Hi
I had surgery recently on my shoulder.
They knocked me out for it.
I'm a funny onion MDI and do it all myself with no specialist or DSN.
The hospital had a Pharmacist phone to give me advice (!) on what insulin to give!
He was about 12 but as luck would have it he advised me to reduce my insulin on the day which i was going to do anyway.
On the day the anaesthetist was happy me being in the 7s with nothing on board only background insulin.
She seemed more concerned with the injection which she called a blocker and it was the biggest needle i had ever had in me!
The op took about an hour and i came round fine and dandy and my sugar levels hadn't moved.
I wish you well.
Tony
