I had my baby boy on Monday. I have had had a fear of needles all of my life, and had over the course of my pregnancy learned and worried about the "cascade of intervention". So I was insistent at the outset that I wouldn't have an epidural.
I ended up being induced with syntocinon because of meconium in the amniotic fluid, but after 12 hours I was only 3cm dilated and in huge and unexpected amounts of pain. During the last hour I used gas and air, and found that it made me feel completely out of it and I felt as though I had lost control of the contractions - my mind was too fuddled to let me prepare for them. I ended up demanding an epidural "now now now" and was lucky enough that the anaesthetist was able to administer one after around 30 mins.
I regained control and felt better - physically and mentally - almost straight away. My husband was also hugely relieved by the transformation - that I was back and able to make decisions with him again. Physically I could still feel contractions but as pressure rather than pain (although there was still some pain lower down but it was manageable). I could still move my legs, although it wasn't technically a mobile epidural. My movement was limited anyway because of the syntocinon drip and because I was hooked up to the foetal heart and contraction monitors so this wasn't such an issue.
Over the next 5 hours I progressed to 8cm dilated and I don't think this would have happened had I not had the epidural - I was in such a panic when in pain that I feel that I would have gone backwards without the epidural.
As I came to push, the epidural was wearing off on one side and so I asked for a manual top up. This took away the pain and did, admittedly, make it more difficult to know when to push, but the doctors and midwives were able to tell me when my contractions were coming. Again, the fact that I was together and in control at this point was crucial for me and made it possible for me to listen to the medical team and follow their instructions. The pushing phase lasted around 40 minutes so I don't think that the epidural impeded progress at all.
Having started out insistent that epidurals were A Bad Thing, I feel very strongly now that they have their place if the circumstances call for them. It was purely a positive experience for me and whilst I would try to labour without one if I have another baby, I will be much less scared and much more open minded about them.
