I'm a plastics RN in Missouri (in my spare time -- the "day job" is neurosurgery). i have worked in a private plastic surgery office for almost 4 years.
I see patients in clinic. The clinic examination is different from the head to toe that you do at the hospital, but pretty straightforward, once you get the hang of it. Physical examination will probably be a focused one (ie skin, hand, abdomen, breast). I am expected to write/dictate clinic notes, insurance letters, etc in a timely manner after the visit.
My OR duties include circulating, scrubbing, and administering conscious sedation. This is the learning curve for most nurses, because this is not taught in nursing school, and the wards/units don't give you ANY perioperative experience.
I do aesthetician procedures, if I'm free, like laser txs, chemical peels, microdermabrasion, etc.
I think the best preparation is OR or clinical experience, not floor or ICU experience. It's a whole different set of skills involved. Yes, you "recover" patients from conscious sedation, but that is far different from general anesthesia. If you are in a surgery requiring general, you will be at a facility that is staffed to recover patients.
Salary: less than my salary at the hospital. Hours: 0730-1700ish, entirely dependent upon how many patients we have. Holidays/weekends: generally no, but we will accommodate almost anything that the patient is willing to pay for.
