Claire Reading sharing her skills
This Tuesday, 1 March 2016, Breech Birth Network travelled to Portsmouth again. The guest speaker was lovely doctor Ms Arti Matah, who spoke about an obstetrician’s view of vaginal breech birth, and led a lively discussion around whether the breech team / care pathway model might work for Portsmouth. Watch this space! I am incredibly impressed with the commitment Portsmouth midwives have shown to developing sound breech skills to support women who choose to birth their breech babies actively.
The skill which captured the group’s imagination most was how to resolve a situation where the head is extended and impacted at the inlet of the pelvis. My research suggests that identification of optimal mechanisms is a core skill for practitioners attending breech births. Therefore our approach to teaching this skill is:
- Identification of optimal mechanism — The aftercoming fetal head normally rotates to the oblique/transverse diameter as it enters the pelvic brim, just like the cephalic-presentation head does when engaging.
- Identification of deviation from optimal mechanism — In this complication, the fetal head is pinned in the anterior-posterior diameter, with occiput anterior, over the maternal symphysis publis, and chin or brow on the sacral promontory. The bottom of the fetal chin is felt like a ‘bird beak,’ pointing towards the sacrum. The maxilla bones are difficult/impossible to reach, so flexing the head using the usual techniques will be a challenge.
- Restore the mechanism — See below.
The RCOG guideline suggests delayed engagement in the pelvis of the aftercoming head should be managed using one or both of the following techniques:
Suprapubic pressure by an assistant should be used to assist flexion of the head. Given our understanding of the head as impacted at the pelvic brim and our goal of restoring the mechanism by rotating the head to assist engagement, we suggest that the goal of suprapubic pressure should initially be to encourage this rotation. This mirrors the understanding we have of suprapubic pressure to resolve a shoulder dystocia by rotating the impacted shoulder off the symphysis pubis. Forcible pressure on an impacted fetal head is unlikely to be beneficial for the baby.
The Mauriceau-Smellie-Veit manoeuvre should be considered, if necessary, displacing the head upwards and rotating to the oblique to facilitate engagement. We use a doll and pelvis to explore why this elevation and rotation prior to re-attempting flexion is necessary. Watch the video below to see this demonstrated.
When a woman is birthing her breech baby actively, we facilitate the head to enter the pelvis using the same principles. Watch the video below, where Midwife Olivia Armshaw is teaching how to intervene in the case of an extended head at the inlet, when the woman is birthing on hands/knees. In this video, the midwives are discussing how maternal movement – in this case, the woman shuffling her bottom back towards the midwife slightly – helps to elevate the head off the pelvic inlet to facilitate engagement, a technique we learned from the midwives of Sheffield. The principles – elevate, rotate & flex the head – are the same.
Thank you to the Practice Development Team at Portsmouth for organising the day. And thanks to the following midwives for assisting with the day:
- Claire Reading, midwife in Somerset, who shared her breech experience gained working abroad, and facilitated one of the hands-on stations
- Olivia Armshaw, midwife from Gloucester, who facilitated one of the learning station and presented on the process of developing a breech team in her local area
- Tess McLeish, midwife from Lewisham who helped the day run smoothly
Our one sadness on this study day was that we were not joined by any of Portsmouth’s obstetric staff, aside from Ms Arti Matah, who needed to leave early because she was good enough to present at the study day following a night on-call. Across the UK, midwives are trying to engage their obstetric colleagues in a discussion about how to improve things for breech babies and their mothers, and we really need more doctors to come to the table for that discussion to result in a service which is as safe as possible.

BONUS was meeting and relaxing with Midwife Jenny Hall in Portsmouth after the study day!

Feedback from the Study Day:
“the group work was excellent Overall I thought the day was was a good balance of theory to practical”
“very interactive. realistic rather than textbook. real life experiences.”
“perfect study day. Interesting and kept my attention all day!!!”
“visual with the film clips and hands on with the doll and pelvis. Was very good to see normal and abnormal films and great discussion with colleagues to share experiences and what to do in that situation.”
“I also thought Shawn’s attitude to breech was very refreshing. I half expected it to be a bit like “you can have a vaginal breech no matter what”. this was not the case. She had a very safe and sensible approach.”
