Abstract
The common and distressing complications of postoperative nausea and vomiting (PONV) are the main concern of 40-70% of patients undergoing laparoscopic cholecystectomy (LC). The first step in preventing PONV after LC is to reduce the risk factors involving patient characteristics, surgical procedure, anesthetic technique, and postoperative care. Particularly, the use of propofol-based anesthesia can reduce the incidence of PONV after LC. Second, prophylactic antiemetics including antihistamines (dimenhydrinate), phenothiazines (perphenazine), butyrophenones (droperidol), benzamides (metoclopramide), dexamethasone, and serotonin receptor antagonists (ondansetron, granisetron, tropisetron, dolasetron, and ramosetron) are available for preventing PONV after LC. Third, antiemetic therapy combined with a serotonin receptor antagonist (ondansetron, granisetron) and droperidol or dexamethasone is highly effective in the prevention of PONV after LC. Fourth, acupressure at the P6 point is a nonpharmacologic technique that is as effective as ondansetron for preventing PONV after LC. Knowledge regarding the risk factors for PONV and antiemetics is needed for the management of PONV after LC.
