P.M.
You can always try to avoid a repeat abdominal surgery and go with a Midwife for a VBAC. I'm a second time around Mom, and due to my clinical training and prior experience with child birth unnecessarily snowballing into a cesarean - I've chosen to use a Midwife for this pregnancy and DAMN AM I HAPPY!!!
In my clinicals at an OB hospital, I had to watch women - who completely put their trust in their OBs, be scheduled for a major abdominal surgery simply because the OB was busy, didn't feel like waiting, had to get home or didn't want another OB to be the one paid for delivery their patient's baby. I also watched 6 cesareans - each one made me cringe and pray to all who was listening that I would not have to go thru such an operation again.
Each time you go under the knife - your chances of death increase. Anesthesia issues, cauterizing the wrong blood vessels, not seeing all the vessels left open (hemorrhage), puncturing of the bladder, intestines, kidney (all causes sepsis in under 24 hours and death if not caught before then) or even puncturing the baby. Most Mothers are not aware of the major life or death situation they make when they choose a cesarean or go to hospitals/OBs with a high cesarean rate.
