Tracy, excellent thread I discuss this with my students all the time. Although trauma is a " glory " call anyone can be proficient immobilize, oxygen, maintain airway, lung sounds and a blood pressure and transport to a trauma surgeon.
For a medical call you have to " diagnose " the complaint and then treat the illness appropriately, and transport to the hospital that will provide the patient with the best service ( not all of our receiving hospitals are stroke centers or have cath labs ).
I understand the challenge of medical calls for the medics in the crowd. You have a multitude of diagnostic toys to play with, and a much wider variety of treatment modalities than a BLS provider who has but O2, ASA, EpiPen, Nitro, AED, reassurance and transport.
I find we in the BLS world get to stretch more when dealing with trauma if it's other than our typical OPFDGB "old-person-fall-down-go-boom" call, or a just plug the leak, scoop and run call like they do in the "big city". Outside of the city there is a multitude of messes people get themselves into that all present their own special challenges. How are we going to gain access, package and prep for transport, disentangle, etc? And for each phase of the call there are different tricks and tools to be used.
So I come down firmly in the Trauma Junkie camp.
If we get a medical I do the ABC's, assess, make the patient comfortable and make sure they already called the guys with the drug boxes. Dave C.
