VBAC (Vaginal Birth After Cesarean) is a safe option for 60 to 80 percent of women with one previous low-transverse cesarean, offering faster recovery, lower infection risk, and shorter hospital stays than a repeat cesarean. Safe outcomes depend on proper candidate selection, hospital readiness, and continuous monitoring during labour.
According to Dr. Reshma K Priya, an experienced Gynaecologist in Bhubaneswar,
“VBAC eligibility depends on the type of previous uterine scar, the reason for the earlier cesarean, and the current pregnancy. A careful scar assessment, full birth-history review, and a hospital with 24/7 emergency cesarean capability are non-negotiable.”
Who Can Try Vaginal Delivery After Cesarean?
Not every woman with a previous cesarean is a VBAC candidate. Eligibility depends on the type of previous scar, the reason for the earlier cesarean, current pregnancy details, and hospital infrastructure.
Factors that make a woman a strong VBAC candidate:
Previous low-transverse uterine incision:
The most common type and lowest risk for scar rupture
Only one previous cesarean:
Best safety profile for VBAC
No history of uterine rupture or classical incision:
These absolutely rule out VBAC
Singleton pregnancy with cephalic presentation:
Baby head-down
Adequate pelvic dimensions:
Confirmed clinically
Spontaneous onset of labour:
Or carefully managed induction
No major obstetric complications:
No placenta previa, severe preeclampsia, or active infection
Estimated fetal weight under 4 kg:
Reduces risk of obstructed labour
Hospital with 24/7 emergency cesarean and blood bank facilities
VBAC eligibility factor | Outcome |
One previous low-transverse cesarean | Eligible, success 60 to 80 percent |
Two previous cesareans | Eligible only in selected cases, lower success |
Previous classical or T-shaped incision | Not eligible |
Previous uterine rupture | Not eligible |
Previous cesarean for cephalopelvic disproportion | Reduced eligibility, lower success |
Previous cesarean for non-recurring cause (breech, fetal distress) | Strong candidate |
A complete pre-pregnancy or early-pregnancy assessment helps confirm whether VBAC is appropriate. See Pregnancy Care in Bhubaneswar for a detailed VBAC evaluation.

Warning Signs During Pregnancy and Labor That Require Immediate Attention
A VBAC attempt requires close monitoring because complications, although uncommon, can occur quickly. The most serious risk is uterine scar rupture, which happens in less than 1 percent of cases but needs immediate cesarean delivery if detected.
Warning signs during pregnancy that need urgent review:
Severe abdominal pain:
Constant pain over the previous scar
Vaginal bleeding:
Any unexplained bleeding in second or third trimester
Reduced fetal movements:
Fewer than 10 movements in 2 hours after 28 weeks
Leaking amniotic fluid:
Before 37 weeks
Blood pressure of 140/90 mmHg or higher:
Possible preeclampsia
Severe headache with vision changes
Warning signs during labour that signal scar rupture or other emergencies:
Sudden sharp pain over the previous scar:
Often described as tearing
Loss of contractions or sudden change in labour pattern
Vaginal bleeding during active labour
Sudden drop in baby's heart rate on CTG
Maternal tachycardia or low blood pressure
Recession of the baby's head (going back up the birth canal)
For high-risk cases, high-risk monitoring during labour ensures any complication is caught and managed immediately. Continuous electronic fetal monitoring throughout labour is standard for every VBAC attempt.
Planning for a Safe Delivery After Cesarean Section
Safe VBAC planning starts well before labour. It includes detailed counselling, hospital selection, and a clear backup plan for emergency cesarean if needed.
The planning process includes:
Step 1: Detailed history and scar assessment
Review of the previous cesarean type, indication, recovery, and any complications. Ultrasound assessment of the lower uterine segment thickness if needed.
Step 2: Counselling on risks and benefits
Benefits of VBAC | Risks of VBAC |
Faster recovery (3 to 5 days) | Scar rupture (less than 1 percent) |
Lower infection rate | Need for emergency cesarean (20 to 40 percent) |
Shorter hospital stay | Slightly higher blood transfusion risk |
Lower future complications | Possible failure of trial of labour |
Earlier mother-baby bonding | Continuous monitoring required |
Reduced surgical risks | Hospital-based delivery essential |
Step 3: Setting realistic expectations
A 60 to 80 percent success rate means a meaningful chance of needing a repeat cesarean. Mental and emotional preparation for both outcomes is part of safe planning.
Step 4: Birth setting and team
Delivery should be in a hospital with 24/7 emergency cesarean, blood bank, anaesthesia team, and neonatal ICU. Home birth or low-resource settings are not safe for VBAC.
Step 5: Labour management
Spontaneous labour onset is preferred. Induction is possible but uses careful protocols. Pain relief options including epidural are safe during VBAC. Continuous fetal monitoring is mandatory throughout active labour.
Step 6: Postpartum care
Close monitoring for first 24 hours to check for delayed bleeding, scar tenderness, or signs of late complications. Discharge typically within 2 to 3 days after uncomplicated VBAC.
At Rahat Hospital, Bhubaneswar, VBAC candidates are managed with gynaecologist-led monitoring, continuous CTG during labour, anaesthesia and operation theatre standby, and round-the-clock neonatal backup, providing the safest possible environment for vaginal delivery after a previous cesarean.

FAQs
Is vaginal delivery after cesarean safe?
Yes, VBAC is safe for carefully selected women, with a 60 to 80 percent success rate. The main risk, scar rupture, occurs in less than 1 percent of cases and is managed by immediate emergency cesarean in a properly equipped hospital.
How long should I wait between cesarean and the next pregnancy for VBAC?
At least 18 months between delivery and the next conception. A shorter gap increases the risk of scar rupture during VBAC.
Can I have a VBAC after two cesareans?
It is possible in selected cases but with reduced success and slightly higher risk. The decision is made after detailed individual assessment.
Will I need continuous monitoring during VBAC labour?
Yes. Continuous electronic fetal monitoring is mandatory throughout active labour to detect any signs of scar stress or fetal distress early.
Can VBAC labour be induced?
Induction is possible with careful protocols. Prostaglandins are usually avoided due to scar rupture risk. Oxytocin and balloon catheter induction are safer alternatives under close supervision.
