Hi Jo:
I never cease to be amazed at how this 1cm/hour or
Freidman's Curve continues to be applied rigorously to women in labour. Coming
from the homebirth environment to the hospital one, at least to my mind it
is hurdle often before women. As a midwifery student this view of labour was
presented to us as the statistical norm(for hospital birth) and as such had
standard deviations on either side of it that were still normal and they were
different for both multips and primips. Of course in a "slow" labour we have to
always be looking out for a truly obstructed labour, maternal, and fetal
exhaustion: that is where our skill comes in. Similarly we have to be mindful of
truly preciptitous births as opposed to those that are just faster than the
"norm".
Often in birth, complicated ones in
particular, the true picture only presents itself with hindsight.
It can be a delicate art discerning a stalled labour from a slow but
progressing one. Similarly we have to resist the urge to normalise everything
and accept the persistent OP (or the deep transverse) baby as one who wont
come out vaginally and be thankful for the option of caesarean birth. Please
note I said PERSISTENT< most of these babies will eventually turn and then
descend and come out in 2 to 3 pushes: it often takes time, many PERSISTENT
position changes, and much support. However some wont or can't turn: their
alignment may be just mm out and while both mother and baby have muscle tone the
baby remains "stuck". Surely we have all heard tales from the past of mothers
who slipped into exhausted sleep in such labours, woke up and pushed out their
baby. I don't know the statistics of morbidity/mortality of mother and baby
in such births but can't imagine they are that good as we all know the risks of
PPH, infection, etc.. in exhausted mothers and babies. This is why we have to
watch and listen very carefully in such situations. Perhaps this is why we don't
do this is busy hospital situations where 1:1 care cannot be guaranteed. Perhaps
why such births have more successful outcomes in a homebirth/birthcentre
environment where 1:1 care is guaranteed.
I do wonder about the effectiveness of the so
called "walking epidural" in such slow/stalled labours. Where I practised
homebirth in Seattle the slowly progressing, exhausting labour was the most
frequent reason for hospital transfer and for most of these women an effective
epidural and sometimes (but not always) a 'whiff' of syntocinon was all that was
needed for the baby to descend and birth. We did have one baby that never
descended past the pelvic brim and mum went to 41+ weeks then SROM, days of
early painful labour (with antibiotics and careful monitoring), finally an
epidural that never really worked (started with the walking epidural) and
finally a c/s: baby was direct OP, only 3300g, mum was extremly fit and active.
Another young woman's waters broke at work and she progressed (galloped) to
fully dilated in 2 hours, we rushed to her home but finally transferred to the
hospital after 2.5 hours of pushing and no descent. This mum refused an epidural
or any pain relief, did receive synto for an hour or so, then agreed to a c/s
rather than a mid-forceps: baby was too high for a vacumm. This mum again very
fit, soccer player, baby just 2800g, persistent direct OP.
I do think that often either SROM/ARM are
responsible for these babies getting "stuck", which is why I try to
preserve membranes (ie I avoid ARM) especially if labour is sluggish. But often
with OP babies the labour starts with a gush! WE often decry the "modern
lifestyle" and the couch potato syndrome as reasons for the prevalence of this
unfavourable position in babies. I must confess i have seen this more often in
the very fit mother, primip, often an athlete, very firm abs. That I have
also seen it in considerably less toned multips leads me to suspect it may be
largely due to the internal shape of the maternal pelvis, which also leads me to
believe that it is quite a normal presentation for many women and that with time
and good management and support the baby will birth. What I have also observed
(and experienced personally) is that our bodies learn, I truly believe our
muscles remember, and unless mismanaged from outside, subsequent births will be
easier: those deep internal muscles remeber what to do to give the baby a
"passageway" and not an obstacle course to be born.
I can only think that the 1cm/hour rule is there to
avoid obstetric disasters, we can only replace it with true midwifery
care.
in respect

ps: I think walking epidurals are truly effective
pain relief for the woman with a normally progressing labour, that is she would
have the baby in a couple of hours of active labour with or without the
epidural. I just don't think they are an effective "treatment" for stalled or
potentially obstructed labours. I don't think there is any research on
this.
