Antiemetics for reducing vomiting related to acute gastroenteritis in children and adolescents.Cochrane Database Syst Rev. 2006 Jul 19CD
Vomiting caused by acute gastroenteritis is very common in children and adolescents. Treatment of vomiting in children can be problematic and the use of antiemetics remains a controversial issue. There have been concerns expressed about apparently unacceptable levels of side effects such as sedation and extrapyramidal reactions, which are associated with some of the earlier generation of antiemetics.
To assess the effectiveness of antiemetics on gastroenteritis induced vomiting in children and adolescents.
We searched the Cochrane Central register of Controlled Trials (CENTRAL), which includes the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group Trials Register (searched 28 July 2005), MEDLINE (1966 to July 2005) and EMBASE (1980 to July 2005). Published abstracts from conference proceedings from the United European Gastroenterology Week and Digestive Disease Week were handsearched. Members of the Cochrane UGPD Group were contacted for details of any ongoing or relevant unpublished clinical trials.
Randomised controlled trials comparing antiemetics and/or placebo in children and adolescents, under the age of 18, with vomiting due to gastroenteritis.
DATA COLLECTION AND ANALYSIS
Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects data was collected from the studies.
Two trials involving 181 participants were included. Although no data were available for the precise time to cessation of vomiting (the primary outcome specified in the protocol for this review), one trial reported that the proportion of patients without vomiting over a 24 hour period was higher in the ondansetron and metoclopramide groups than placebo. In the second trial, ondansetron ensured complete anti-emesis for 8/12 (67%) patients within the first 4 hours and in 7/12 (58%) patients in the first 24 hr period. A few secondary outcomes were reported in the included trials.
