Alimat, I think people forget that midwives are the only people involved in providing intrapartum care who engage with the mother throughout the entire process, from conception through to the postnatal period, in all contexts - from straightforward, normal deliveries, right through to high risk, operative births. Wonder where the idea comes from then that midwives have a uniquely skewed perspective on birth, compared to other health professionals who deal with intrapartum care?
"Some definitions of 'normal childbirth' specifically exclude the use of epidural analgesia (we have lobbied very strongly against this, by the way) but it's not mentioned in the Royal College of Midwives (RCM) definition of normal childbirth which is "?one where a woman commences, continues and completes labour physiologically at term.?
Might have something to do with the fact that epidurals profoundly disrupt the normal hormonal physiology of birth.
And of course that most epidurals involve syntocinon, the use of which is not included in the RCM's definition of 'normal birth'.
"That rider about maternal choice is key to the whole Mumsnet thread, of course, and it is often missed out when midwives quote this maxim."
It's possibly goes without saying because midwives believe it's blindingly obvious that that listening to a mother and respecting her wishes is one of the central tenets of good practice.
"Btw, it's the first time I've seen anyone mention that pethidine has greater and more harmful side effects on a baby than epidurals (pethidine is a sedative narcotic that crosses the placenta, unlike an epidural, and can lead to floppy, unresponsive babies, with all the follow up care/difficulty feeding etc that that can lead to)"
Although interestingly enough, almost all the research which compares the outcomes for epidural births with non-epidural births (and which, as you say, finds minimal disadvantages and risks associated with epidurals) uses as the control group mothers who have had opioids in labour, rather than comparing mothers who've had unmedicated deliveries.
