Antiemetics in Children With Acute Gastroenteritis: A Meta-analysis
Abstract
In this systematic review and NMA, we summarize the evidence supporting the use of ondansetron for achieving cessation of vomiting and reducing hospitalizations. CONTEXT: Several antiemetics have been used in children with acute gastroenteritis. However, there is still controversy over their use. OBJECTIVE: To determine the effectiveness and safety of antiemetics for controlling vomiting in children with acute gastroenteritis. DATA SOURCES: Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, Latin America and the Caribbean Literature on Health Sciences, and gray literature, until December 2018. STUDY SELECTION: We selected randomized clinical trials comparing metoclopramide, ondansetron, domperidone, dexamethasone, dimenhydrinate, and granisetron. DATA EXTRACTION: Two reviewers independently screened abstracts and full texts, extracted the data, and assessed the risk of bias. We performed pairwise and network meta-analysis using the random-effects model. RESULTS: Twenty-four studies were included (3482 children). Ondansetron revealed the largest effect in comparison to placebo for cessation of vomiting (odds ratio = 0.28 [95% credible interval = 0.16 to 0.46]; quality of evidence: high) and for hospitalization (odds ratio = 2.93 [95% credible interval = 1.69 to 6.18]; quality of evidence: moderate). Ondansetron was the only intervention that reduced the need for intravenous rehydration and the number of…
