Post-Operative Nausea and Vomiting (PONV) is the wonder of queasiness, regurgitating or heaving experienced by a patient in the Post Anesthesia Care Unit (PACU) or 24-hours following a surgery. It is an upsetting intricacy that impacts about 10% of the populace experiencing general anesthesia every year.

Emetogenic tranquilizes generally utilized in anesthesia incorporate nitrous oxide, physostigmine and narcotics. The intravenous analgesic propofol is as of now the least emetogenic general soporific. These prescriptions are thought to invigorate the chemoreceptor trigger zone (CTZ). This zone is on the floor of the fourth ventricle and is successfully outside of the blood-mind obstruction. This makes it inconceivably touchy to poison and pharmacological incitement. There are various synapses, for example, histamine, dopamine, serotonin, acetylcholine, and the more as of late found neurokinin-1 (substance P).
