Reasons for caesarean birth
In some cases there is clear evidence that a caesarean section is needed to save life or to safeguard the health of mother or baby.
However, in other cases the best option isn’t clear. Doctors can read the same evidence in different ways and hold differing opinions on the need for a c-section. There are occasions when the choice is left to the parents. This article covers:
A caesarean may be recommended at any time during pregnancy or labour.
Sometimes a caesarean is definitely needed. You need a caesarean if you have:
- Placenta praevia: when your placenta lies across your cervix, the opening into the vagina.
- Placental abruption: when the placenta comes away from the wall of the uterus.
- Pre-eclampsia, which can develop into a serious medical condition of pregnancy.
- Umbilical cord prelapse: NICE guidelines state a caesarean section is needed in these cases ‘unless birth is imminent’.
You will also need one if your baby:
- Is lying in the oblique or transverse position.
- Has a particular medical condition that makes it necessary for her to be born by caesarean section.
In other cases:
- your baby is breech (lying bottom down),
- the progress of labour is considered to be too slow (failure to progress),
- the baby is believed to be in difficulty (foetal distress),
- you have a history of previous caesarean deliveries,
- you are carrying more than one baby,
and the decision is less straightforward.
As with all interventions in labour and pregnancy, you have to give your consent before you can have a c-section. However, if you are uncertain about the need for a caesarean it can be very difficult to disagree with your medical professionals, particularly if you are in labour.
Not all ‘emergency’ caesareans are urgent. The urgency of a caesarean (elective or emergency) has been graded into four categories:
- There is an immediate threat to the life of the mother or baby.
- Mother or baby are in difficulty, but it’s not immediately life-threatening.
- Mother should be delivered shortly, but neither mother nor baby are in difficulty.
- Delivery is timed to suit the mother and the staff.
Unless the circumstances of your caesarean fall into one of the first two categories, there should be time for you to seek more information to help you understand your situation and come to your own decisions.
It may be helpful to have a strategy for making decisions when medical help is offered. A strategy which many women have found helpful is the ‘BRAIN’ analysis:
Benefits: What are the benefits of the intervention?
Risks: What are the risks both to the baby and to yourself?
Alternatives? What other options are there?
Instincts? What do your instincts tell you?
Nothing: What if you don’t do anything?
Asking yourself, your midwife, and/or your doctor these questions, and thinking through the answers, will help you make decisions that are right for you.
