Wow ! I saw one yesterday. It was incredible. I had no idea how interesting or complex it would be. There were at least 10 people in the room as it was a teaching hospital. There was a CT surgeon, a CT fellow, an gas man and a gas resident, a profusionist and a profusionist in training, several scrub nurses and two guys handing the docs tools ( some kind of med techs ). It was an incredible experience. Next, I want to see a neurosurgery !
