VBAC Evidence & Success:
A Mindful Guide to Vaginal Birth After Caesarean

Having a VBAC in Ontario: Evidence & Statistics

Navigating Your VBAC Journey with Confidence

For many families in Collingwood, Barrie, and Orangeville, the decision to pursue a Vaginal Birth After Caesarean (VBAC) is a deeply personal one. As a Childbirth Educator, my goal is to provide you with the objective data you need to move from a place of uncertainty to a place of empowered, informed consent.

Choosing a VBAC is not just about the "how" of birth; it is about reclaiming your rhythm and trusting the physiological process, supported by modern evidence.

The Evidence: VBAC Success Rates & Benefits

Research consistently shows that for the majority of people with one previous low-transverse Caesarean section, a Trial of Labour After Caesarean (TOLAC) is a safe and appropriate option.

VBAC Statistics at a Glance

  • Success Rate: Approximately 75% of people who attempt a VBAC will successfully give birth vaginally.

  • Repeat Success: If you have had a prior vaginal birth (either before or after your C-section), your success rate climbs to nearly 90%.

  • The "Why" Matters: Success rates vary slightly based on the reason for your initial C-section (e.g., a breech baby has a higher VBAC success rate than a "failure to progress" diagnosis).

Evidence-Based Benefits of a Successful VBAC

  • Faster Physical Recovery: Avoidance of major abdominal surgery allows for a quicker return to daily movement and yoga-based stretching.

  • Lower Infection Risk: Reduced risk of surgical site infections and postpartum haemorrhage.

  • Respiratory Benefits for Baby: The "squeeze" of a vaginal birth helps clear fluid from the baby’s lungs.

  • Easier Initial Breastfeeding: Many families find that the immediate skin-to-skin contact following a VBAC supports an easier initial latch and lactation journey.

Understanding TOLAC & VBAC Risks, Benefits and How-To

Understanding the Risks: Uterine Rupture

The primary concern during a VBAC is the risk of uterine rupture (the previous scar opening). While this is a serious event, it is statistically rare.

  • The Risk Level: The risk of uterine rupture during a TOLAC is approximately 0.5% to 0.9% (or about 1 in 200).

  • Context: For most low-risk families, the risk of complications from a repeat major surgery is statistically higher than the risk of a rupture.

Signs & Symptoms of Uterine Rupture

During your labour at hospitals like CGMH, RVH, or Headwaters, your team will monitor for these signs:

  • Abnormal Fetal Heart Rate: This is the most common sign (often a sudden drop in heart rate).

  • Severe, Localized Pain: Pain that persists between contractions, specifically over the previous scar site.

  • Loss of Fetal Station: The baby moving "up" rather than descending.

  • Vaginal Bleeding: Unexpected or heavy bright red blood.

  • Changes in Contraction Pattern: Surges suddenly becoming weaker or stopping entirely.

Factors That Influence Your VBAC Success

Factors That May Increase Success

Prior Vaginal Birth: The strongest predictor of a successful VBAC.

Spontaneous Labour: Entering labour on your own significantly boosts success rates.

Optimal Foetal Position: Using yoga and "Spinning Babies" techniques to ensure baby is well-positioned.

Continuous Doula Support: Having a dedicated "anchor" to manage stress and movement.

Factors That May Decrease Success

Induced Labour: Using certain prostaglandins can slightly increase rupture risk.

High Maternal BMI: Can be a complicating factor in some clinical settings.

Short Inter-pregnancy Interval: Less than 18 months between births.

Advanced Maternal Age: Though many over 35 have very successful VBACs.

How We Optimize Your VBAC at Doula By The Bay

A successful VBAC is often as much about the "mind" as it is about the "body." We work together to create a Safety Nest for your birth:

  1. Mindfulness & Pain Management: We use meditation and music to keep your adrenaline low. High stress can stall labour, and for a VBAC, "keeping things moving" is key to avoiding an unnecessary repeat C-section.

  2. Active Labour Positioning: Drawing on my yoga background and training in fetal positioning, we use gravity and pelvic mobility to help the baby descend, reducing the pressure on your scar while maximizing the efficiency of your surges.

  3. Specialized Massage: I provide sacral pressure and relaxation massage to keep you comfortable, helping you stay at home as long as safely possible before transitioning to the hospital.

  4. Advocacy & Education: We review the 9 Qualities of Mindfulness to help you stay present and grounded during clinical conversations about monitoring and timelines.
