If you have had a caesarean section, you might be thinking if vaginal birth is an option for you or not. Many women who have had one previous caesarean section can safely have a vaginal birth (VBAC) in subsequent pregnancy or you can choose to have a caesarean section. There are some factors that can help you and your doctor decide if VBAC is right for you. The most important factor to consider is your and your baby's safety.

What Is The Success Rate Of VBAC?

Dr Dhivya Chandrasekar, Consultant Obstetrician & Gynaecologist, Sarjapur, Bangalore says “Studies have shown that success rate for planned VBAC is about 70-75% following one caesarean section. Only a minority of mothers who have had a caesarean section in the past will not be suitable to have a VBAC. Your obstetrician will advise you if it’s safe for you to attempt vaginal delivery based on your current pregnancy and previous medical history.”

Your chances of having a successful VBAC are high if

1. You have had previous vaginal deliveries either before or after your caesarean

2. Previous caesarean section was done due to baby reason

3. Your labour begins on its own just before or on the day of your due date

4. Your BMI is less than 30

5. During pregnancy both you and your baby are in good health

6. The time period from your previous caesarean section is eighteen months or more.

The following are some of the most common reasons for choosing a trial of labour after a caesarean section:

1. Influence on future pregnancies: If you intend to have more children, VBAC may help you to avoid the risks associated with multiple caesarean deliveries, problems with placenta in future pregnancies.

2. Lowers the possibility of surgical complications:  VBAC is associated with lower rates of excessive bleeding, infection, and blood clotting in one or more deep veins of the body. VBAC may also reduce the likelihood of uterine removal surgery and injury to abdominal organs such as the bladder or bowel.

3. Reduced recovery time: VBAC will result in a shorter hospital stay than a repeat Caesarean section. By avoiding surgery, you will be able to resume your normal activities sooner.

4. Your baby will have less chance of initial breathing problems

5. You are more likely to be able to have skin to skin contact with your baby immediately after birth and be able to breastfeed successfully

What Are The Risks Of VBAC?

1. You may need an emergency caesarean section. There is 25% chance of this happening

2. There is 1 in 200 chance that scar on your womb may weaken and open in labour. This may put you and your baby at risk

However, we will be able to identify the problem early by closely monitoring you while you are in labour and delivering you early if any problem arises.

You are not a candidate for VBAC if you have any condition that would make vaginal delivery impossible, or if you have had:

  • A previous “classical” caesarean section i.e., where the incision involved the upper part of the uterus
  • A uterine rupture during previous labour
  • Pregnancy complications that require a planned caesarean section

Dr Dhivya Chandrasekar also says, “It’s important that you should deliver at a hospital where there are senior health professionals available to look after you and your baby. Your baby’s heartbeat will be monitored throughout labour to identify any signs of fetal distress or any early signs of a problem occurring with the caesarean section scar. Every method of pain relief in labour will be available to you including epidural analgesia.”
