I always smile when people say, “It’s all well and good to support natural breech birth, but what happens if the head gets stuck?” Those of us who are supporting woman-centred, modern breech birth take an equally realistic view about the need to intervene in a skilled and confident manner when help is needed, although we are probably more realistic about the frequency with which such intervention is required. We also obsess about creating trusting relationships and environments which facilitate more spontaneous, easier births, with the end result that we need to use our skills less often.
However we sometimes rely on these skills to achieve a safe outcome. Therefore we share our experiences with others, for when they might be needed. And we know that supporting others to confidently support more breech births will create new knowledge which will in turn help us to improve our own practice.
Where does this knowledge come from? Hint: not Randomised Controlled Trials. One of the many ways midwives create knowledge about practice is by listening to each other and listening to women. For example, in the training aid linked above, one of the options involves assisting a woman who is on all fours to become straight upright on her knees, and applying suprapubic pressure. This is how my own personal learning about that happened (participants not identified to maintain confidentiality):
The baby’s head was hyperextended at the time of delivery, but not before. Woman on all fours, no progress with the next contraction, no spontaneous movements from the baby to assist his own flexion. Neither the midwife managing nor the Registrar who was supporting could reach the baby’s chin, just what felt like a bird beak (the lower jaw bone) pointed up to the sky, so Mariceau-Cronk was not an option. All present were fairly inexperienced, and no training aids were available, so the decision to get the woman upright was instinctive. The decision to apply suprapubic pressure while doing so was based on RCOG guidelines about how to help when the woman is in lithotomy, transcribed to the current situation. The occiput was felt during suprapubic pressure. Then suddenly the baby’s head dropped into the pelvis, and was immediately born wearing his placenta like a hat. Several minutes of resuscitation were required. Baby recovered quickly and well.
Following on from this story, I returned to the sources I use over and over again. Anne Frye’s Holistic Midwifery described how some midwives get the woman upright (for breech and shoulder dystocia) because this tightens the abdominal muscles, promoting head flexion. So someone else has a theory for how it works. There is also increasing radiological evidence that when upright or prone (e.g. shoulders, pelvis and knees in a straight line), the pelvic inlet is largest, while squatting significantly enlarges the mid-pelvis and pelvic outlet. The strategy of assisting the woman to move into an upright posture and use suprapubic pressure may have resulted in an even better outcome if performed earlier, as soon as the dystocia was identified.
Once you begin to see the patterns, they emerge in the stories you immerse yourself in. Reading Jennie Clegg’s story about her ‘Breech VBAC at home,’ I found this:
The next push I gave it everything I had and rumping happened very quickly followed by the body; the relief of the pressure was immense. Two sharp sensations happened which were the legs releasing, I remember looking through my legs and seeing a little body! Then there were a few sharp uncomfortable movements which were caused by the baby wriggling its arms out. My contractions at this point had stopped.
Debs could see no chin on the chest to examined me and found the head to be extended. An ambulance was called and Debs started manoeuvres to birth the baby. No movement was felt so I was encouraged to change position and Michelle tried nipple stimulation to get contractions coming. Michelle and James helped me to stand, Debs attempted head flexion, movement was felt and I was encouraged to push, baby was born immediately followed by the placenta! (Midwifery Matters, ISSUE 135, Winter 2012)
This scenario was slightly different, but maternal movement was again helpful. Jane Evans, a midwife with many years of breech experience, writes and talks about how her understanding of the physiology of breech birth has been informed by listening to and close observation of women (Evans 2012a, Evans 2012b).
Listen to women. Listen to midwives. Share your stories. Share your skills.
