AbstractPost operative nausea and vomiting (PONV) remains an unpleasant and persistent problem for patients undergoing surgery. In fact PONV are among the most important factors contributing to delay in discharge of patients and an increase in unanticipated admissions after ambulatory surgery. Anesthesia providers are most often blamed for PONV, sometimes rightfully so, many times wrongly so. PONV is a multifactorial issue involving many physiological and biological mechanisms. As the trend towards ambulatory surgery increases, PONV continues to pose serious challenges for anesthesia providers because the potential cost savings of performing surgeries on an ambulatory basis may be negated by unanticipated hospital admission. Although PONV may be unavoidable in some patients for reasons we do not fully understand, there are risk factors that can be identified. As anesthesiologists it is essential for us to understand the mechanisms involved in nausea and vomiting and the available perioperative treatment options. We must do whatever we can to prevent and treat PONV and improve patient outcome for both medical and economic reasons.
