I too am a midwifery student and am on the ICAN yahoo group. First, I highly suggest joining this group or at least going to the ICAN website. I am not allowed to post links yet) to get more information, specifically the white pages. Those ladies KNOW their stuff, they live and breathe cesarean and VBAC research.
About the OB tearing your uterus, this is actually a pretty common method that is done in cesareans.
Warning a slightly graphic description follows:
The Dr. will start the incision and make it big enough to get his/her fingers in there and then tear the tissue, the logic in this is that it will heal better as tears heal better than cuts as the skin will usually fall naturally back where it 'naturaly' tore especially since the uterus goes from a watermelon size down to a grapefruit in a matter of hours and, as it was explained to me, is that (quote) "when the body is cut with a scalpel the body doesn't get the proper trauma messages to beging knitting together and healing, think of how irritating a paper cut on your finger is. With trauma the body heals more rapidly".
Also the difference in outcome of single or double layer sutures is not proven. This does not exclude the option of a VBAC from all that I have read. This mostly depends on your care provider and what they are personally comfortable with and believe, which isn't necessarily what the research says so please be sure you are correctly informed.
(read: The Thinking Woman's Guide to a Better Birth and Obstetric Myths Versus Research Realities both by Henci Goer).
I highly suggest getting your medical records, specifically your surgical report. Often they will charge you for your records. But they are YOUR records and by law you are entitled to them and they HAVE to give them to you even if they do charge you. The charge is, IMO, their way of trying to persuade you not to get your records (for fear of a law suit I imagine). Though if you have another care provider (like a midwife

)that is willing to order your records for you and then give them to you, or better yet, read them with you and explain everything, that is a great way to go as that is almost always free. Another thing you could perhaps try to get them for free is to go and say you are moving, when I moved and got my records for myself and 2 children the hospital records department said it would be a few days and didn't charge me a penny. Go straight to the records department and not through your OB.
Also there has been a lot of discussion on the ICAN group lately about fertility issues post cesarean and I am sure they would have lots of information for you about this as well.
Again, please, go to the ICAN website and/or join the yahoo group and even find an ICAN chapter near you if you haven't already.
Love and light to you on your journey!
