All about VBAC

I'm slow getting the notes up this month.  SO sorry!  We had our biggest group ever at the meeting this month and four VBAC moms shared their stories.  Thank you so much to everyone who came, and a very special thanks to those willing to give encouragement to future VBAC moms!


For hospital c-section rates and VBAC stats, check out The Unnecesarean.
In 2008 Texas had a VBAC State rate of 5.96 DFW is slightly lower at 5.32.

John Peter Smith Hospital in Fort Worth had the best VBAC rate at 18%.
Hospitals on the west side of DFW seem to have better VBAC rates ranging from 1.92 at Denton Regional Medical Center to 18 at John Peter Smith in Fort Worth.
Dr. Cummings at Texas Health Presbyterian Hospital in Denton (17.83% hospital VBAC rate) is noted for his support of VBAC moms.
Where the east side of DFW ranged from negligible at Dallas Regional Medical Center in Mesquite, to 12.4 at Methodist Dallas Medical Center.
*UPDATED* I received a comment from one of our moms regarding Dallas Regional Medical Center in Mesquite informing me that they have closed their L&D department.  While, according to the numbers reported to the CDC, 15 cesareans and <5 VBACs did occur at the hospital, they no longer accept planned deliveries there, which accounts for the negligible number of VBACs there.  The next lowest in the list on the east side of DFW is Texas Health Persbyterian Rockwall with 0%.
Dr. Downey at Methodist Richardson Med Ctr (19.1% hospital VBAC rate) or Plano Medical Center (6.68% hospital VBAC rate) is also noted for his support of VBAC moms.


The results of a 10 year study of uterine rupture.
Out of 114,933 deliveries, there were 39 total ruptures (.o34%), with 36 of them having a previous cesarean (.031%). Complete ruptures counted for 18 of those (.016% chance of complete uterine rupture). No mother deaths.
2 infant deaths (2 0f 114,933 deliveries is a 0.0017%). One of the deaths the mother had a previous cesarean, one had no previous cesarean.
According to the American College of Obstetricians and Gynecologists (ACOG), if you had a previous cesarean with a low transverse incision, the risk of uterine rupture in a vaginal delivery is .2 to 1.5%, which is approximately 1 in 500. - These numbers include labours that have been induced or augmented, which will increase risk.
RCS risks:
Usual risks of a surgical procedure (excessive blood loss, reaction to anesthesia
Hospital stay of approximately 4 days
Development of an infection in the uterus, bladder, or skin incision
Injury to the bladder, bowel, or adjacent organs (including the uterus which could result in the need for a partial or complete hysterectomy)
Development of blood clots in the legs or pelvis after the operation
On-going pain & discomfort around incision
Small chance that the baby will have respiratory problems – could be due to miscalculation of due date, also due to the fact that during a vaginal delivery, baby's lungs are compressed, helping to expel amniotic fluid from their lungs.)
Increased rick of asthma
Chance of baby being cut when the incision is made
Increased risks with each subsequent surgery - After you have two C-section scars, each added scar in the uterus raises the risk of placenta problems in a later pregnancy. These problems include placenta previa and placenta accreta, which raise the risk of problems for the baby and your risk of needing a hysterectomy to stop bleeding.
Baby doesn't get the advantages of mom's good bacteria coming down through the birth canal.
Increased chance of PPD
Challenges breastfeeding


VBAC risks
Less than 1% chance of uterine rupture. If uterine rupture occurs you have risks of blood loss, hysterectomy, damage to bladder, infection, & blood clots
Best research suggests that about 1.9 more babies die due to problems with the scar in every 10,000 VBAC labors, compared with planned c-section deliveries. Thus, about 5,200 women would need to experience risks of surgical birth to prevent the death of 1 baby from scar problems during VBAC.
Hospital stay of approximately 2 days (or none at all with a birth centre or home birth)
Risk of infection doubles if vaginal delivery is attempted but results in cesarean
Possibility of tearing or episiotomy
Temporary pain and discomfort around vagina
Urinary or bowel incontinence (about 3 in 100 still have a problem 1 year after birth)
