This has been bugging me and I didn't think to ask it at my last OB appt. I thought I'd ask here since you are all so knowledgeable.
With DS I had SROM but he was not yet engaged. The L&D nurses and my OB at the time told me because there was a chance the umbilical cord could get pinched under his head, which is obviously really bad, I would have to stay either sitting or lying in bed to prevent it. My new OB agreed that, that is the "standard recommendation" and he would suggest following it because, even though there is a very small chance of it happening, the effect would be emergency c-section.
The more I think about it the more it seems like the recommendation itself has absolutely no basis. Once SROM occurs there is no longer a liquid buffer allowing for room for the cord to just slide by the head. It seems to me whether the cord is above or below the head is pretty much a done deal at that point. I suppose if I was doing hand stands or something that might shake things up enough to give it room to slip on by but I don't see why walking would make any difference. Do any of you know the logic behind this recommendation?
