Abstract
  High quality care balanced with cost is required in ambulatory surgery. Side effects, such as postoperative pain, nausea and vomiting, dizziness, drowsiness and urinary retention, not only reduce patient satisfaction but also prolong the hospital stay and increase cost. It is not recommended to use techniques and agents that cause side effects and result in delayed discharge, as well as consume expensive drugs and resources without limitation. Postoperative pain, nausea and vomiting should be prevented and treated because these are the most important reasons for prolonged stay after ambulatory surgery. Multimodal balanced analgesia using local and/or regional anesthesia and other non-opioid analgesia provides superior analgesia with few side effects. Careful patient evaluation and selection, and education for patients and providers are essential for a successful outcome.
