Low Dose Ketamine for Management of Acute Severe Pain in the Emergency Department

• Status: Completed
• Trial end date: 2014-06-01
• Target enrollment: 0
• Participant gender: All

Summary

This study aims to address both the management and evaluation of pain. The primary aim of this study is to determine the efficacy of low dose ketamine in adults with moderate to severe pain in the emergency department as compared with parenteral opioids alone. Another aim is to examine the safety of low dose ketamine compared to opioids alone.

The investigators hypothesize that low dose ketamine will result in more effective pain control than morphine alone and will not be associated with an increase in adverse events.
