BACKGROUND Intrathecal morphine for caesarean delivery provides excellent postoperative analgesia but it is commonly associated with nausea and vomiting. This prospective, randomized, double blind study was carried out to compare the effectiveness of a combination of dexamethasone and ondansetron with dexamethasone alone for prevention of postoperative nausea and vomiting (PONV) following intra...

Background: Post-operative nausea and vomiting (PONV) following surgical operations requiring general anesthesia are common and distressing. The incidence of PONV may be as high as 70% during the first 24 hrs of tonsillectomy. Objective: This study determines the effects of intraoperative well-hydration on postoperative nausea and vomiting. Methods: 90 ASA I patients with age of 6-12 years sche...

We performed a cross-sectional study to explore a potential association between preoperative anxiety and postoperative nausea and vomiting (PONV). The study enrolled 51 unpremedicated children 5–16 yr old undergoing outpatient surgery and standardized general anesthesia. Anxiety of children was assessed in the preoperative holding area and during the induction of anesthesia. The incidence of na...

BACKGROUND During a previous study to define and compare incidence risks of postoperative nausea and vomiting (PONV) for elective laparoscopic and open cholecystectomy at two hospitals in Jamaica, secondary analysis comparing PONV risk in elective open cholecystectomy to that after emergency open cholecystectomy suggested that it was markedly reduced in the latter group. The decision was made t...

BACKGROUND Postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy (LC) has multifactorial etiology. Pain and use of opioids are among the important factors. OBJECTIVES The present study aimed to evaluate the efficacy of intrapritoneal (IP) injection of bupivacaine on PONV. PATIENTS AND METHODS This was a double-blind randomized clinical trial, conducted on 66 patients a...

UNLABELLED Supplemental oxygen maintained during and for 2 h after colon resection halves the incidence of nausea and vomiting. Whether supplemental oxygen restricted to the intraoperative period is sufficient remains unknown. Similarly, the relative efficacy of supplemental oxygen and ondansetron is unknown. We tested the hypothesis that intraoperative supplemental oxygen reduces the incidence...

INTRODUCTION Postoperative nausea and vomiting (PONV) is one of the most common complaints from patients and clinicians after a surgical procedure. According to the current Society of Ambulatory Anesthesia Consensus Guidelines, the general incidence of vomiting and nausea is around 30 and 50%, respectively; and up to 80% in high-risk patients. In previous studies, the reported incidence of PONV...

PURPOSE To compare the use of promethazine 6.25 mg intravenous (IV) (experimental group) with promethazine 12.5 mg IV (control group) among adult ambulatory surgery patients to control established postoperative nausea or vomiting (PONV). DESIGN/METHODS In a double-blind, randomized controlled trial (n = 120), 59 subjects received promethazine 6.25 mg and 61 subjects received promethazine 12.5...

background: the effects of different opioids on postoperative nausea and vomiting (ponv) and pain have not been conclusively determined. the aim of this study was to compare the effects of fentanyl, remifentanil or fentanyl plus morphine on the incidence of ponv and pain in women subjected to cesarean section under general anesthesia. methods: the study was a randomized clinical trial recruitin...
