I had a minor gynae op a few weeks ago in a private hospital.
It all went very well, but although I had great care, I have to say that the opportunities for asking the consultant questions were quite limited. The nurse who came in before and after my op was fab, and made it clear that she had time for me, but while the consultant was lovely too he was much more 'ok, blah blah blah, you take care now, see you in a few months'.
I think the consultants time is v precious, that's how I understand it anyway. Luckily I had lots of leaflets explaining my procedure before the op, and am very proactive at researching stuff on here etc, so I knew the score, but it would have been confusing for me without this prior knowlege.
Btw I'm sure somebody has already said this, but they won't give you a time for your op. This is becuase they won't know until the day, and even then 'events in theatre' may change the running order.
It is horrible having to lie there gasping for your breakfast and a cuppa, but it doesn't last too long, and you can eat afterwards. Also you can usually use your mobile so don't worry that your DH won't know when to collect you.
I thoroughly enjoyed my very first general anaesthetic (yes, I'm weird) and found the whole experience much less stressful than the idea of it. Good luck.
