I've lurked through the previous thread and wanted to share my two cents.
For me, having an epidural wasn't about ideology, and wasn't a decision made at a panicked moment in transition when I 'just wanted the baby out'.
I made an informed decision - I wasn't mobile anyway because of constant fetal monitoring, and after two membrane sweeps and having my waters broken, my labour was progressing pitifully slowly.
I was managing the pain well through gas and air, but considered how I would cope if the pain a) continued for another 10 hours (which it did) or b) got worst for another few hours - I decided that an epidural was the best thing.
For me, remaining lucid and coherent was the most important thing. There were lots of decisions being made about how to proceed and I could see that if I wasn't aware enough to make them, DP wouldn't know enough, and the consultants would just forge ahead. At one point the decision was whether to do a fetal blood sample, or start preparing for EMCS, and without the epidural I don't think I'd have been able to sit and have a proper conversation about that.
In summary - for me, the epidural was about making the best of a relatively complicated birth, and making sure that I remained in the driving seat. Luckily the consultants and midwives were pro epidural in my case, and I still feel it was the right decision.
My point is that if doesn't have to be an ideological decision, or something you scream for when you're panicking. I made a pretty calculated decision, and it worked for me. I'd like to see more consultants have an early conversation with women giving birth, so that they can think about pain relief while they AREN'T panicking, and make a decision that is more informed.
