I love medicine. It's the reason I am doing a CCM fellowship. I came into anesthesiology always wanting to do CCM. Anesthesia is truly medicine in action. ICU is medicine in action. Sure we miss the long term management of things or nitty details of certain disease processes but all in all, we get to actually practice what we learned pharm/physio in medical school nistead of worrying about dispo/most social issues/etc. Having said all that, like a poster said, IM and anesthesia are separate fields unless you only want to do CCM. Really think if you'd be willing to do clinic vs OR. I sometimes think that I regretted not doing the IM/Anes 5 yr track but I just didn't see myself doing IM residency after I had finished my prelim medicine year. However, if you pick only Anesthesia residency route, please keep brushing up on your general medical knowledge because it's so easy to fall into that trap of just get the patient through the surgery (Prop/roc/tube mentality). Also, do a prelim medicine year with plenty of MICU if you're so inclined. There are also combined Anesthesia/CCM programs which if you don't mind staying at one place is actually good since you can have more ICU time and elective time through your residency. I honestly donn't know much about those but it sounds good.
