2 of the doulas in the group I belong to have attended births where it's been administered and they both agreed that they were the scariest births they have EVER attended in their careers. They literally thought the women were going to die they were in so much pain.

I have no idea why they would use it over another drug that has been approved and proven to be safer. I just know I wanted to post this after seeing it because, if for some reason, one of us "needs" something to help us along, and don't know about this beforehand... well, I would feel very guilty not having passed it along. It's really sad.
