Registration Number
NCT00655642
Lead Sponsor
Vanderbilt University
Brief Summary

The purpose of this study is to compare the effectiveness of ondansetron, metoclopramide, and promethazine for the treatment of nausea in the adult emergency department population.

We hypothesize that a single intravenous dose of ondansetron is more effective in reducing nausea than a single IV dose of metoclopramide, promethazine or normal saline placebo in undifferentiated adult emergency department patients.

Primary Outcome Measures
NameTimeMethod
Change in Visual Analog Scale (VAS) Score for Nausea. This Was Calculated by Subtracting the Patient's Reported Score on the 30 Minute VAS From the Patient's Reported VAS Score on Their Baseline VAS.Baseline and 30 minute assessments

Participants independently rated their nausea severity on separate scales at the baseline and 30-minute evaluations to prevent the baseline VAS score from influencing the 30-minute mark. The VAS had the words "Least Severe" on the left and "Most Severe" on the right. The possible values range from 0 to 100mm with 0 at the "Least Severe" extreme and 100 at the "Most Severe" extreme. Investigators instructed the participant to draw a single vertical line through the point on the 100mm scale that corresponded to their nausea severity at the times of measurement (Baseline and 30 minutes).
