Ors,

It might not be a bad idea, although if you need an airway most paramedics etc would try and secure your airway prior to checking a medical alert braclet. I have never seen a medical alert braclet with "history of tramatic intubation" or anything similar.

Yes, paramedics and EMTs who have intubation in their scope of practice typically have other options to secure an airway. Here, we call those options "rescue airways" and range from blind definitive (and a few non-definitive) airways to surgical airways. There are pluses and minues to both, and in my opnion neither are as good of an airway as a properly placed, proper sized oral intubation.

While they look brutal and barbaric to the untrained, a field surgical airway is an excelent rescue airway that when done properly merely leaves a same scar and only slightly increases recovery time... Which is much, much better than no airway!
