Abstract
Introduction: Postoperative nausea and vomiting is one of the most common problems in postoperative period. Patients' who are at high risk of PONV, may receive anti-nausea and vomiting drugs. The most common drug is Metoclopramide, but it,s extrapiramidal signs and side effects such as lethargy, dizziness and headache especially in children lead us to perform this study, in order to compare Dexamethasone and Metoclopramide effects in PONV prevention. Materials and Methods: This study was a double-blind randomized controlled clinical trial. 262 patients (2-25 years) in ASA class I,II which were candidates for ENT, eye and laparatomy surgeries, divided into two groups randomly. One group received 0.1 mg/kg Dexamethasone IV and the other group received 0.1mg/kg Metoclopramide IV, 10-15 minuets before operation ending time. During recovery, the frequency of PONV was assessed. Data was analyzed by Pearson test. Results: PONV frequency in the two groups had no significant difference. Also PONV rate in the two groups had no significant difference in male and female. Conclusion: In prevention and treatment of PONV, Dexamethasone effect was same as Metoclopramide. Considering low expense, avalibility and low side effects, Dexamethasone is a proper substitute for Metoclopramide in surgeries with high risk of PONV.

Abstract
Background: Post operative nausea and vomiting (PONV) is a very common and distressing complication after surgeries which may result in more serious problems such as incisional hernia wound dehiscence and aspiration. Cataract surgery following increase in intraocular pressure is sensitive to POVN. This study was designed to evaluate the effect of capsicum ointment on Korean acupressure points in reducing PONV and the amont of anti- emetic medications was used. Methods and Materials: This study is a double-blinded clinical trial which was done on 200 patients who were referred to Amir Kabir hospital for cataract surgery. The patients were randomized assigned to two groups, one who received capsicum ointment and the other placebo (vaseline ointment) at the pressure points (K-K9 and K-KD2). After applying the ointments and during the first 12 hours after the operation the patients were assessed for the incidence and intensity of PONV. Results: The incidence of nausea and vomiting during the first 6 and 12 hours was higher in the placebo group in compare to the capsicum group (p=0.001). Nausea scores were also higher in the 6 and 12 hours in the placebo group (p=0.0005). Uses of metoclopramide was significant higher in the placebo group in compare to the capsicum group (p=0.001). There was no significant difference between the two groups for vomiting during first 12 hours ofter opration. Conclusion: Stimulating of both K-D2 & K-K9 Korean acupressure points simultaneously is a simple, noninvasive, cheap and effective method for reducing PONV.

Abstract
Background: Postoperative nausea and vomiting (PONV) is one of the most common complications in the patients undergoing strabismus surgery. The aim of current study was comparing supplemental 80% and 40% oxygen on reducing postoperative nausea and vomiting in the pediatrics undergoing strabismus surgery.
Materials and Methods: In this clinical trial study, 100 pediatric patients scheduled for strabismus surgery under general anesthesia were allocated randomly into two parallel supplemental 80% and 40% oxygen groups during surgery. PONV in patients was compared until 24hrs after operation.
Results: In the first 6hrs postoperatively, PONV in the supplemental 40% and 80% oxygen groups were 48.8% and 30.6% respectively, also were 20.8% and 12.2% in the 6 to 24hrs postoperatively. Therefore, there were no significant differences between both groups in regarding of PONV in 6hrs and 6 to 24hrs postoperatively (p values were 0.18 and 0.25, respectively).
Conclusion: According to our results, there is no any difference between 40% and 80% oxygen postoperatively in the pediatrics undergoing strabismus surgery.
