Stop 4: Asheville

Taking breech training into the Blue Ridge Mountains of North Carolina …

We had to make a pit stop at a Motel 6 around 11 pm, but my Dad and I arrived in Asheville in time to have grits for breakfast. Asheville is an amazing town with a real ‘alternative’ feel about it, so I was anticipating a very receptive crowd. Already, what was supposed to be one study day on Sunday turned into two, as more doctors wanted to attend but it was already fully booked.

So at Harvest Moon Woman’s Health we had a 4-hour condensed training on Saturday, attended by one board-certified obstetrician, one resident at a local hospital, two family practice doctors from South Carolina, and a handful of midwives. This was followed by the full-day training on Sunday with midwives who came from as far as Tennessee and Virginia. With 39% of the respondents (across all of the six training days) indicating they had NEVER had any training in vaginal breech birth, the need and demand for such training was very strong.

We again discussed the subtle difference between these two ways of performing the manoeuvre often referred to as Frank’s Nudge:

  • Sub-clavicular pressure and bringing the shoulders forward to flex an extended head
  • Pressure in the sub-clavicular space, triggering the head to flex
  • (Walker et al 2016)

The first of these involves rotating the shoulders forward, as described by Louwen and Evans (Evans 2012), minimally lifting the baby, and initiating flexion in the thoracic and cervical spine. This action is often performed with a rocking motion, nudging the aftercoming head around the pubic bone, mimicking the way a head is normally born, in reverse. Mary Cronk used a ‘stuck drawer’ metaphor to describe why rocking rather than steady pressure is sometimes more effective. Participants felt that the description ‘shoulder press‘ is effective for communicating the simpler manoeuvre (#2), where the head has stopped at the outlet of the pelvis. South Carolina Midwife Gayling Fox then suggested the term rock’n’roll manoeuvre for the other skill (#1), more useful where the dystocia has occurred at higher levels of the pelvis. Only in Asheville! I have to admit, the phrase is both fun and functional …

The law of ‘attracting breeches’ was in full swing in the mountains, as OB-GYN Dr David Hayes reported having received multiple enquiries from women seeking support for a vaginal breech birth, just from having hosted this training. In addition to being a sensitive and woman-centred obstetrician, David is an experienced breech catcher, having worked in both high-risk Western settings and abroad with Medecins Sans Frontiers. While he was open to physiological breech methods due to his familiarity with physiological birth in general, he had never attended a breech where the woman birthed in an upright position.

One of the women who contacted him was full-term with her first baby in a frank breech position (both legs extended). David asked if I would attend to support the birth in a teaching capacity, if available. Although we still had a couple more stops on the road trip, I tend to believe what will be, will be … if the stars align in just the right way … I said, Yes!

Tomorrow: Last stop: Atlanta. Or so we thought …

RCOG and Oxford Breech Conferences, October 2014

Screen Shot 2014-10-19 at 17.09.13Well.

It’s been a historic week.

Last Tuesday, 14th October 2014, obstetricians and midwives from around the world converged in the basement of the Royal College of Obstetricians and Midwives (RCOG) in London for a study day on Management of the Term Breech (#RCOGbreech). The day was originally planned to correspond with the publication of the new RCOG guideline, last published in 2006. However, the re-write has been delayed, understandably. Across the country, more and more units are not only raising the level of support for breech, they are supporting women to birth their breech babies in upright positions, something the current guideline recommends women are advised not to do.

The update authors face some tough choices: 1) continue to advise against an increasingly popular practice, alienating many of the few professionals currently supporting breech births; or 2) turn the current state of affairs upside down by … guess we’ll see when it’s published! The RCOG day was opened by the rather marvellous Mr Lawrence Impey, Oxford Consultant in Obstetrics and Fetal Medicine and co-author (with Justus  Hofmeyr) of the 2006 guideline, and Mrs Anita Hedditch, Delivery Suite Senior Midwife and ECV Midwife, also at Oxford. Impey acknowledged the sense of anticipation and slight tension in the room by instructing delegates: “No heckling, and no snorting!

ColleaguesHowever, Professor Deirdre Murphy from Dublin created little controversy with her fair and balanced evaluation of the evidence. Although her analysis was much more nuanced, following discussions, the take-home message was: With experienced support, the short-term risks for breech babies (neonatal mortality, serious morbidity) are probably not significantly greater than those for cephalic babies. Both breech and cephalic babies have increased short-term risks compared to a planned caesarean section (CS). For breech babies, the available evidence indicates that by two years of age, no significant difference in primary adverse outcomes (death and neuromotor delay) is apparent between babies born after planned CS and babies born after planned vaginal breech delivery (PVD). But babies born following planned CS face some increased risk of other medical problems.

Mohajer1Murphy was followed by Mich Mohajer of the Royal Shrewsbury, who presented evidence from her telephone survey about what exactly is happening around the UK for breech. ECV appears to be almost universally offered throughout England and Wales at the moment, although she found significant variations in models of care, with some units offering dedicated breech clinics and other units offering an ad hoc service on delivery suite. She found even more variations in levels of support for vaginal breech birth, with only 27% of units in England and Wales supporting VBD. Mohajer also acknowledged the importance of involving midwives with breech skills, as the facilitation of breech births has always been considered part of midwives’ expertise. These two themes: the importance of a specialist approach through dedicated clinics and ‘breech teams,’ and the value of multi-professional collaboration, were echoed frequently throughout the week.

BiasesAfter a brief break, Dr Leonie Penna from King’s in London presented on ‘pitfalls and pearls’ in delivering the vaginal breech. She summarised a number of common errors and helpful hints, bringing the focus onto the real gap in clinical skills which will need to be closed or bridged in order to reintroduce systematic support for planned breech births. Penna was also very upfront in discussing the reluctance of the obstetric profession to shift away from women on their backs, even with strong evidence of how helpful it is. She drew parallels with fetal blood sampling, which it is now recommended to perform with women in left lateral. With Penna’s talk, it became clear that the discussion is finally shifting away from an assumption of vaginal breech DELIVERY and towards and understanding of vaginal breech BIRTH. Finally, Penna as well emphasised the important role midwives have always played in supporting breech births at King’s.

huggingAfter this, Dr Anke Reitter presented on her experience of being a part of the now-famous breech clinic in Frankfurt, and her MRI data demonstrating how significantly maternal movement affects the dimensions of the bony pelvis. Reitter (@OB_Anke) also discussed how our current understanding of helpful manoeuvres for upright breech birth – especially the first principle of rotation by the shoulder girdle rather than the pelvis – is not new. She showed captivating drawings from historic German and Australian textbooks showing nuchal arms and how to resolve the problem. Thankfully, Reitter will be returning to the UK in June to share her hands-on skills at one of our Breech Birth Network Physiological Breech Study Days.

placentaVisiting speaker Thomas van den Akker, obstetrician and researcher from the Netherlands,  reminded the audience of the RCOG’s responsibility to the developing world. In less resource-rich countries, CS presents a much higher risk to women and their future children than it does in the UK. But the world follows the RCOG’s example and demands the highest standard of care, even when it is inappropriate in that context. Van den Akker also presented data from follow-up studies by the Vlemmix team which demonstrate that per 10,000 babies delivered by CS for breech (compared to planned VBD), there were 26 neonates saved in the first pregnancy (19/7442). However, there were 27 neonates (18/6689) lost in subsequent pregnancies in a policy of trial of labour. Can we continue to recommend that first time mothers avoid a vaginal breech birth, while encouraging them to plan a vaginal breech birth after caesarean section (VBAC) in their next pregnancies?

Jane EvansOver lunch, Jane Evans gave a presentation of the mechanisms of breech labour, and strategies to help when help is needed. She brought along her slide show and doll and pelvis, for those who wanted to make the most of every minute available to learn breech skills.

After lunch, the morning speakers engaged in a panel discussion about how the term breech should be managed. The relaxed mood and support for the option of vaginal breech birth was clearly emotive for some. One obstetric delegate stood up and shared how he had become a pariah among his colleagues for continuing to facilitate vaginal breech birth (VBB), and how he hoped the new guideline would be more clear about how important and appropriate it is to support VBB.

This was followed by talks by Impey and Hedditch about the evidence base, practice and their clinical experience of external cephalic version (ECV). Like many other professionals, I have made a pilgrimage to Oxford to visit their renowned clinic and learn from them and their community midwife colleague, Pauline Ellaway. They presented their most recent statistics, which like others’ (see Grootscholten et al, 2008) show a higher rate of interventions and adverse outcomes for post-ECV babies than babies who spontaneously assumed a head-first position (neonatal mortality = 0.9/1000; not significantly different from 1.3/1000, the neonatal mortality for planned VBD in the Netherlands reported in Vlemmix et al). This is a video from a Dutch team which also use a two-person approach.

keenThis then opened up the discussion in the final afternoon panel to a point I had not previously hoped was possible: The genuine suggestion that perhaps dedicated ECV services should become dedicated Breech services, where women’s individual clinical situations are evaluated and those felt to be good candidates are offered a VBB, while those who are not felt to be good candidates are encouraged to consider ECV. (Selection criteria remain controversial, but this openness is a very good start.) The strong message was that women should have access to a high-quality, experienced ECV service, but this should not be the only alternative to CS.

ECVDr Joris Hemelaar also presented about rates of undiagnosed breech in Oxford, which are over 20% like most places in the UK which do not do routine third trimester scans (which are not recommended by Cochrane. Hemelaar’s point in presenting this information alongside reports on breech/ECV clinics is that we cannot offer women an ECV or detailed counselling about VBB if we do not detect the breech antenatally. However, and my view differs somewhat, as we do not yet have any evidence that the undiagnosed breech is at greater risk in the UK. Most of the available evidence indicates that the undiagnosed breech is far more likely to be born vaginally, at no increased risk. The situation is unlikely to change until more than 27% of UK units support a planned VBB, and until that time, obstetric and midwifery-led units would be wise to put a proactive plan in place so that these births can be managed with a calm, team approach.

Oxford Brookes

As if the RCOG conference was not exciting enough, Senior Midwifery Lecturer Ethel Burns of Oxford Brookes University made the most of international visitors to host a conference on “Breech Birth: Sharing what we know and do, and exploring best practice for the future,” on Saturday, 18th October 2014 (#Oxfordbreech). The day included repeat presentations (for a new audience) from Anke Reitter and Anita Hedditch, and Jane Evans again presented her slides, mechanisms and manoeuvres over lunch; but there were some additions.

Collaborative approachThis day kicked off with Lawrence Impey presenting the evidence base for breech birth, emphasising some of the themes from the previous Tuesday’s conference:

  • In selected women with high quality care baby mortality is probably little different from cephalic presentation, but is higher than ELCS
  • However, there may be a higher risk of obesity, asthma and other serious problems following elective CS
  • Maternal mortality and morbidity is dependent on emergency CS rate but unless this is >50% is likely to be increased with a polity of elective CS. This is particularly important in the developing world.
  • In the long term, there is a small increase in risk of mortality and morbidity to future babies through unexplained stillbirth and uterine scars.
  • Lost skills will mean a higher complication rate for unplanned breech deliveries, be these CS or vaginal

heavy handedImpey was followed by Ruth Sloman, who has recently completed her Masters in Midwifery at Oxford Brookes. Sloman used focus groups to look at midwives’ knowledge and experience of breech births. I really enjoyed this presentation, and some of Ruth’s themes resonated with my own research, especially the value of video footage in helping professionals to learn when hands-on experience is difficult to come by, and midwives frustration at witnessing vaginal breech deliveries poorly managed and the lack of choice available to many women.

nuclearAfter the break, the conference continued with Dr Andrew Bisits, FRANZCOG of Sydney, Australia. Bisits’ sensitivity to women’s experiences has made him beloved of women and midwives across the globe, and his long-term commitment to supporting vaginal breech births has gained him knowledge and experience exceeding most obstetricians working in 2014. Crucial to Bisits’ talk was a recognition of how important the experience of attempting a vaginal breech birth is to some women. He also encouraged us to recognise that moderate risk-taking confers psychological benefits. Although Bisits’ talk included much more than I can summarise here, a final important point concerned the ‘atomic reaction’ which usually follows adverse outcomes in breech births, and knee-jerk responses usually preclude any genuine learning from these events. If we are to improve the safety of breech birth, it is vitally important that we learn from adverse outcomes by reflecting on them in an open and enquiring, rather than punitive way.

enablingReitter and Bisits are of course not only two of the most highly experienced breech practitioners in the world, they are passionate advocates for the use of upright positioning. Reitter’s clients birth mostly in all fours/kneeling positions, and Bisits’ clients commonly use a birthing stool. Their view is that it is not so much the position, as the ability of women to move spontaneously and assume the position of her choice, which matters most. The mood of both days indicated that this point has been well and truly made and heard by those writing the new guideline. The question became not so much whether upright positioning would be acknowledged as a legitimate approach, but whether or not it will continue to be considered in any way ‘alternative’ in the new guideline.

getting itBetty-Anne Daviss visited from Ontario, presenting an encapsulated history of the women’s movement in Canada, and how this has influenced the progress they have made with breech birth. She explained the way in which the Canadian-born Coalition for Breech Birth worked with sympathetic doctors and midwives to reintroduce the choice of VBB. Remarkably, Daviss has succeeded in gaining privileges to attend VBBs in her local hospitals, and currently supports approximately 1-3 women per month to achieve their goal.

anticipatoryI also presented my current research concerning how practitioners learn breech skills. We need to accelerate this process if we are going to increase support for planned vaginal breech birth within the current risk-adverse maternity care culture. I’m looking forward to sharing more of this in publications as the research progresses, so watch this space! My presentation also highlighted the standard of care when it comes to maternal birth position for healthy women. NICE’s evidence-based and woman-centred approach is clear:

  • Women should be discouraged from lying supine or semi-supine in the second stage of labour and should be encouraged to adopt any other position that they find most comfortable. (1.7.7, current Intrapartum Care guideline)

Screen Shot 2014-10-19 at 17.09.59If policy-makers are now acknowledging that VBB carries a similar risk to cephalic birth in experienced hands, then those who continue to advocate a maternal birth position (lithotomy) which deviates from the current standard of care should present evidence as to why they are doing this, rather than the other way around. Experience alone may be enough to explain it for those who have continued to safely facilitate VBDs, but the next generation and those who have taken a 14-year hiatus would do well to learn the new upright techniques as part of their standard training.

Screen Shot 2014-10-19 at 15.30.44If the authors of the new RCOG guideline walk the walk as well as they have talked the talk in the past week, some major changes are a-foot. But policy changes are only a small part of what happens on the ground, evidenced by the fact that the RCOG has recommended  the choice of VBD be offered to women since 2006, something that is clearly not happening universally in the UK. A major cultural shift is required, but these two events suggest that the shifting has indeed begun.

Dr Susanne Albrechtsen and the Big Breech Picture

Dr Susanne Albrechtsen, obstetrician and epidemiologist from Haukeland University Hospital in Norway, spoke at a Breech Birth Network study day in Kilmarnock on 14 February 2014. Read about the day.

Epidemiology is the study of patterns, causes and effects associated with conditions of disease or health in defined populations. (Information from the BMJ.) For our purposes, epidemiology helps us to understand what happens with breech presentation in large groups, enabling us to ask and answer questions such as:

  • What factors are associated with an increased incidence of breech presentation?
  • What are the characteristics of the hospitals in which breech presentation is most/least likely to be delivered vaginally, or to result in a good outcome?
  • What are the long-term effects associated with of breech presentation, and do they vary by mode of delivery?

Albrechtsen has been researching breech presentation for many years. In a 2004 systematic review, Albrechtsen and her team discussed the literature concerning mode of delivery for breech presentation. The article illustrates well why the external validity of the Term Breech Trial (TBT) is questionable: many centres have demonstrated considerably lower neonatal mortality and morbidity levels associated with vaginal breech birth (VBB) than those the TBT reported. They also discuss the difficulties of repeating the TBT trial design in locations with good results for breech-born babies: the lower your perinatal morbidity and mortality, the more recruits you need in your study to reach statistical significance. In Norway, Albrechtsen’s team calculated each arm of a randomised controlled trial (RCT) would require 10,000 members for two-sided testing. Clearly impractical. This review also raises reasonable questions about the research base behind the practice of external cephalic version (ECV). Although the available research suggests that the practice of ECV reduces the rate of CS for breech, there is no clear evidence that it reduces perinatal mortality. (You can read an earlier systematic review on this point, if you can read Norwegian.) We should be approaching all options – ECV, VBB, and CS – as reasonable. Albrechtsen and co. have also been making the point for some time that caesarean section does not reduce the rates of cerebral palsy (CP) for breech-presenting babies. Sadly, rates of CP among breech-presenting babies are significantly higher than for vertex babies, regardless of the mode of birth. This is because CP is most often the result of an antenatal insult (infection, growth restriction, etc.) rather than the birth itself. This has recently been confirmed in a systematic review and meta-analysis by another team. The excellent national databases kept in Norway enable these kinds of ‘big picture’ views on the outcomes for breech babies. Albrechtsen has also contributed to a significant amount of literature concerning patterns in the occurrence and recurrence of breech presentation. This includes research on the familial predisposition to term breech delivery, demonstrating that  factors influenced by genetic inheritance come from both mothers and fathers. Additionally, she has looked at the effect of having a breech baby on subsequent pregnancies, covering the recurrence of breech presentation (common), rates of subsequent pregnancies and interpregnancy intervals. Understanding that having a breech baby appears to affect a woman’s attitude toward future pregnancies means that we can attempt to provide more supportive counselling in current breech pregnancies. The extensive Norwegian birth registers also enabled her to look at outcomes among siblings, demonstrating that women with recurring breech presentation represent a lower risk of adverse perinatal outcome, whereas a current breech presentation with no previous history of breech presentation is at higher risk.

“Perhaps heterogeneity exists, implying that recurring breech presentation for some women represents a normal condition with no increase in perinatal mortality” (p 775).

This article adds to our understanding about how confounding factors both contribute to breech presentation and to the increase in poor outcomes among breech babies, regardless of mode of delivery:

“The evidence is compelling that fetuses presenting as breech are affected already to a higher extent before delivery because morphologic and functional damage is more common in these fetuses” (p 775).

Routine CS is likely to improve the rate at which this minority of more vulnerable babies survive being born; but it cannot undo what has already been done. This is supported by the long-term outcomes within the TBT. We should be approaching all options – ECV, VBB, and CS – as reasonable. (This is not to say that breech-presenting babies are likely to be abnormal. The vast majority of them are perfectly normal, assuming a breech position due to genetic or accidental factors. But it does explain why, despite a widespread policy of CS for breech, we still see increased adverse outcomes for babies delivered in a breech position. And why becoming comfortable with the fact that this will occur regardless might help us improve outcomes for more women, who can reasonably choose a VBB.) Albrechtsen’s work on Secular trends in peri- and neonatal mortality in breech presentation; Norway 1967-1994 gives us some insight into why breech presentation has been the subject of fierce and passionate position-taking. In 1967-1976, 9.2% of babies delivered in breech presentation after 24 weeks died; that is almost 1:10. This figure declined significantly throughout subsequent decades, even after the CS rate stabilised, probably due to improved obstetric and neonatal care. (Preterm breech babies are at greater risk than term breech babies, born after 37 weeks.) As someone who spends many hours answering women’s questions – such as, “Why is my baby breech?” – I am grateful for Albrechtsen’s work. Some believe the TBT was the last word on the topic of breech delivery. Others continue to believe that we have much more detail to understand in order to support women well through the complex and emotional journey of a breech pregnancy.
