Postoperative nausea and vomiting (PONV) is considered to be the most unpleasant experience associated with surgery and is believed to be one of the most common reasons for poor patient satisfaction in the postoperative period. It also results in prolonged hospitalization and increased use of resources such as intravenous fluids and drug supplements along with prolonged medical attention, all of which have psychological and financial implications. In addition to this, PONV can result in aspiration, laryngospasm, dehydration, electrolyte disturbances, gastric bleeding, increased intracranial pressure, increased intraocular pressure, and wound dehiscence particularly when the surgical intervention is performed through an intraoral approach. It is a well-known fact that there are many etiological factors as well as predisposing factors for PONV. Hence, this review is intended to evaluate as an individual factor what the role was played by the anesthetic agents used for GA in the incidence of PONV.
