I just got word that a sister from southern California died today after giving birth yesterday. This was secondhand information, but this is the info I've heard so far:
After giving birth, she felt light-headed in her bed in the recovery room. The doctors found that she was bleeding internally and took her into surgery. She came out fine. Sometime this morning she started bleeding again so the doctors took her back into the OR. This time she didn't make it.
I'm not sure how much of an issue blood transfusions came into play here, but since she was a JW in good standing, I assume both her and her husband told the doctors "no blood." This info was told to me by a JW who knows my stance on blood. But they didn't say anything on whether or not blood transfusions were an issue. I'm not sure if they were told if it was.
Keep an eye out on the newspapers for this story - I'm sure it will come out pretty soon.
(just a guess, but this probably happened somewhere around Temecula or a little north of there)
