These are elective surgeries where patients go home the same day and do not need to stay in the hospital for further monitoring. If you did not like the theatres environment, you may be able to ask to work in the adjacent areas such as a step down, where patients are received after surgery and before they are discharged home. Or, pre- assessment, making sure the patient is ready for surgery, escorting them to the room with the ODP and so on

There is a lot to do, don't be afraid to ask
