I love ICU, most days.
My OR experience is limited to one day during school... Circulating might not be bad, but I couldn't stand scrubbing. Literally, couldn't stand
My feet were killing me after about half an hour of standing in one place. Plus, they don't exactly work in shifts, no? I like finishing when my shift is over -- not wait until the work is over. Again I could be wrong about that.
Quite often "ED/trauma" is more like "ED/ran-out-of-meds," or "ED/GI virus" or "ED/I-don't-have-insurance-but-ED-treats-me-anyway." And then there's the issue of the waiting room filling up, while pts are waiting for a bed upstairs.
In the ICU (or in mine, anyway) most days I do care for trauma patients, or else some other variety of critically ill. Most days I am done on time or close to it. Because our pts ARE so critical, we're forced to prioritize actual nursing/medical care over ridiculous luxury hotel expectations (imagine that!)
