Clinical Trial Summary
This qualitative study evaluates the acceptability of positioning pregnant women in labour in
an optimized position, which consists in the hyperflexion of the legs and the loss of the
lumbar lordosis. Twenty patients in situation of dystocia will adopt the described position
for a limited amount of time.
Description:
Recent data brings out that the Caesarian Section rate in Switzerland is quite high, reaching
33.4 %. Though, the reasons to this increasing amount of CS are not fully known. Therefore,
it is absolutely necessary to expand the existing knowledge in different fields, including
the biomechanics of childbirth. Numerous CS are performed in response to an obstructed
labour, especially when the foetus does not engage in the pelvis near full dilatation. In
order to manage such situations, midwifes currently position parturients in pragmatic
postures. Although not verified by data, this care management suggests that it is possible to
impact the position of the bone segments at stake for vaginal birth including pelvis and
lumbar spine and to promote the descent of the foetus through the pelvic inlet plane. In his
PhD thesis about vaginal birth biomechanics, Desseauve et al investigated this area and found
out that an optimized position similar to the squatting position (hyperflexion of the thighs
and loss of the lumbar lordosis) could be close to the perfect delivery position in terms of
ability for the foetus to go through the pelvic inlet plane. Although these findings are
encouraging, it is yet to be confirmed in clinical practice, particularly when a dystocia
occurs. Prior to doing that, it is though necessary to validate the optimized posture in
terms of acceptability in a qualitative clinical study. In this study, fifteen to twenty
parturients who respond to the inclusion criteria and whose foetus does not engage in the
pelvis near full dilation will be asked to adopt the optimized position for a twenty minutes
period. The investigator will then consign information reflecting the progress of the labour
on a data sheet.
