Gentle,
I am simply commenting based on the observations and experiences I had at the OMS programs I visited in the AF.
The time spent in the hospital and on call all depends on what rotation you are on. Generally, the hardest and most demanding rotation is consistently the OMS rotation. Residents seemed to arrive anywhere between 0430 hrs to 0600 hrs to do pre-rounds, paperwork, study etc. After the work day finishes around 1630, residents must round, study, do lab work, paperwork, set up case presentations etc. They leave anywhere between 1930-0100hrs. Generally, earlier in the week the residents left a little earlier and as the week went on they stayed later and later each night until Thursday night when they sometimes sleep over, don't sleep or go home super late and come back at 0400. This is because Fridays are dedicated to case presentations that the residents present along with a day full of being grilled about the various cases that were seen that week. And, of course, if you are on call during these you take call and may not sleep at all during the week
. My friend who just finished at Lackland said one week during his first year he slept a total of 3 hours one week due to nonstop call.
Anesthesia is regarded as one of the easier rotations when some residents have been let off at early afternoon. I didn't get to see the other rotations, so I can't comment on them.
Hope that gives you a general idea of the type of schedule the residents have.
Ohh and just have your wife prepare to be a single mom for 4 years, because you won't be much help at all. She has to be as dedicated as you are to being an Oral surgeon for it to work out.
