Diabetes – oxytocin less effective for these women

For years now diabetes has been known to complicate birth for many women and unfortunately the incidence of ‘type two diabetes’ is increasing as our weight as a nation increases.

According to researchers at the University of Liverpool approximately 60% of diabetic women (including those who develop diabetes during pregnancy) will be unable to complete labour naturally and will require a caesarean.

Until now the reason for this has not been fully understood. Researchers have found “that contractions in women who had the disease were not as strong as those in non-diabetic women…Calcium levels in the uterus should rise to allow the muscle to contract effectively. Researchers found, however, that in women with diabetes, calcium levels are significantly reduced. “ University press release

While the result itself is useful in understanding why this is happening to so many of the 35,000 women that have diabetes during pregnancy every year, the implications for the management of diabetic labours is perhaps even more significant.

Researchers found that when uterine tissue of diabetic women was treated with oxytocin (a drug often used to assist labours that are experiencing difficulties) it was found that contractions “failed to reach the same levels of contractility as in non-diabetic women.” While more research is on-going, this finding does suggest that advice to women as they plan their birth ought to consider caesarean birth as a prophylactic option and more specifically for those wishing to attempt labour that the door is left open to switching to a caesarean during labour earlier such that they can have a caesarean before real signs of distress result in ‘critical’ surgical intervention.

Words of wisdom from Betty Parson’s – childbirth guru

Betty died this week but left wonderful words that we would all do well to take with us into our births and into life in general…

“It is the attitude of mind that is the most important thing of all…to be able to go into labour [or indeed any type of birth or life situation] with the positive attitude ‘I am doing’ rather than ‘it is being done to me’.”

Options after a previous caesarean

I frequently get asked about options following a previous caesarean. Unfortunately the answer is not straightforward. Hospital policies continue to influence things both overtly in terms of encouragement towards VBACs (Vaginal Birth After Caesarean) and whether or not there is a ban on requested caesareans, but also less overtly through their common practises e.g. their approach to induction / tolerance for the length of 2nd stage labour etc. In addition to hospital policies there are also differences of opinion among practitioners which can alter the options you may be presented with on any given day.

It is very important therefore that you know your rights. “Calmly discussing your options, knowing what can and cannot be insisted upon and the difference between a ‘required’ and ‘suggested’ caesarean, puts you in a strong negotiating position.” ‘Caesarean Birth: A positive approach to preparation and recovery’

Trying to avoid a caesarean:

For those wanting to avoid automatically having another caesarean this is increasingly possible, always assuming of course that the reason for the first caesarean is not likely to recur in each pregnancy. Hospitals are being actively encouraged to support VBACs and NICE guidelines state that “Women have the right to choose VBAC.” (pg 22)

Some hospitals offer special clinics aimed at encouraging just this. It is worth asking what is available at your hospital and local doctor surgery as these classes can provide lots of information and support about how to manage your pregnancy and labour such that you may increase your chances of achieving a vaginal birth.

If you continue having difficulty gaining agreement for a VBAC it is worth knowing that the NICE guidelines are very clear on this “For the process of seeking consent to be meaningful, refusal of treatment needs to be one of the patient’s options. Competent adults are entitled to refuse treatment even when the treatment would clearly benefit their health. Therefore a competent pregnant woman may refuse CS, even if this would be detrimental to herself or the fetus.” (pg 71 )

That said it is very important that you understand why a VBAC is not being supported this time round. Just a few examples of the reasons are: there may be genuine medical indicators meaning this is not the safest route for this pregnancy, the practitioner is less confident with VBACs (in which case you may want to consider alternative providers) or you are hearing a practitioners personal opinion coloured by fears of scar rupture rates. I dedicate a whole chapter in my caesarean book to the many things you can try in order to help influence your chances of avoiding another caesarean. In particular I address the mis-information often presented to women on scar rupture rates so that you can make an informed decision about the level of risk yourself.

Requesting a repeat caesarean

For those preferring to have another caesarean this will, in many cases, be dependent upon the opinion or policy of those responsible your care. Some hospitals do not permit maternal request caesareans, even after a previous one, if there is no medical need. (A previous caesarean no longer constitutes a ‘medical need’, unless as already mentioned, your first caesarean was for reasons which are likely to recur in this pregnancy). Where your request is being refused you will need to seek a second opinion and may even (if the opinion is a hospital policy rather than the personal opinion of the practitioner you are talking to) need to approach a different hospital.

The NICE guidelines are very clear on this:

“Recommendation 39: An obstetrician has the right to decline a woman’s request for a CS. If this happens, they should refer the woman to an NHS obstetrician in the same unit who will carry out the CS.” NICE guideline (pg 12)

However the guidelines are just that – ‘guidelines’. NHS hospitals are not required to follow them to the letter so you may find you are requesting a caesarean at a hospital where maternal requests, in the absence of any medical need, are indeed banned in which case you will need to seek an alternative place to deliver.

I talk in a lot more detail in my caesarean book about things to know if you want to avoid or indeed plan a caesarean. In both cases you may find significant barriers are put in your way, but there are quite a lot of things you can do to help you case.

NICE still have a way to go on caesarean guidelines

As a campaigner and contributor during the recent review of the NICE Caesarean Section Guideline I was pleased to see many of the changes and clarifications subsequently made in the latest version. However they did not go far enough and csections.org will continue to campaign for the following:

  • acceptance of informed choice as a valid indicator for maternal request caesareans (the document as it currently stands still makes this ambiguous, referring primarily to instances of tokophobia therefore failing to recognise the full spectrum of reasons why women may request a caesarean)
  • clear statements about the scope of antenatal education in relation to caesarean birth (the document talks about the importance of education in relation to the risks and benefits of the procedure and improved understanding of the surgical procedure). The guideline does not address the absence of balanced antenatal education on all aspects of caesarean birth as a standard part of birth preparation
  • allow women to gain early agreement for a planned caesarean, e.g. well before the current common practise of week 34. Women suffering from tokophobia or who have on-going medical indicators that suggest a caesarean delivery should be able to progress through their pregnancy without the additional stress of having to wait to see if their consultant will agree to a caesarean birth
  • removal of the assumption that women who request a caesarean should be provided with support to ‘change their minds’. Some women wish to make an informed choice in favour of a planned caesarean after careful evaluation of the risks of caesarean versus vaginal birth
  • clarification that a woman who has had a caesarean agreed but goes into labour prior to the surgery date, will have her planned caesarean upheld and conducted as soon as possible
  • ECG wires be attached to the woman’s back rather than her chest to facilitate skin-to-skin contact and breastfeeding while in theatre (see Natural caesarean)
  • post-operative debriefs are automatically offered to all women following their birth. This service is only offered sporadically across the country yet it is particularly important for women planning more family that they understand their caesarean birth and its implications for future pregnancies
  • standardised reporting techniques such that types of caesarean and their reasons can be more clearly distinguished and risk/benefits rates more accurately allocated (that maternal request caesareans be specifically identified and separated from those planned caesareans where obstetric advice has ‘suggested’ a caesarean may be preferable
