I didn't have an epidural with DC1, as I felt I had enough risk factors already for an assisted birth without one. Luckily labour progressed normally, and I managed without one.
DC2 was a whole other ball game. While I was much more mobile, and overall more tolerant of the pain, progress was sloooooow. In the 10 hours I'd been hooked up to the drip, I'd progressed from 2 to a measly 5cm. For context, in the same amount of time, I'd dilated to 9cm (from 1) with DC1. Baby was back to back as well, so I knew opioids (my preferred choice) would likely wear off long before full dilation, landing me back at square one. Gas+air was no longer sufficient, and the pain was intolerable, so epidural it was!
I had to wait 90 minutes for the anaesthetist. Not bad for a Friday night handover request. Though contractions continued even though the drip was turned off.
Once the anaesthetist arrived, they checked I definitely wanted the epidural, and went through the risks of the procedure. They got me into position (sat on the edge of the bed, feet on a chair, hunched over a pillow to help open the spaces between vertebrae). My back was sprayed with chlorhexidine (so COLD!) to sterilise it. Local anaesthetic was injected (stings and burns for a moment, but quickly goes numb), then the epidural needle was inserted. I won't lie, I could feel the needle. It wasn't quite sharp, but it was more than the pushing feeling I was led to believe. I was desperate for respite from contractions, so I told the anaesthetist I could tolerate it and to continue, which she did. It all went well, no nerves were touched by the needle causing any electric shock sensation. I got the cold wave, which felt wonderful, and contraction pain lessened immediately, but didn't quite disappear. They didn't disappear completely until after a few boluses from hitting the top up button. I could still feel and move my legs which was unexpected. I never got the opportunity to see if I could stand or even walk, though I think I could have.
Unfortunately I didn't go on to have a vaginal delivery. Baby was stuck and starting to show signs of distress, so I had a C-section. Having the epidural in-situ was nice, as it just needed to be topped up. Needed quite a hefty amount of top up too, as I could still feel the cold spray when I shouldn't. Once the C-section was over, I was out of theatre by 3am, had most of the feeling back in my legs by 5am, and could stand and take a couple of steps by 7am. Full sensation back by maybe 8.30am.
Best of luck with everything.
