The art of vaginal breech birth on all fours

I recently discovered a new article about upright breech birth: a clinical case report titled The art of vaginal breech birth at term on all fours by Wildschut, Belzen-Slappendel, & Jans. (PDF here).

This article describes a case where a woman planning a hospital birth called her midwife to her home when labor began. Soon after, the midwife discovered an undiagnosed frank breech and the mother had a strong urge to push. Sensing there was not time to transport, the mother decided to remain at home. (This birth took place in the Netherlands, where home birth is still quite common.)

The case report includes a detailed report of the birth. Gorgeous, well-lit photographs document the spontaneous birth of a breech baby with the mother on hands & knees. The birth was completely hands-off except for gentle assistance at the very end. Here are a few sample pictures from the article:

The authors (one of whom was the attending midwife) discuss the challenges of undiagnosed breech presentations, the evidence for all-fours positioning in breech births, and the ongoing debate about whether cesarean or vaginal birth is best for breech presentations. When the authors submitted their manuscript, the Frankfurt study on upright breeches by Louwen et al (full text) had not yet been published; the authors cite a smaller study on upright breech birth by Bogner et al (full text).

At the end of the article, the authors comment:
It remains important that clinicians and midwives are prepared for vaginal breech births. Prerequisites for the effective management of vaginal breech birth include the clinical finding of an average-sized baby (defined as a fetal weight estimate between 2500 and 4000 g), maternal cooperation, and the right mindset of the attending clinician or midwife. In fact, management of a vaginal breech birth is a skill; its safety relies on the competence of the attending health professional. The intrapartum attendant should also be composed and have sufficient confidence and courage to manage vaginal breech birth. For this reason, regular hands-on training sessions with scenario teaching, videos and/or image-based lectures, such as presented in this article, are advocated for health professionals to be acquainted with the various maneuvers for vaginal breech birth.
Undiagnosed breeches still occur regularly. When the attending physician or midwife is not skilled and comfortable with vaginal breech--as is too often the case today--this can pose a risk to both mother and baby. All the more reason for midwifery & obstetrics training programs to continue teaching vaginal breech skills.

For another example of an undiagnosed breech late in labor, read Naomi Carslile's experience while working in a UK hospital. Carlisle, a student midwife, narrates a successful (although much more stressful and anxious) vaginal breech birth. Wildschut and his co-authors show how a well-prepared, calm, and confident birth attendant can make the best of the unexpected.

Ken Johnsson & Betty-Anne Daviss: The Frankfurt Study

First Amsterdam Breech Conference, Day 2
Ken Johnson & Betty-Anne Daviss
Rethinking the Physiology of Breech Birth: 
A Cohort Study in Frankfurt, Germany, 2004-2011

Betty-Anne Daviss opened the session by remarking that this study has been a long time coming; she’s been working on it since 2008. It is a collaboration between Frankfurt and Ottawa involving Frank Louwen, Anke Reitter, herself, and her epidemiologist husband Ken Johnson.

from Spinning Babies
When Betty-Anne and Ken spoke in July 2016, the manuscript had not yet been published. It is now available (without cost) in the International Journal of Gynecology & Obstetrics: Does breech delivery in an upright position instead of on the back improve outcomes and avoid cesareans?. If you scroll down to "Supporting Information," you will find additional tables and a video showing a hands and knees breech birth at the Frankfurt clinic.

B-AD: Research over the last several decades has focused largely on comparison between vaginal birth and elective cesarean section (ECS), and almost no focus on how to improve vaginal breech birth (VBB). She finds that sad. Most of the large registry studies (such as the ones done in the Netherlands, Canada, or the U.S.) appear to have a higher neonatal mortality and/or morbidity with VBB than with ECS. But the registry studies do not capture the details that the cohort studies do.

There are other problems. In Canada, when Lyons et al published their registry study, the conclusions read that the neonatal mortality and morbidity rates were higher with vaginal breech birth. What the abstract did not make clear was that because the outcome measure was reported as a composite variable. Although the two outcomes were reported together as "higher," it was only the morbidity, not the mortality, that was higher. In fact, when she and Ken went to the actual table, the neonatal mortality (NNM) was clearly reported as "0" and the morbidity was, no doubt, not long-term (as in the Term Breech Trial). But if you only look at the abstract and can't wade through the real meaning of the study, you get terribly fearful of vaginal breech birth. And that fear is difficult to undo.

Betty-Anne suggested that we look at cohort studies done in units, like in France, Belgium, Dublin, Newcastle, Norway, and Frankfurt. In all of these places--with skilled attendants, good screening, and protocols--almost invariably the difference in NNM is very negligible.

Today she and Ken are presenting what it looks like to compare two kinds of vaginal birth. It wasn’t an intention-to-treat study; rather, it compares what actually happened. For more understanding of concerns about relying only on RCTs such as the Term Breech Trial and the history of some of the breech research, refer to Evolving Evidence Since the Term Breech Trial: Canadian Response, European Dissent, and Potential Solutions.

KJ: (Next, Ken presented some information on the premature breeches, which they excluded from the study, but were interesting nevertheless.)

The Frankfurt study included 750 term breeches. 42% were scheduled cesareans; half of those cesareans were by the mother’s choice. The Frankfurt cohort had a high number of primips. Most of the vaginal breech births ended with the mothers upright. They also looked just at the last 2.5 years at the clinic, since they were almost exclusively doing upright births at that point. With mothers exclusively upright, they saw slightly higher success rates.

B-AD: This is an observational cohort study, not a randomized controlled trial. We are looking at what is, not at what’s planned. That is, the cohort study describes what has happened at each birth in the natural process of a particular delivery unit, without instigating or removing parameters, as with the randomized controlled trial. Observational data in a unit can thus be very useful and has some merit of itself that can be more useful than randomization.

But it does raise the question: how do people decide what position they end up in? We explain that in the study.

KJ: Having a woman upright resulted in fewer maneuvers. Forceps and episiotomies were never needed in any of the vaginal breech births.

B-AD: We didn’t collect information about fundal pressure in the database, which is actually used frequently, so that would be useful to do in the future.

KJ: Upright maternal positioning resulted in fewer neonatal injuries and a shorter 2nd stage of labor. How do they define 2nd stage in Germany? It starts at full dilation--not at the onset of spontaneous maternal pushing--so it includes a latent stage. This explains some of the longer 2nd stages recorded in the Frankfurt study.

The Frankfurt study used the definitions of fetal and neonatal mortality & morbidity in the PREMODA study. This allows us to compare the Frankfurt data to the PREMODA study and to the TBT (upon which PREMODA was based).

B-AD: This database is incredibly useful. We need to have more of these databases to amplify this area of knowledge. Observational data in cohort studies is really valuable to individual hospitals so they know what is going on and to compare notes with other units. Collect your data in your unit!

Articles about vaginal breech birth since the Term Breech Trial

Below is a curated list of articles about vaginal breech birth since the 2000 Hannah Term Breech Trial. This is not a comprehensive list, but rather a starting place with some of the more influential articles and studies that have shaped the conversation about vaginal breech birth.

I have not included articles about External Cephalic Version in this list, although ECV remains an important part of managing term breech presentations.

I put this list in chronological order, beginning with the Term Breech Trial. You will also benefit by concurrently reading my breech conference summaries from Ottawa (2009), D.C. (2012), and Amsterdam (2016).

Many thanks to Dutch midwife Miriam Benschop, who is writing a thesis on breech and designing a decision aid for women with breech babies. She contributed many of these references, and I added others that I thought were important.

If you have other studies to suggest, please comment below or email me. I'd be happy to add to this list.
