Whenever I am on the ambulance, I make sure to check the fridge for a "Vial Of Life" and check the patient for tattoos on the wrists or arms, which in the unconscious patient can serve as part of your SAMPLE assessment. Moreover, patients are now being advised by their physicians and pharmacists to carry a list of all medications they are taking in their bag and to keep one copy on the fridge for EMS. Any of you who have worked EMS will know what a job it is trying to find out what a patient is taking when they are drifting in and out of consciousness.
