A U.S. News & World Report Best Ambulatory Surgery Center!
Our center has been named one of the Best Ambulatory Surgery Centers in the nation by U.S. News & World Report.
My visit was for the purpose of a colonoscopy screening. After checking in but before the procedure I was presented with a variety of forms to sign and date, some of which referred to the type of anesthesia the doctor would use. I was introduced to a member of the staff, perhaps the anesthesiologist, who went by the name of Camille. She explained that I would probably be given a light "twilight" anesthetic. But when I awoke from the procedure my discharge paperwork stated "deep sedation provided by certified nurse anesthesia provider." While the information as to what anesthesia I received was disclosed to me in writing post-op I was hardly in a position to read or question the staff about it after having just woken up from the procedure. My intent is to determine why I was given deep instead of light sedation. Any information you can provide is greatly appreciated. Thanks
