Hi Jill - Vinny is correct....I had my surgery last week at the hospital of special surgery with spinal. Initially was very scared but didn't really have a choice as this is their protocol. My sis, who is a doctor, told me they will never "promise" you that you won't hear anything...but if you tell them your concerns (and I was very blunt) they will make sure you have a heavy sedation. I made the anesthesiologist promise me that he would constantly watch me to make sure I wouldn't wake up. It sounds funny to me now but I was deadly serious. He told me he had no place else to go during the surgery and that both eyes would be glued on me. Also, I didn't want to see the operating room - so he gave me a "cocktail" before wheeling me in. I don't remember a thing until waking up in the recovery room....
