My midwife just gave me a copy of her conference statement from last years VBAC conference by the National Institutes of Health, and it has some pretty good statistics in it. They focused on comparing stats for VBAC v's RCS.
One of the most interesting ones for me was maternal mortality. 3.8 per 100,000 for women who undergo trial of labor after c-section (regardless of actual outcome) v's 13.4 per 100,000 for elective repeat c-section. At term the numbers change to 1.9 per 100,000 for TOL v's 9.6 per 100,000 for ERCS. Now that is a stat OBs will never tell you.
It also shows the dramatic increase of risk of needing a hysterectomy with each repeat c/s, again something that is rarely admitted by OBs. Overall risk of hysterectomy for TOL v's ERCS is 157 v's 280 per 100,000 respectively, increasing with the no of RCS to 900 for 2 RCS, 2,410 for 3 RCS, 3,490 for 4 RCS & 8,990 for 5+ RCS each per 100,000 live births.)
For the dreaded Uterine Rupture the stats are: 325 per 100,000 for TOL v's 26 per 100,000 for ERCS. Having labor induced increases the TOL no to 1, 500 per 100,000. Of these ruptures only 6% will result in perinatal death, making the overall risk of intrapartum fetal death of 20 per 100,000 women undergoing trial of labor This is then halved for those with term pregnancies to 3% & 10 per 100,000 respectively.
All of these stats are from "NIH Consensus and State-of-the-Science Statements Volume 27, Number 3 March 8-10, 2010" NIH are part of the U.S. Department of Health and Human Services. Their web address is http://consensus.nih.gov
Hope these stats can help to put the risks into some perspective.
