I DO have a bracelet and a card from my Dr in my wallet. I was advised by my surgeon that I should not have a blind NG tub insertion - you should have a tube insertion with a scope if you need one. I would rather someone know I had the surgery if I am passed out.
Thank you everyone for your responses, great information! Not sure yet what I'm going to do about the bracelet, but for now I will attach something to my insurance card and driver's license.
