apply to all pregnant women, such as moms having their second or tertiary child, or those with health problems.
"Women do need to know all the information so they tin can brand their ain determination," said Stone. "But making sure you lot're non extrapolating this grouping of women to all women is really important." And as with all questions in medical science, more studies demand to be done.
And fifty-fifty if you are salubrious, there can exist downsides to induction, including that information technology doesn't always work, or that information technology tin cause unpleasant side effects, such as more intense and frequent contractions, nausea and airsickness, sinus issues and even memory issues. "If y'all're going to be induced, it involves Pitocin, you're going to be in bed, on continuous fetal monitoring, and then you're talking about a very different experience," said Stone.
Notwithstanding, these risks may not outweigh the benefits for some.
Later talking with her ob-gyn, Christine Escobar, an assistant professor of biology at Northwestern University, enrolled in Dr. Grobman'south study in 2017, when she was 6 months meaning. "Many hospitals were part of the study, so the results were promising," Escobar said. She and her husband as well relished the idea of boosting medical enquiry.
Escobar was 38 weeks along when she learned she was in the induced group. But she wasn't disappointed. She'd made peace with the idea that she might accept a nascency with interventions.
On May nine, her assigned date for her induction, Escobar arrived at the hospital at ix p.1000. "It feels a little like you're checking in to a hotel," she said. "You lot've got your suitcase. It's heady. You don't know what to look."
Twenty hours after she started on Pitocin, Escobar's doc nicked her amniotic sac to break her water and she delivered a daughter. "For me, it was a good choice," she said of her induction. "I don't know how it would have turned out if I'd been in the 'await-and-see' group. But it's an option that should be on the table and discussed with your doctor if information technology makes sense for you."
While more than studies are needed, Dr. Grobman said that his recent N.Eastward.J.1000. study is at least a start in helping moms who are eligible for induction to be more informed about the procedure, and ameliorate able to choose the birth experience they want. And while Stone praised the study for its rigor, she said that information technology's still important to understand what the medical intervention means.
Equally for Finkbeiner, she did end up getting induced again when, five days past her due date, a test revealed her baby'south center rate had jumped. Only this time, her labor experience was dramatically better. Only an hour afterward she went on Pitocin, Finkbeiner delivered an 8-pound, 10-ounce babe girl. And unlike her son's birth, her girl's was calm because just her midwife and a nurse had to be present in the delivery room. "Final time with the vacuum extraction, the md came in with his whole entourage, the pediatrician had to come in with all his nurses, so it was packed," she said.
After 2 starkly different experiences, Finkbeiner has a far more than nuanced view of the medical procedure than she did earlier. "If nosotros were going to have more children, I don't think I'd have a trouble being induced," she said. "I was grateful for the induction."
