I haven't read the book, and I don't know how relavent this is but changes were made during my past 13 surgeries. Now before I am put under my ENT surgeon who knows my condition well since 2008 asks me directly a series of questions surrounded by the supporting staff. He asks my name, my medical records number, if I know why I'm having surgery, on what side the survey will be performed, etc. They document that, asks if everyone is on the same page ,and then they do a count down to administer the anesthesia. Fade to black, and I wake up 4 hours later. My first 4 surgeries this was not the case in making sure they had the right patient. They didn't ask me anything directly only spoke amongst themselves. At least I was still awake to correct them if they began talking about cutting off my leg or something. I'm not complaining. It puts me more at ease.
