Hi, CTBarrister. I will ask my surgeon what he used to sedate me. I am almost certain he said Propofol. Perhaps sedation procedures are different in Canada? My surgeon administers the drug into my IV. I know there wasn't an anesthesiologist present because I would have been introduced to him/her. He always introduces his team, resident, nurse, aide, etc., since it would be considered rude to peer inside someone's bum without formal introductions! Then they briefly discuss me while I'm in the room, my name, birthdate, procedure, and then I'm asked to sign something -- just to make sure someone else didn't volunteer to take the scoping for me, and for liability.
Before Covid lockdown, we always set a followup in the office to review my scope and CT scan results. Now I get results by email to save a trip to the hospital.
