We’ve all heard about women who were told they needed to consider an artificial induction of labor or even Cesarean surgery, because their babies “looked big” toward the end of pregnancy. Many of these women were unpleasantly surprised when their babies were born at completely average weights, after they’d undergone a drastic intervention in a healthy pregnancy.
The latest article from our brilliant Rebecca Dekker on her site EvidenceBasedBirth.com is “What is the evidence for induction or C-section for a big baby?” She confirms some sad news: 1 in 3 women in the U.S. are being told that their babies are too big, even though weight can’t be reliably predicted. Women are NOT being told that procedures such as artificial induction and Cesarean surgery for big babies have not been shown to improve outcomes, and, in fact, may be harmful. Induction for big baby likely increases the C-section rate.
Her article addresses the four “big” assumptions on which this approach is based:
- Big babies are at higher risk for problems.
- We can accurately tell if a baby will be big.
- Induction keeps the baby from getting any bigger, which lowers the risk of C-section.
- Elective C-sections for big baby are beneficial and don’t have any major risks.
In maternity care, treating assumption like fact can have devastating consequences. In this case, we see that the “suspicion” of a big baby is more harmful than an actual big baby!
When it comes to big babies, there is a clear disconnect here between what research says is best and what is commonly practiced all over the country. Please read Rebecca’s article and share far and wide.
Why Is It Important?
Suspected big baby (or macrosomia) is not a medical indication for induction or Cesarean, yet it is one of the most common reasons given for these procedures. In 2014, the American College of Obstetricians and Gynecologists issued guidelines to care providers recommending that they limit interventions for suspected baby to “avoid potential birth trauma.”
However, we know that it can take many years for guidelines like these and current research to be implemented into routine care.
What You Need to Know
Research shows that common interventions used for suspected big babies, such as induction and cesarean surgery, are actually more harmful and carry more risks than big babies themselves.
★ Non-diabetic, low-risk women are NOT at higher risk of complications due to baby’s size. In some cases, such as with mothers who have pelvic deformities or uncontrolled gestational diabetes, a large baby can be a medical indication for intervention.
★ MYTH: It is possible to predict which babies will be big.
FACT: Ultrasound estimates of babies size are unreliable, especially at the end of pregnancy. Predictions of a big baby are right 50% of the time and wrong 50% of the time.
★ MYTH: Big babies are at higher risk for complications.
FACT: In low-risk women, having a big baby does not put them or the baby at greater risk for complications.
★ MYTH: When there is a suspected big baby, intervening in labor and birth can decrease risk.
FACT: Statistically speaking, intervening due to a suspected big baby has been found to be more risky than the big baby itself and can lead to more complications.
