Ushy - as a group low risk mothers who have their babies at home, or who have their babies in birth centres, where they don't have immediate access to epidural analgesia seem to have better psychological outcomes following childbirth than low risk mothers delivering in consultant led units with epidurals available 24 hours. How do you account for this, if easy access to epidural analgesia is crucial for populations of women to increase the likelihood of a happy birth?
"at NCT classes you get told it as absolute indisputable fact!"
Not at my classes you don't! You get told that the relationship is complex and that there is not a clear cause and effect relationship between epidurals and assisted birth. However, I also point out that at present it does seem that there is a very strong association between epidural use and assisted birth in first time mums, and also that the research tends to rely on mothers who've had opioids as the control group, who like mums who've had epidurals, may well spend a great deal of their labour on the bed in a supine position.
I would love to see research comparing outcomes for low risk women having epidurals, when the control group consists of low risk mothers who are encouraged to mobilise, have access to a birth pool, and who one to one care from a midwife experienced in physiological birth. Sadly this research doesn't exist at present as far as I'm aware (though I'm quite happy to be corrected if anyone knows of any!).
"The US anaesthesia professional body"
Personally I have difficulty reconciling American medical opinion about childbirth with what I see here in the UK. Almost all births over there are obstetric led, are induced or accelerated, aggressively monitored, and supine. And really, if that's the case, no wonder women who don't have epidurals often end up seriously traumatised and with poor birth outcomes!
