Had an epidural with ds, hadn't 'wanted' one, in fact it had been thought it wouldn't work because I have scoliosis, but I was having a hard time and we were going into the third day of contractions with very, very slow dilation so the MW asked if I'd like to try one. She was brilliant, the anaesthetist was brilliant, it worked a treat, possibly slowed down contractions and contributed to needing ventouse but almost certainly speeded dilation due to me being more relaxed. No suggestion of me being denied it. It's a hideous thought that someone in my position but unable to pay might have to go through that (including the very protracted stitching of the episiotomy afterwards) without. A friend of mine who also had one for her birth said it had made her feel human again within minutes. That's the effect it had on me too.
This was in Germany. I had crap bf advice afterwards on the ward, but the birth - despite being difficult by anyone's measure - was so much more bearable due to the wonderful, supportive, professional people I had around me. I read some MNers' birth stories and feel, tbh, very grateful I was over here for the birth.
How would they define 'definite need' of an epidural? The potential for abuses and power trips is enormous.
