I'm an anaesthetic practitioner and work in theatres where we do emergency and elective caesarean sections.
If you come to theatre because you are not progressing in labour then a spinal will be your first line of analgesia. This is a very quick/pain free injection in the back and believe me you will thank your anaesthetist after! They become your best friend once you cant feel those contractions anymore!
A GA will not be offered to you as maternal request. It puts baby at risk and also takes mum longer to recover. Not to mention both you and your partner missing out on an amazing experience!
Of course spinals and epidurals come with their risks which the anaesthetist will explain to you beforehand but these risks are so small and is just something they have to warn you of.
I have worked in theatre nearly 10 years at it is so rare to see complications from epidural and spinals. 99% of the time they work beautifully and once you have that baby in your arms you won't be worried about how they arrived and whether it was on your birth plan or not.
I'm the complete opposite and am pro epidural! I feel like I would benefit not only from the pain by having one in, but if something does happen and I am whisked to theatre as a crash caesarean then I have more chance of being awake and experiencing the birth as my epidural can be topped up (sometimes the obstetricians don't allow the anaethetist to put in a spinal as they want the baby out asap) rather than having a GA.
I know needles are scary but local anaesthetic is used and all you will feel if pushing/pressure (just like when ypu have treatment at the dentist) and nothing sharp in your back.
I hope this has helped. Good luck with whatever you chose at the time!
