Yes, Placenta Previa is one where a cs is needed. I AGREE, I want to make that clear. It's funny that didn't come to mind to me, as I am a VBAC and placenta previa is more common. In that case, yes, I would say a scheduled cs should be done. Of course, you should not go into labor as well, as it can be dangerous, and hemorrhage is a high risk and very dangerous for the two of you.
Yes with a transverse baby, of course a cs is needed too. I highly doubt the baby could be born vaginally without turning head down or breech. I think that one should go into labor on their own in this case, as the studies show it is better for mom and baby to labor some and OR wait for onset of labor. But, yes, a cs should be done, as a vaginal birth would be next to impossible.
Woman's rights in not "allowing" elective cs can easily turn into a discussion on abortion. As I am not wanting to go down that road, as that is not what this thread is about.
Personally, woman who want a cs because they "don't want to labor" (for reasons other than sexual abuse, etc), or because "it's convenient" or "it's what my dr. said" should not be allowed. You risk the baby's health, your health, and you up the cost of your maternity care, which in the long run can effect us all. Now, OBs who say, "your baby is too big", "your placenta is ageing" (when it is not proven) "your pelvis is too small/misshapen" (when it is not in a case of ricketts, dwarfism, injury etc) "I'm going on vacation", "It's near the end of the year", "we don't allow VBAC", I think are all wrong for a DR to enforce, let alone even tell a mom. I think this is wrong. I think to change it, we need to educate moms better what the consequences of their actions are, good or bad. I have never felt a mom has not taken into consideration the health of her or her baby. No mom would choose a more risky procedure if it unnecessarily put her or her baby at risk.
Just as I don't think an OB should use Cytotec for induction (other than abortion) I don't think they should use a cesarean for means of non medical uses. It's sad, Pitocin is not even FDA approved for induction without medical means, but it happens ALL the time. Yes, sometimes it should be used, just like a cs, when the risks of continuing the pregnancy out weigh the risks of the procedure. But, when you take away the risks of continuing the pregnancy, and there are none (non medical ones) then you only have the risks of the procedure and it is then too risky. Sadly mom's aren't all told this, and blindly choose inductions for non medical reasons.
