Hi Katy,

Wow. I don’t know where to start except by saying that you are actually pretty fortunate. You have the benefit of time to weigh the risks and benefits. If this had been a bedside decision while you were already in labor, you would probably have to do your due diligence AFTER your baby was already born.

One thing… are you sure about the GDM diagnosis? You were in the normal range at 30 weeks. The closer a woman gets to giving birth, the less accurate the results of GDM testing are. From what I understand, there isn’t consensus on what the cut-off should be for routine tests. What would the point be for re-testing after you had already had a negative test at 30 weeks? It sounds odd to me and maybe Henci will address the research on GDM issues when she replies.

Could you be further along than you think you are? Ultrasounds are not accurate predictors of fetal weight, so the 34 week estimate might be off. Have you considered that your due date might be earlier than you think it is?

Have you already read ACOG’s Practice Guidelines on fetal macrosomia? It reads, “In cases of term patients with suspected fetal macrosomia, current evidence does not support early induction of labor.” In 2005, a huge retrospective analysis was done in California on 267,228 vaginal births and found 1,686 cases of shoulder dystocia—a rate of 0.6%. The study showed that when the triad of Pitocin, induction, and birth weight greater than 4,500 g (9 lb., 15 oz.) was present, shoulder dystocia was 23 times more likely to occur. This suggests that induction of babies that are actually macrosomic might cause shoulder dystocia (Ouzounian, 2005).

Three weeks of AFT/NSTs is a lot. You do not have to submit to a final growth scan if you don’t want to. Sometimes it’s better not to know and better that your doctors don’t know. What would you do with the information at this point? What would they? Those are rhetorical questions, by the way.

I’m finding myself right now spending an inordinate amount of time trying to decide what to say succinctly (and failing at the succinct part). I blog about this a lot but I usually don’t jump in and chat with women directly, but I just answered a similar concern elsewhere last week which will tell you where I’m coming from.

You are not alone—this scenario is increasingly common. And yes, I think you are correct in saying that they are working really hard to scare the crap out of you. Just wait until they start telling you about procto-rectal episiotomies and the Zavanelli maneuver.

I was in your shoes four years ago to the day (with two exceptions: they scheduled me a c/s and the pointless GDM test, which they did a few days before I gave birth was “normal but on the high end”) and we had a really hard time fighting off a cesarean. I wasn’t planning on any interventions in labor if I could avoid them, nor was I opposed to surgery if there was an actual need for it. I also had the benefit of time, which I used to read medical journals and articles. It was a really stressful and fairly morbid way to spend the last week and a half of pregnancy when all I really wanted to do was nap and compulsively fold and organize baby socks.

I also had a Bizarro World experience when a friend convinced me to go spend a few hours with her home birth midwife. The only person in the last week and a half of my pregnancy that gave me any evidence-based information on shoulder dystocia, ultrasounds, macrosomia and birth in general was a home birth midwife. I looked up everything she told me and everything the doctors told me (which was not based on anything but their personal anecdotes) and it blew my mind. I’ve never really looked at the world the same, honestly.

I also knew intuitively that I had a big baby on deck based on my family’s history and knowing this reinforced my desire to stay mobile and active in labor. I’m really glad I did. If you want to read stories of big babies (4000 g+) born vaginally (in hospitals and at home), there are tons on my site. Unnecesarean—Birth Stories

My contact info is on the site if you want to e-mail me. I hope you will if you have any questions about my experience.
