Abstract: Pediatric ambulatory surgery can minimize the separation of pediatric patients from their parents, relieve anxiety, and offer care at a reduced cost. However, children are prone to experiencing pain, nausea, vomiting, delirium, and other complications after anesthesia and ambulatory surgery due to their anatomical and physiological characteristics. So, standardized postoperative management is critical to ensure the safety of children and improve the medical quality of pediatric ambulatory surgery. This article reviews new progress in research on common postoperative complications and discharge criteria of pediatric ambulatory surgery.
