Brief summary (from the registry)

The investigators previous research study comparing the efficacy of intravenous ketamine to morphine showed ketamine to provide equivalent relief of moderate to severe acute pain in emergency department patients. A second study by the investigators showed that increasing the time of administration of the ketamine, from a push injection to a drip infusion, will minimize the adverse effects experienced by recipients of ketamine. The investigators now aim to see if nebulized subdissociative-dose ketamine administered as a single agent in a dose of 1.5 mg/kg via Breath-Actuated Nebulizers (BAN) over 5-15 minutes will provide a better pain relief in comparison to 1 mg/kg and 0.75 mg/kg doses or if the lower doses are equally as effective.
