Low Dose Ketamine as an Adjunct to Opiates for Acute Pain in the Emergency Department

This study investigates the use of low doses of ketamine, along with opiate pain medication, is more effective at controlling the acute pain of patients in the emergency department than opiate pain medication alone. In addition, this study examines whether patients treated with low doses of ketamine, along with opiate pain medication, will require less opiate pain medication to control their pain, and whether these patients are equally happy with their pain control as patients who receive only opiate pain medication.
