Pre-op/PACU in a ambulatory surgery center(ASC) would be very different from the same in an acute hospital. The patient's are generally healthy or low to moderate risk in ASC. Early on in your career you might be better off in the surgical icu. If you worked at the surgery center for a year or so and lost your job or wanted to leave it might be harder to get back into the acute setting.
I work acute care medical and part time at an ASC. They are worlds apart. I feel challenged every day at the hospital not so much at the ASC. However my long term plan is to retire from the acute care in 10 years but continue to work at the ASC.
Every ASC is different but there is a lot of orthopedics , ENT, eyes, podiatry, some plastics, pain injections, some general surgery and sometimes endo/colonscopy.
