Brief summary
This study will compare two different ways to relieve nausea and vomiting in the Emergency Department. The usual treatment for nausea/vomiting is a drug called Zofran, but new studies have suggested that smelling alcohol pads can also help to relieve nausea and vomiting.
Detailed description
Emergency physicians commonly use medications to alleviate nausea and vomiting. The medication Ondansetron is used in the emergency department and after surgery for this purpose. Inhaled isopropyl alcohol has been successfully used to decrease nausea and vomiting after surgery. No trial has compared inhaled isopropyl alcohol to Ondansetron in a clinical trial. The author proposes to prospectively investigate extension of the established antiemetic efficacy of inhaled isopropyl alcohol for undifferentiated nausea in Emergency Department patients to the 30-minute post-intervention point that has been reported to be the frequent juncture of symptom relief. By introducing prolonged intervention, and re-dosing of established benefit, into this research, the author aims to reproduce the sustained antiemetic efficacy of inhaled isopropyl alcohol for undifferentiated nausea as demonstrated for post-operative nausea and vomiting.
Interventions
DRUGOral Dissolvable Tablet Zofran (ondansetron)
Single dose 4 mg tablet at 0 minutes.
OTHERInhaled Isopropyl Alcohol (IPA)
Three doses within 60 minutes. Doses will occur at 0 minutes, 30 minutes, and 60 minutes. Each dose consists of 3 inhalations of one IPA prep pad. A new prep pad is used at each dose.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Nausea Severity | 60 minutes | Patient's nausea severity will be assessed at three time points by the study personnel using a verbal nausea rating scale over the course 60 minutes. Severity is scored 0-10 (0 = no nausea; 10 = severe nausea). Time points are at 0 minutes, 30 minutes, and 60 minutes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Emesis Event | 60 minutes | Total number of emesis will be recorded for the 60 minute participation. |
