Wow, an asethesiologist? I guess you were really out. Also a way to jack up the price.
I had a nurse give me an IV... Valium and something else. I wouldn't have had the colonoscopy if I had been under a general anesthetic, which scares me to death. I've only had one surgery (emergency) where I've had to have that and if I have any say, it will never happen again. I know 3 people who died from anesthetic.
