I just got done with 2 weeks of neurosurgery, we had or everyday except wednesdays(clinic day in afternoon),usually scrubbing in to do some minor things on one case a day and then we came in one of the weekend days for rounds and anything going on. No "theater". I didn't have that much time to do outside studying, days were like 5-5, one or two that went later, a couple shorter.
I felt like most important things were daily presentations on rounds and knowing your patients in and out, thats the main thing we're evaluated on, and some other talk. Knowing all the labs, vitals, acute changes, fluids coming in and out was important esp. for ICU patients and knowing what orders are going in and have gotten done, what needs to get done that day. Actually examining the patients is usually really quick, just check how well their extremities work and how alert they are. Imaging is how the attendings tend to make all their decisions. Try not to present a radiology read if they havent agreed with it, ask the resident what the read is or remember what they say it is if you have radiology rounds prior to patient rounds.
