Background: Postoperative vomiting (POV) is a frequent side-effect of paediatric surgery and a leading cause of unplanned admission. Many antiemetic drugs have been studied, but less attention has been given to the effects on POV of the anaesthetic technique adopted. The aim of this study was to compare two different anaesthetic techniques in children under regional analgesia at risk for POV. Methods: We studied 135 children suffering from motion sickness or with a previous history of POV. The patients were randomized to receive inhalation anaesthesia (group S) with sevoflurane by LMA TM or intravenous (i.v.) anaesthesia with ketamine and propofol (group P). All the patients were treated with an ilio-inguinal block after induction of anaesthesia. Postoperatively, the children were followed by the nursing staff and by their parents, none of whom were aware of the anaesthesia technique used. Results: A significant decrease was observed in the incidence of early (0-6 h) and delayed (6-24 h) POV in those children who received i.v. sedation. There was no difference between the two groups in the level of analgesia either at the end of surgery or 2 h postoperatively. Conclusions: Anaesthesia based on propofol and ketamine is better than inhalation anaesthesia with sevoflurane by LMA for reducing POV in children at risk under an ilio-inguinal block. Tailoring the anaesthetic to the specific needs of children susceptible to POV should be considered before resorting to the routine use of expensive antiemetic prophylaxis.
Society for Ambulatory Anesthesia Guidelines for the Management of Postoperative Nausea and Vomiting
Anesthesia & Analgesia, 2007
The present guidelines were compiled by a multidisciplinary international panel of individuals with interest and expertise in postoperative nausea and vomiting (PONV) under the auspices of The Society of Ambulatory Anesthesia. The panel critically evaluated the current medical literature on PONV to provide an evidencebased reference tool for the management of adults and children who are undergoing surgery and are at increased risk for PONV. In brief, these guidelines identify risk factors for PONV in adults and children; recommend approaches for reducing baseline risks for PONV; identify the most effective antiemetic monotherapy and combination therapy regimens for PONV prophylaxis; recommend approaches for treatment of PONV when it occurs; and provide an algorithm for the management of individuals at increased risk for PONV. (Anesth Analg 2007;105:1615-28) Post operative nausea and vomiting (PONV) is a continuing concern in surgical patients and the management of this problem is still confusing. In the United States, more than 71 million inpatient and outpatient operative procedures are performed each year (1). Untreated, PONV occurs in 20%-30% of the

Introduction: Postoperative nausea and vomiting are frequent adverse effects of anesthesia and surgery. Impact is greater in pediatric populations compared to adults and the reported incidences are heterogeneous. Objective: To describe the incidence of postoperative vomiting in a pediatric population and to identify associated risk factors. Materials and methods: This prospective cohort study included 190 children aged 3 to 12 years undergoing surgery and anesthesia in a maternal and child health clinic in Bucaramanga (Colombia). The main outcome variable was postoperative vomiting. Data were analyzed using bivariate, multivariate analysis and logistic regression to assess the associated risk factors. Results: The overall incidence of postoperative vomiting was 18.95% (95% CI: 13.32 - 24.57), with a higher incidence at home vs. hospital (12.63% vs. 9.47%). After adjustment, associated risk factors were anesthesia time longer than 45 minutes (OR: 2.33; 95% CI: 1.10-4.90) and postoper...
