Randomized Controlled Trial Multicenter Study Comparative Study
Antiemetic Use for Nausea and Vomiting in Adult Emergency Department Patients: Randomized Controlled Trial Comparing Ondansetron, Metoclopramide, and Placebo.
We compare efficacy of ondansetron and metoclopramide with placebo for adults with undifferentiated emergency department (ED) nausea and vomiting. ⋯ Reductions in nausea severity for this adult ED nausea and vomiting population were similar for 4 mg intravenous ondansetron, 20 mg intravenous metoclopramide, and placebo. There was a trend toward greater reductions in VAS ratings and a lesser requirement for rescue medication in the antiemetic drug groups, but differences from the placebo group did not reach significance. The majority of patients in all groups were satisfied with treatment.
