Hehe... hope you're not basing your future on a TV show 🙂. I really love ER too though....
I would say that although nothing is quite as frantic as what you'll see on TV, the closest thing you'll get is trauma surgery. The majority of the procedures you see the ER guys do (chest tubes, thoracotmies) are typically done by trauma surgeons. From what I've seen/heard, ER docs don't do too much in the way of surgical procedures, although at some residency programs they do get to assist with tracheotomies and the like.
If you want to get a realistic idea of what truama surgery is like, check out TLC's "Trauma: Life in the ER". Also, they have a new show called "Residents" where they follow around a bunch of residents in different specialties; one of them is a surgeon.
Hope this helps!
