Having a baby when you have had a Caesarean before
You have had a previous Caesarean section. This leaflet aims to give you information on your birth options in this pregnancy.
What are the chances of having a vaginal birth?
Many women who have had a Caesarean section can safely have a vaginal birth in a subsequent labour. This is known as Vaginal Birth after Caesarean section (VBAC). As long as there are no reasons not to, you will be offered and encouraged to try for a vaginal delivery. The evidence suggests that this is advantageous for you and has no significant adverse effect on your baby. Studies have shown that of those women who chose vaginal birth after Caesarean section, between 60 – 83% would be successful.
What are the risks of attempting a vaginal birth?
A mother who has had a previous Caesarean has a small risk of the womb (uterus) rupturing. This happens because the scar on the uterus tears open during the strain of labour; the risk of this happening is around 1 in 300 (0.35%). If your labour is induced the risk of scar rupture is higher at up to 2 – 3% (depending on the method used). However, you are more likely to need a Caesarean section for reasons other than scar rupture, e.g. the baby becoming distressed during labour or not making good progress.It is because of this small risk of scar rupture that you are advised to have your baby in hospital, with monitoring of your baby’s heart and facilities to perform an immediate repeat Caesarean if needed. If scar rupture occurs in the hospital setting the chances for you and your baby are excellent.The progress of your labour will be closely watched and if you are not making good progress a repeat Caesarean will be advised. You will be able to have an epidural during labour, if you wish.If you give birth vaginally you will have an even better chance of future vaginal births, avoiding the risks of a repeat Caesarean.
