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.
Official title: A Randomized, Double Blind, and Placebo-Controlled Trial Comparing Ondansetron, Metoclopramide and Promethazine for the Treatment of Nausea and Vomiting in the Adult Emergency Department.
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: 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.
Minimum age: 18 Years.
Maximum age: N/A.
- All patients age 18 or older who present to the ED with a complaint requiring
antiemetic treatment who do not meet the exclusion criteria.
- Patients less than 18 years of age
