Office-based anesthesia has given rise to the demand for S.A.F.E. (short acting, fast emerging) anesthesia. This need is greater in the office setting than in either a hospital or a surgicenter since it is paramount that patients in an office-based setting recover quickly-pain and nausea free-in order to free up the operating room, which often also serves as the admitting, surgery, and recovery room. Patients awaiting a procedure, or the physician scheduled to conduct a patient consult, can be delayed if the surgical patient is unable to emerge quickly from the anesthetic.
