Help on ER procedures

[kengr]

For yet another story (I'm working on a large backlog of ideas), I need some info on how things would go at an ER after the parents bring in a young teen with some rather unusual injuries.

I'll have to modify stuff some, since it's set in a universe that has mutants, superheroes, etc. But I want to have some idea of what happens in reality before I try working out how things will deviate from our reality.

The injury involves detached body parts btw.
