As WingedScapula points out, a lot of trauma surg is non-op and ongoing ICU/critical care management. These are 2 things that are discussed in the EmCrit podcasts.
But what the podcasts don't cover is the long term longitudinal care; primarily, once the patient is stabilized what do you do with them for the next two weeks, how do you wean them from the vent, when do you need to go to the OR for washouts or closure, etc, etc. So the podcasts are good, but recognize their limitations. There aren't any easily digestible books that come to mind which cover the long term ICU management of the not-really-unstable-but-just-needs-lots-of-water-and-sunlight patient. That just comes with practice. And as a medical students nobody's going to expect you to know when a patient is ready to go for fascial closure, or downgrade to the stepdown unit.
