Several years ago I had a failed intubation that resulted in an infection that was almost fatal. It was suggested that I get a Med Alert tag stating "History of Traumatic Intubation", but I never have. I would be concerned that if I were unconscious that the people treating me know this fact, and therefore I would want the Very Necessary ID card to be found.
I have never really understood the need for this tag. If you need an airway, you need it right now. Knowing you're hard to tube is just going to stress the EMT or ER doc. Ignorance is bliss. I would rather find out you are a difficult airway after I have an ET tube in you. <img src="/images/graemlins/wink.gif" alt="" />
