Caesarean versus vaginal birth

If you are researching your childbirth options, this section tries to provide a balanced high level list of the positive and negative aspects of both forms of delivery. The two methods are very different and carry some identical risks and some very different risks. It is your feelings associated with the positives and negatives that should inform your choice, not pressure from other people.

A study reported in the Obstetrics and Gynaecology journal reports that "The risks of CS [caesarean section] and labour are real but different, and if fully explained to the woman, she should be allowed to accept one set of risks over the other - after all she is the person who has to live with the consequences. An elective CS in a fit healthy woman is neither unsafe nor bad practice if she truly understands the risks involved and is adamant that she cannot accept the risks of labour or vaginal delivery." 45

We recommend that you search out real experiences too as this will provide you with more concrete examples of these factors. Our connect you to other people who have had or are thinking about caesareans. Talk to your family and friends but always bear in mind the following:

Positive aspects of caesareans

Negative aspects of caesareans with regional anaesthetic

Negative aspects of caesareans with general anaesthetics

An emergency caesarean with a general anaesthetic is different to regional anaesthesia (Spinal or Epidural) In addition to the risks already outlined you should bear in mind the following:

Vaginal births after a caesarean

If you have a caesarean on a previous delivery, it is quite possible to go on to have a successful vaginal birth on your next delivery should you want to. This is known as Vaginal Birth After Caesarean (VBAC). 33% of women do go on to successfully deliver vaginally 14 however a VBAC does carry, when coupled with induction, an increased risk of the uterus rupturing 59. The National Institute for Health and Clinical Excellence (NICE) 27 state that the risk is between 80 and 240 per 10,000 women depending on the type of drugs used to induce labour. A recent study found that in addition to an increased risk of uterine rupture a very small number of births experienced oxygen depravation and associated damage after a VBAC with no occurances of this with elective caesareans. In addition they found that "the rate of endometritis was higher in women undergoing a trial of labor than in women undergoing repeated elective cesarean delivery (2.9% vs. 1.% ), as was the rate of blood transfusion (1.7% vs. 1.0%). The frequency of hysterectomy and of maternal death did not differ significantly between groups (0.2% vs. 0.3%, and 0.02% vs. 0.04%, respectively)." 114

The risk of an infant death during the birth process (following an earlier caesarean) is small for women who have a planned vaginal birth (10 per 10,000), but this is even lower with a planned caesarean (1 per 10,000) 27. Vaginal Birth After Caesarean (VBAC) organisations are an excellent source of help and support in assessing this risk and improving your chances of a vaginal birth, should you want one.

Making a choice

Unless you are in a situation where medical indications make it critical for your baby to be delivered by caesarean, the decision should ultimately be yours. In reality it can be quite difficult to gain formal agreement for an elective caesarean, particularly if you are a risks associated with both forms of delivery, but this is particularly the case if you have had a previous caesarean. In such instances studies show that while the "absolute risks are low" there are marginally greater risks associated with Vaginal Birth After Caesarean (VBAC) than with an elective caesarean (pre-labour) 104.

By researching your options you can make the decision making process much easier. A study looking at the outcomes for the baby after a caesarean delivery concluded that "the choice for a woman is not between planned caesarean section and vaginal birth, but rather [caesarean and] an attempt at vaginal birth. In the latter category, the final mode of delivery can be spontaneous vaginal delivery, operative vaginal delivery or emergency caesarean section." Researchers stated that with vaginal deliveries the absolute risks of short-term problems such as infection, bleeding, surgical injury and thromboembolism was much lower than for a caesarean. 114 But went on to state that such short-term risks were "2-3% among women delivering vaginally, 3-4% among those delivered by planned caesarean section, and around 14% among women delivered by emergency caesarean section during labour." In other words while the risks associated with an elective caesarean are fractionally higher than with a vaginal birth, they are significantly lower than with an emergency caesarean. 104

It is important that you are happy with your choices. In the case of Tokophobia it is particularly important that you have looked at all the options and are happy with your choices. A study in 2000 clearly showed the importance of this: "women with primary tokophobia (a fear of Birth before they have had any children) strongly desired a caesarean birth. Four achieved this, bonded well with their baby and enjoyed excellent psychological health. Three women endured vaginal deliveries against their will; all suffered postnatal depression, two suffered symptoms of PTSD and two had delayed bonding with their infants." 131

If your situation is not black and white we would suggest the following activities to help with your decision-making:

Be clear about your concerns and fears (and those of your birth partner). Ask yourself what you feel about:

Which experience do you wish for your baby - being squeezed through the birth canal or disturbed and lifted from your abdomen?

Discuss the choices with your birth partner. They are likely to have worries and questions of their own. In most cases they will be involved in the whole process and it is very important that they are in agreement with the choices that are made. Even with a general anaesthetic caesarean they will still have a role in caring for the baby until you wake.

Once you have all the information you will be in a much better place to make the decision.

Financial Costs What's New

The costs vary significantly depending upon the mode of birth. Figures from the NICE guideline referring to 1989 figures found an instrumental birth to be around £600, unless a post-natal stay in hospital was required in which case it could be as much as £1,300. And a caesarean starting from £1,000 with an extended stays in hospital taking the cost up to as much as £3,500. 27

Of course one thing that these figures give no indication of is the reason for these interventions and the extent to which the extended hospital stay is due to other factors in the birth "Not taking into account these differences may lead to overestimating the cost of CS." 27

Figures presented in a 2006 programme from Woman's Hour on this subject gave new figures of a vaginal birth starting at £935 with a caesarean starting at £2122. Unfortunately the programme did not clarify for the vaginal birth how these costs could increase as medical intervention such as ventous and forceps and epidural became part of the experience.
