I feel like I lucked out with my surgery prelim. 7 out of the 12 rotations I'm the only resident on service, so I scrub in a ton of cases and do more than just retract or close skin. They also tailored my year to be a bit more relevant to anesthesia. I got 2 months of SICU, but the hours are pretty protected (8a-6p, M-F, alternating weekends, no call/overnight). And that was in lieu of some of the busier, service heavy rotations that the categoricals take.
I've done chest tubes, a-lines, central lines, excised skin cancers and cysts in clinic, a decent amount in the OR. And thus far I haven't gone over 70 hrs/wk worked, averaged closer to 55 (although the first half of my schedule were the chiller rotations). There are about 3 service heavy rotations for the year, rest is pretty manageable.
Honestly feels more like a transitional year. Although my program is structured that even the chiefs agree the intern year is relatively chill with above average OR exposure. The only downside has been that I agree with others in this thread regarding teaching. The teaching is there if I ask questions or ask for help, but otherwise I'm kind of left to my own devices.
I would agree overall to avoid surgery years because I think my program is more the exception rather than the rule.
