I anticipate a lot of EMS agencies going on line with pre-hospital, post arrest hypothermia soon. It's good to look at that in the light of some other EMS interventions that may be falling into disfavor.
In other words, we may quit doing procedures on certain penetrating trauma patients, we may quit intubating as frequently as we do now, and we will face other changes. But everyone needs to understand that the same science that forces us to "lose" these things (if you look at changing practice due to scientific advances as a "loss") will bring new therapies on line to satisfiy everyone's desire to help their patients.
