Ors, why not do what was recommended to you. Get a MedicAlert neck tag or bracelet for your Hx. of Traumatic Intubation. You don't need to go through THAT again!

As for the Medical History card, I still feel that in an emergency it is NOT likely that paramedics will search your wallet. That being said, any good physician one is using (i.e., someone who has your records) would be glad to write down the elements of your history that he/she feels are critical to emergency care. Most probably this will relate to alergies, stents, implanted devices, and perhaps other medical conditions. Don't inflate the list by guessing what is really important to an emergency care provider... ask your doctor. Then, why not type/write it on rite-in-the-rain paper and laminate it in a wallet size RED BORDERED card. I personally would absolutely not use the "service" offered in the link to create a card. I see no need for it, and I see potential risks in it.
