I did a couple of weeks work experience in the cardio surgery at Kings College Hospital when I was about 16-17. Probably something that no-one in their right mind would consider authorising nowadays!
Was quite eye-opening and also very entertaining. They had CCTV between the theatres so surgeons could ask advice, check up on other operations etc but they mainly used it for discussing their next foreign holiday or the size of the loft extension that was being fitted to their 5-bedroom detached house. While operating.
"Yeah so the builders are a right bunch of bastards - scalpel! - trying to rip us off and saying the job - forceps! - would take three months and we were like - nurse, hold that bit there - three months, but we go to the Bahamas in 2, you'd best be finished by then - 2cc of adrenaline - so we'll see."
Meanwhile the patient would be lying their with the chest wide open... It was a good job none of them got to hear some of the things that were said. I did ask once if he'd ever had anyone die on the operating table and he quite casually said "oh, yeah, couple a week usually".
But don't worry, you'll be fine. Probably.
