I am so sorry for you having to go through this. I have worked with first responders/military/public safety for a long time and there are many people who exhibit these types of characteristics. I had a colleague that used to call them adrenaline junkies, glory hounds or maybe stress addicts (which I think I may be.) Not really sure if there is a great way to handle someone who is amped up on the fight or flight rush, sometimes they can even be good, though probably not in a hospital environment. Best advice I can give is to be the utility player, plug the gaps that others create when they are not thinking clearly, and be the voice of reason if they are making mistakes. DON'T be pushed around if you are right, but don't look for conflict just because they are being aggressive either. Docs and more experiences personnel will notice how calm and cool you are under pressure with others flopping all over the place.
