I really doubt her stillbirth was truly the first to be resolved with the Kleihauer test. This test has been around for many years, and is frequently performed if Rh disease is suspected. Who actually said that she was the first? JFW | T@lk 22:22, 13 February 2006 (UTC)
Perhaps hers was the first stillbirth to be completely nailed down to Rh (i.e. Rh was 100% at fault for the stillbirth) via the Kleihauer-Betke test. Perhaps previous tests were only able to be sure with <100% probability that Rh was to blame. With Bree Lynn's size, it seems like something unusual was up. And a 45 week pregnancy just isn't healthy, any day of the week. I'm looking at a paper on the study conducted on Bree Lynn's stillbirth, and those authors seem to maintain primality of the resolution of the stillbirth by K-B. So who knows? Additional research seems to be in order.
- A very large fetus is in most cases the cause of gestational diabetes, and can also be caused by a gestation period longer than 40 weeks. From my understanding, Rh incompatibility does not harm the first baby, but rather, the Rhogam shot is routinely given during the first pregnancy of an Rh negative mother to prevent harm to the fetus in subsequent pregnancies. Also, since Rh incompatibility causes the mother's blood to produce antibodies (during the first pregnancy) that attack the fetus (in subsequent pregnancies) if it has Rh positive blood, this would be more likely to cause growth restriction before death, not increased growth. bcatt 13:00, 4 March 2006 (UTC)

- That's interesting. I always heard that gestational diabetes *caused* heavy babies. I can certainly understand the correlation between high birth weight and overdue pregnancies - the more time a baby has to grow, the more she'll grow. I'm trying to research Breanna Lynn's birth more - I had the same question that you did about whether she was Lisa's first baby. None of the information I've seen indicates one way or another. Your last thought on Rh causing growth restriction is interesting, as well. I'm going to do some research into this and see if I can come up with some data on the birth weight of Rh babies. Have you listened to my attempt to record this article? Let me know what you think. Thanks for your input here, BobbyLee 03:01, 5 March 2006 (UTC)
- Yes, that's right...I may have worded it funny, but I was saying that gestational diabetes does tend to cause very large babies...sorry for the misunderstanding. I did try to listen to the audio version of the article before I went on wikiholiday, but it wasn't working for me (I think it had something to do with the audio format and incompatibility with my computer), but I'll try listening to it again and see how it goes. Also, I'm interested in knowing about anything you come up with regarding Rh positive babies born to Rh negative mothers (I am Rh neg and had the Rhogam injection during my pregnancy, but my daughter turned out to be Rh neg anyway). bcatt 04:31, 13 June 2006 (UTC)
