I agree with foraneman, MoLee228 and Tinabeanrn. I like ICU when I have the sickest, most unstable patient because I like to be busy and particularly like a challenge. I do find patient care and and the every day tasks (q1h vitals and I/O's, etc...) mundane. CRNA is completely different than most of the the work you do in an ICU except if something goes wrong you are responsible for the decision making. Not to mention after the pre-op and post-op follow-ups, you likely won't have an ongoing relationship with the patient.
