Firstly, thanks for highlighting the risks associated with epidurals OP and neef - I am so sorry to hear about your experiences and I wish you a good recovery. I will certainly think v carefully if an epidural looks to be on the cards for me and after reading your post neef, I think I will mention in my birth plan that I would not like anyone to offer me an epi.
Re the OP - thanks for mentioning possible problems following instrumental deliveries. However, it seems to me that instrumental deliveries can be life saving procedures. I know that if I had the option to have a forceps / ventouse delivery vs risking life threatening injury to my baby or me, I would pick forceps every time despite the risks, (which btw I was aware of before coming across your post, although maybe not in such detail).
The OP reads to me as if mums should be warned off assisted deliveries full stop and does not mention epidurals at all, which I don't really find particularly helpful TBH. Unless every woman in the country is to have an ELCS I don't see that the use of ventouse / forceps in some cases can realistically be avoided..? Maybe someone can tell me differently.
