FinallyPregnant - ECV stands for External Cephalic Version. It's where a Dr tries to turn the baby manually while it's still in your uterus. The mother will often (but not always) be given drugs to relax the uterine muscles before hand. The experience varies on a case by case basis - some women describe it as just a bit uncomfortable while for others it's very painful. Success rate is about 50% on average, but varies with the skill of the practitioner, the position of the baby and an assortment of other factors.
I think NICE guidelines recommend offering an ECV at 37 weeks if the baby is confirmed breech. From a developmental point of view you want to leave it as close to term as you can, as a small number of babies will get so distressed by the procedure they need to be delivered by CS immediately. But the later you leave it the larger the baby is likely to be and the more likely the mother is to go into spontaneous labour (which the NHS generally seem to see as a Bad Thing).
BTW, DD was born just about a year ago as a footling breech at home with IMs at 41+3 weeks.
The whole "CS is safer for breech" can of worms... Ah yes! The current NHS policy to recommend CS for breech babies is primarily based on a study commonly known as the Term Breech Trial, published in The Lancet in 2000 by Hannah et al and entitled "Planned caesarean section versus planned vaginal birth for breech presentation at term: a randomised multicentre trial" (the full text is available for free if you register on the Lancet's site). This study seemed to find that a planned CS gave statistically better outcomes for mother and baby than a planned vaginal birth. On the back of this, most Western countries started delivering the vast majority of their breech babies by CS almost overnight.
Unfortunately, the paper has an alarming number of fairly fundamental flaws, to the extent it's one of the worst pieces of research I've ever had the misfortune to read. These flaws encompass
- the design (comparing planned rather than actual mode of delivery),
- the inclusion criteria (in order to be included centres needed to deliver a certain %age of their breech babies vaginally - to get included some tripled their vaginal birth rate over night. If they were confident to birth all these breech babies, why such a big increase?)
- the execution (despite the guidelines indicating attending practioners for VB should be skilled in breech, there are indications this was not always the case)
- and the analysis (babies that died from causes obviously unrelated to mode of birth included in statistics).
The points I've highlighted are just a few of the issues that have been raised since the report was published. When taken en masse there are so many flaws that are so basic a number of papers and/or letters have been written recommending that the conclusions of the Term Breech Trial should be discounted immediately. Unfortunately this hasn't happened and most Dr's still see a breech presentation as abnormal. If you can find an experienced midwife they're far more likely to look on breech as an unusual variation on normal, but experienced midwives are getting harder and harder to find - there's a real risk that the skills required to birth breech babies safely will die out . And everyone agrees that a CS is a safer option than trying for a vaginal birth without the necessary skills on hand.
My experience of breech and the NHS was that as soon as breech was confirmed I was sent off to see the consultant, who gave me an option of an ECV or a CS. When pushed they said that if I really wanted I could try for a vaginal delivery, but it would be Dr led, in theatre, in stirrups, with a big pair of forceps and a large audience - there is a HUGE difference between a midwife led vaginal breech birth (a la Mary Cronk) and a Dr led vaginal breech delivery. I think if I'd talked to the midwives themselves I might have got a different version, but by then we were already leaning strongly towards IMs and homebirth so we didn't persue that line of enquiry. We also declined an ECV, due to the size of the baby and her position.
To my knowledge there is NO research (good or bad) that compares a vaginal breech birth with either a vaginal breech delivery or a CS.
When we were discussing things with our midwives they were adamant that if a vaginal breech birth is to go ahead you should have a normally developed, term baby and the labour should start completely spontaneously and progress naturally. If either of these fail to happen it's a good indication that there's a problem and a CS is the safest way to get the baby into the world.
The other Big Risk that Drs like to throw into the ring when you talk about birthing breech babies vaginally is the whole "head getting stuck" issue. If you talk to experienced midwives, this just doesn't tend to happen with normal, term babies. The two scenarios where it is talked about are where the baby is pre-term (more likely to be breech, and at earlier stages of development there's a discrepancy between the size of hips and the size of the head which tends to disapear at term), or where too much of a hands-on approach is taken (causing the woman's perinuem to contract before the head is delivered).
If you don't want a CS and the baby doesn't turn, start talking to people now. Ask to talk to the Head of Midwifery at the hospital and ask about their experience - I have heard of wards re-working staff rotas to try and make sure an experienced midwife would be available so it is possible. If you get no joy at the hospital where you're booked you could look at other local hospitals. Talk to AIMS and ask for advice. If you're beligerent enough it is possible to work miracles (for example I heard of one lady that managed to get her PCT to pay for an IM for her breech birth - it may not be common but how much of that is because people assume it's a non-starter?)
Sorry that's such a long reply - anyone that's made it to the end deserves a medal! And just to finish, I don't believe that all women with breech babies should try and birth them vaginaly. I do think that it's an option that isn't often presented by the NHS and so a lot of women don't feel they have a choice, and that just isn't fair.
Whatever happens, good luck and I hope you have a good birth experience
