New Study On Scheduled Cesareans

There is a new comprehensive study about the safety of cesareans before 39 weeks gestation.? From the article, Early Repeat C-sections Increase Risks, Study Finds, published in the Washington Post, there is this quote about the study:

The study of more than 24,000 full-term infants found that those delivered at 37 weeks to mothers who had elective repeat C-sections were about twice as likely as newborns delivered at the recommended 39 weeks to experience breathing problems, bloodstream infections and other complications. Babies born at 38 weeks were 50 percent more likely to have problems; the risk was about 20 percent higher just a few days early.

The article states that the rate of cesareans is now over 30%, and that there is a great deal of debate as to why this is.? However, they then go on to say:

Although a pregnancy is considered full term after 37 weeks, the American College of Obstetricians and Gynecologists recommends that elective repeat C-sections occur no earlier than 39 weeks to make sure the baby has fully developed. But some women opt to deliver a little earlier for a variety of reasons, including being eager to see their baby, being tired of pregnancy or for convenience.

The article here suggests, with no data or studies to back it up, that the women themselves are convincing their OB’s to disregard their instructions from ACOG, go against evidence based care, and put the babies at risk in order to give in to the mothers whims.? I find it very curious that women hold so much power in this regard, when most other choices they make in childbirth in a typical hospital would be disregarded.? If doctors are so concerned for mothers choices, even when it means breaking their own rules and putting babies in harms way, then why aren’t the choices that women make for their labors and births that do not infringe on any rules or cause harm to their babies respected?? I doubt very much that doctors are truly allowing women to make an informed choice on this.? Perhaps women who are getting a repeat elective cesarean are showing an interest in an earlier delivery, but, are they then given the risks, benefits, or alternatives to delivering early?? Did they make a truly informed choice?? Or are they making a decision based on the belief that their baby is “full term” and is ready to be born?? In the absence of any cited study on the subject, it is my feeling that the article is making quite the presumption.

Here is all the study really had to say about the matter:

Of 24,077 women who gave birth through a repeat C-section between 1999 and 2002, 13,258 were clearly elective — meaning the researchers could find no evidence that the baby or mother was in distress or any other medical reason the woman could not attempt to deliver through labor. Of those, nearly 36 percent of the deliveries occurred before 39 weeks.

It is unclear from the study why there were so many “elective” cesareans performed.? It is not clear to me whether the researchers considered a repeat cesarean to be elective or not.? If the researchers didn’t consider a previous cesarean as a medical reason as to why the mother should have another one, then that would explain the large number of scheduled “elective” cesareans.? It doesn’t seem that any data was provided as to whether the mothers or the doctors were selecting the time in which these cesareans would be scheduled.

The articles goes on to talk about the findings in the study about the true risks of a scheduled cesarean before 39 weeks:

More than 15 percent of the babies delivered at 37 weeks suffered a complication, such as problems breathing, low blood sugar, infections or conditions that required intensive care, compared with about 8 percent of those delivered at 39 weeks. About 11 percent of those delivered at 38 weeks experienced complications. Babies born at 37 weeks were four times as likely as those delivered at 39 weeks to have breathing problems.

It seems very clear cut, but then another angle is presented:

While other experts agreed that the study provides important information to help women and their doctors make decisions about timing C-sections, some said the risks of complications are relatively low and need to be weighed against the small but not insignificant chance that waiting a week or two would result in more stillbirths.

The article does end with a voice of reason though:

But Spong said the magnitude of the risk of stillbirth from waiting is unclear, and the new study shows the risks of complications from early delivery is significant.

“It’s hard to advocate doing a Caesarean at 37 weeks to try to prevent a stillbirth when we don’t really know the true risk,” she said.

Overall, I feel this is a very good study that has been done.? Many babies and new parents will be saved the possible traumatic experience of the NICU.? Many doctors, who already had some research and guidance from ACOG to tell them not to schedule repeat cesareans before 39 weeks, will now have this additional comprehensive study that clearly shows the impact of doing so.? This also may bring to women’s and doctor’s consciousness that cesareans themselves are not perfectly safe for all involved no mater what.? They need to be carefully planned and managed and only performed in cases of true emergency, or they could possibly do more harm then good.
