I'm pretty ambivalent about epidurals, although obviously I think everyone has a right to ask for one if they really need one. I wish there were better, FREE, education about what labour might entail and what you can do to cope with it though, because I think some people have epidurals out of panic. I did, I think.
I had an epidural with DS - I was induced, and although I think it was quite a benign induction experience, I got to the point where I started to wonder if I could cope much longer, and the MW then said she thought DS had turned back-to-back (I don't know if this was the case).
First thing I did once it was in, was lie down and sleep for an hour! I stopped being active and sitting on my ball. I could have continued to do so - the MW was very supportive and in fact I could just about walk, so I think I could have sat up. So while I have no idea if the drugs themselves slowed things down (I suspect epidurals don't do this), my behaviour and expectations and motivation certainly changed.
I went from being very motivated to stay upright, partly because the pains were 'telling' me to do stuff, to being virtually a spectator at DS's birth. I felt very detached and only really came to when he landed on my chest. There were some decelerations that had the MW worried, but by then I was dozing and just presumed everything would be ok. I have no way of knowing if this was down to the epidural (my attitude, not the decelerations) but I suspect that after being very tired and in pain, I'd had that taken away from me and had sort of given up my autonomy to the HCPs. They'd taken away the pain - they could also do all the worrying, telling me when to push, etc.
I had two top-ups and had to push while completely numb. I couldn't feel anything more than pressure, although the obs (yes, I had one of those by then too) and the MW and DH were being very cheerleader-y and telling me when to push, etc. DS was born after an episiotomy and ventouse (although I still think he didn't need that, as he virtually shot out).
So on one side, I think epidurals are great, in the right context - I mean, I gave birth pain-free, DS was absolutely fine (apgar of 10 at birth), and my episiotomy worked out ok in the long run. (It might not have, though.) But I felt totally divorced from what was going on, until DS was born. Nobody pressurised me to have it, BUT I think I'd set myself up for having one because I was induced (for high BP - epidurals are at least a good way of lowering that!) and I'd told myself I would probably need one because an artificially started labour would be more painful than I could cope with. I don't know if it was my NCT classes that made me think like that, or just my natural catastrophising!
Next time I have a baby, I'm ideally going to be labouring at home, with an Independent Midwife and not using pain relief aside from G&A (which I had earlier on and got on well with). I won't opt for an epidural unless I really need one, rather than feeling intimidated by what was to come, rather than what was happening at that point.
Sorry, I rambled on for ages.
