Continued advances in procedural techniques, anesthetic pharmacology, and regional anesthesia allow more prolonged diagnostic and therapeutic interventions to be conducted at an increasing variety of locations outside of the operating room (OOOR). However, recovery and discharge process may vary according to the patient’s condition and the specifics of the procedure. Generally, most patients are sent to the postanesthesia care unit (PACU) and ambulatory surgery unit (ASU) or a medical post-procedure recovery unit not staffed by an anesthesiologist, while some patients receive special postoperative care in a step-down or intensive care unit. Therefore, ensuring rapid postoperative recovery and safe discharge are important components following these OOOR procedures.
