I don't think you're putting a fine enough point on it, Mustafa. In all of these examples, there is a
clear correlation to immediate treatment equaling better prognosis - benefit/risk ratio is clearly in treatment's favor (i.e., you can't leave the victim in the car, non-treatment of a tension pneumo results in rapid death, etc.) Myocardial tissue can be hypoperfused for four to six hours and still recover. Likewise, so many people report chest pains (that turn out to be MI) way too late anyway and thrombolytics don't do them any good. Besides, you can't do CK-MB and troponin levels in the field, and many ER docs won't give thrombolytics until they have a clear cut diagnosis.
Also, I remember a study that was quoted (and I'm trying to find it) where they showed doing 12-leads in the field was an abyssmal failure in one EMS (I think it was Seattle's) system. Distinguishing between an old infarct and a fresh one can be tricky, even for cardiologists, sometimes.
And, what about the legal liablility? What happens if you exsanguinate someone in the field because you gave them thrombolytics when what they really had a GI ulcer with equivocal ECG findings... all when the hospital was only 20 minutes away anyway?
I think those are the real issues here. Of course, we all want the best, fastest, and most effective treatment for all patients. No one is arguing that.
