Post-operative nausea and vomiting

摘要

Post-operative nausea and vomiting(PONV)is a common complication of surgery and anaesthesia.Although it is rarely fatal,PONV is unpleasant and associated with patient discomfort,and dissatisfaction with their peri-operative care.Patients have reported that avoidance of PONV is of greater concern than avoiding post-operative pain.PONV is also associated with delayed discharge from the recovery room and prolonged hospital care and,therefore,increases health care costs.
