From what I've read, and what other posters on SDN indicate, the 80 hours thing for surgery, while not enforced to the letter, is a good ball park. Probably closer to 90, and maybe a few more as an intern- you can't run a service of 35 patients without doing the work. A word of caution though to the OP- if there was a magical field which combined stimulating scientific/clinical variety, low stress/manageable hours, and solid pay you'd bet I'd be gunning for it. I don't think IM specialties are doomed to failure as someone pointed out- but the way compensations are going, they are certainly doomed for monotonous, bad medicine. I shadowed a private practice GI doc, who told me 1/3 to 1/2 of his appointments are for IBS (irritable bowel)... but his bread and butter are colo's and EGD's because a half hour procedure banks big cash- translation is you scope the hell out of everyone. Boring, probably not entirely ethical, but certain lucrative and good hours. Similar for cath- a NY times article earlier this year talked about a private practice outside Cleveland that had 4x the national average of doing caths. Academics, while it has its pitfalls, might be a better option to get what you're looking for. Just a thought.
