UNC study: C-section timing is critical

— Scheduling a cesarean section takes a lot of uncertainty out of the birth of a baby. That is often why couples choose them. However, according to a new study, exactly when a c-section is done is more critical than once thought.

Before the study, doctors thought the window of opportunity to perform a cesarean section was a couple of weeks before or after the due date.

Now, the study – done in part at UNC Hospitals – narrows the timing down to one week before.

Two weeks earlier and the risk of breathing or feeding problems were twice as high. The risks are four times higher at the three weeks earlier mark. A week and two weeks after the due date also showed increased risk, the study found.

Shannon and Gaston Eubanks said they knew son Charlie was going to be a big baby and that he was in a breech position. They scheduled a c-section for his birth two years ago. Their next baby also had the same issues.

The girl's due date was Jan. 10, but in scheduling a c-section, the Eubanks wondered if it could be done before the New Year for tax purposes. Their doctor, UNC Hospitals obstetrician John Thorp, said, 'no.'

“I'm an accountant and it has driven me nuts that I did not get a tax deduction,” Shannon Eubanks said.

Thorp is co-author of the c-section study published in the New England Journal of Medicine. It found that among women who had one or more elective c-sections, exactly when the next one is scheduled can be critical.

“What we found was that there is a very narrow window between 39 weeks and a mom's due date, which is 40 weeks,” Thorp said.

“This is a different window from labor, where we know that anything between 37 and 41 weeks is optimal,” Thorp said.

Knowing the risks, the Eubanks decided to schedule the c-section four days before the due date, but still too late for a 2008 tax write-off.

“I knew that the benefits and healthy ramifications outweighed the tax benefit. So I'm OK with that,” Shannon Eubanks said.

The Eubanks had daughter Kathleen on Tuesday. Both mom and baby are doing well.

There is another notable difference among children born through c-section. Squeezing the baby through the birth canal helps get rid of excess fluid. The extra stress on the baby may have effects that help make that transition between depending on the placenta for food and oxygen and feeding and breathing on their own after delivery.

However, babies born through c-section do very well in that one week before the due date, Thorp said.

    I have had 2 C-Sections, my son was late and I never went into labor even when induced. My daughter was born EARLY via c-section because of complications, it's not the ideal way to have children but for me, it was necessary. I think if it's medically necessary then it should be done...otherwise, "Happy laboring!"

    More nuts than the thought that your child could have been born unhealthy or had huge complications if you had gotten your way??? Get over that and get your priorities straight lady!

    Bijoux - spot on! Further, didn't he get the same right off the next year and will be able claim the childdeduction one year long as a result? I'm sure he will change his view as the kids grow...

    I have always considered C-sections an emergency measure, as in case a woman did not fully dialate, not a matter of convenience. My ex-wife and I had our son by way of cesarian, but only because her water broke and she never went into hard labor or fully dialated.

    I was completely miffed when I saw this segment last night.
    There's so much more I want to say about this, but I'm biting my tongue with all my might.

    ADD- you hit the nail on the head!

    I believe that C-sections for convenience, like the use of genetic testing for determination of sex for reasons of curiosity, is a frivolous and unjustified use of a very advanced and very expensive technology.

    Resources of this type are better conserved for more dire needs.

    It's rather greedy to want to have your child too long before it's due date just because you want a tax write-off. I would think that the health of the baby would be more important. Speaking as a pregnant woman, I intend to have my child naturally, unless circumstances come where my doctor recommends a C-section. I'd much rather my daughter come when she's ready instead of putting her health at risk.

    I've had 2 C-sections and I can't imagine 'opting' for that. Childbirth is natural. C-sections are a nice way to keep yourself and your child out of harms way if something goes wrong.
