    Abstract:
    BACKGROUND AND GOALS: A relatively high incidence of postoperative nausea and vomiting (PONV) occurs in patients undergoing a laparoscopic cholecystectomy. Prophylaxis of PONV is usually achieved with a single-dose antiemetic drug administered during the surgical procedure. The aim of the current study was to compare the antiemetic activity of different 5-hydroxytryptamine-3 receptor antagonists with that of metoclopramide. MATERIALS AND METHODS: In a randomised, double-blind study, 75 patients received the following: Group M, 10 mg metoclopramide; Group K, 40 mcg . kg(-1) granisetron; and Group Z, 15 mcg . kg(-1) ondansetron intravenously (IV) diluted in 20 cc 0.9% NaCl (n = 25 of each) i.v. immediately before the induction of anesthesia. The standard general anesthetic technique, which consisted of sevoflurane in air-oxygen and a fentanyl perfusion, was used. Nausea, vomiting, and safety assessments were performed continuously during the first 24 hours after anesthesia. RESULTS: There were no statistically significant differences for demographic data, American Society of Anesthesiology (ASA), operation duration, or anesthesia time among the three groups (P > 0.05). Evaluated nausea and vomiting scores in the first 3-hour period revealed that each of the drugs had a similar antiemetic effect (P > 0.05). Nausea and vomiting scores, evaluated between the 4-24 hours, also revealed that the group M scores were obviously higher than groups K and Z (P < 0.001). A comparison of incidences of dose administrations were statistically not significant among the groups (P > 0.05). CONCLUSIONS: Granisetron, when given prophylactically, resulted in a significantly lower incidence of PONV than metoclopramide and ondansetron, whereas metoclopramide was ineffective. Garnisetron may be an effective treatment in the proflaxy of PONV.
