Summary
Brief summary
There is little evidence that indicates which anti-emetic (a drug to treat nausea and vomiting) is most effective in the Emergency and pre-hospital setting despite the widespread clinical use of the agents. The aim of this study is to undertake a randomised controlled trial in the pre-hospital setting to evaluate the efficacy of 3 commonly used anti-emetics.
