anesthesia
"Was given propofol for my recent colonoscopy & I can't say enough good things about this drug.  This was my first colonoscopy & the Doctor initially wanted to use conscience sedation but upon reading all the reviews I insisted that he use propofol.  I'm glad I did.  The only pain I had from the entire procedure was when the put the IV in my hand (which really wasn't that bad), other than that everything was a breeze.  No pain at all when the injected the propofol into my IV.  After they put it in I remember feeling a little warm sensation in my body & the machines in the room I was looking at starting to get a little dark then they were waking me up saying I was all done. :)  The propofol wore off quickly & I walked out in under 20 mins."
