Sorry to bump an oldish thread, but I wanted to chime in that a closed MICU rotation will likely be much more helpful to you than a typical, open SICU rotation during your intern year. SICU often has a level of complexity and requires a degree of collaboration that you just don't have the tools to effectively deal with when you're still learning the ropes. At this point in your training, I think it's more beneficial to be in a closed structure where the typical anal, academic pulm/cc attending (who, in my experience, disdains all his medicine colleagues on the floor who consult for everything) is going to force you to think about all the minutiae of your patient's comorbidities and the subsequent interventions you need to undertake to fix them. They have time to do this kind of mental masturbation during their interminable rounds because the prone ARDS patient likely isn't going anywhere anytime soon... unlike the SICU patient who might be scheduled for his 4th OR bringback that morning. More often than not, you're going to get a better foundation in EBM in the MICU because a lot of those folks constantly review the latest articles on ventilation strategies, sepsis/appropriate antibiotic use, pressors, glucose management etc. Don't get me wrong, you're definitely going to pick up some tidbits during SICU that will help you when you start doing anesthesia in earnest, but right now it's more important for you (and your future test scores) to focus on things like blood gas interpretation, cardio/pulm/renal phys, sedation pharmacology, and vent weaning strategies rather than worrying about the difference between a type I or II endoleak or whether triple H is really that effective for vasospasm.
Also, as an aside, you should be doing/volunteer for every a-line, central line, peripheral IV, intubation and LP you can get your hands on. And play with the ultrasound frequently as well, not just when dropping in an IJ. Having some decent degree of preexisting hand-eye coordination will make your life easier when you start in the OR, and also make you look like a rockstar to boot when your attending doesn't have to sit there watching you struggle when he's got another case to start in his other room.
