the drug, and those registering the signs and symptoms of the patients were unaware of the medicine used in each group. Patients with digestive problems, a history of treatment with antiemetics and nausea in the preceding 24 hours, or obesity (BMI>40) were excluded from the study. A written consent was obtained from all the patients. The study was approved by the Ethics Committee, Inhibitors,research,lifescience,medical Tabriz University of Medical Sciences. Figure 1: The Flowchart of the design and the protocol of the study. Before the induction of anesthesia, 4 mg of ondansetron, 8 mg of dexamethasone or distilled water were administered intravenously to respective groups. The volume of the administered drug was 3 ml in all Inhibitors,research,lifescience,medical the three groups. In each group, premedication was given using midazolam at 0.15 mg/kg and fentanyl at 1-2 ∞g/kg. Induction

was PDK 1 inhibitor carried out with propofol (1-2.5 mg/kg) and atracurium (0.5 mg/kg). Anesthesia maintenance for both groups was performed using Total Intravenous Inhibitors,research,lifescience,medical Anesthesia method and through propofol (10-20 ∞g/kg/min) and remifentanyl (0.5 ∞g/kg/min). Administration of anesthetics for maintenance continued until the last stitch of the operation. Extubation was performed after creating inhaling power of 20 cm of water, and all the patients were dismissed from PACU provided that they had acquired at least a score of 9. During the anesthetic Inhibitors,research,lifescience,medical maintenance, no inhalation anesthetic drugs and N2O were used, and ventilation was carried out with 100% oxygen. Using a questionnaire, all instances of nausea and vomiting were recorded carefully every few hours for 24 hours until the patient was discharged to the ward. The intensity of vomiting was evaluated through the Bellville scoring scale Inhibitors,research,lifescience,medical (lack of nausea and vomiting=0, nausea=1, nausea with belching=2, and vomiting=3). Data were collected on the type of the surgical operation, age, NPO duration, ASA, induction and duration of anesthesia, duration of the operation, blood pressure before and after the operation, respiratory rats before the operation, saturation Sclareol of peripheral oxygen (SPO2) before

the operation, body temperature before the operation, duration of recovery, blood pressure five minutes after induction and after extubation, SPO2 five minutes after extubation, SPO2 at discharge from recovery, presence and the intensity of nausea or vomiting at 0-2, 2-8, 16-24 hours after the operation. Data, presented as Mean±SD or frequency and percentage, were analyzed using SPSS (Version 15, Chicago, IL, USA) statistical program. The quantitative variables were compared using paired t test or one-way ANOVA followed by Tukey test for pairwise comparisons. The comparison of qualitative variables was performed using contingency tables, chi-square, or Fisher’s exact test. A p value of ≤0.05 was considere statistically significant.
