Intranasal Ketamine for Acute Traumatic Pain

Summary

Introduction: Ketamine has been well studied for its efficacy as an analgesic agent. However, intranasal (IN) administration of ketamine has only recently been studied in the emergency setting. Objective: To elucidate the efficacy and adverse effects of a sub-dissociative dose of IN Ketamine compared to IV and IM morphine. Methods: A single-center, randomized, prospective, parallel clinical trial of efficacy and safety of IN ketamine compared to IV and IM morphine for analgesia in the emergency department (ED). A convenience sample of 90 patients aged 18-70 experiencing moderate-severe acute traumatic pain (≥80mm on 100mm Visual Analog Scale \[VAS\]) were randomized to receive either 1.0mg/kg IN ketamine, 0.1mg/kg IV MO or 0.15mg/kg IM MO. Pain relief and adverse effects were recorded for 1 hour post-administration. Primary Outcomes: The primary outcome was efficacy of IN ketamine compared to IV and IM MO, measured by "time-to-onset" (defined as a ≥15mm pain decrease on VAS), as well as time to and degree of maximal pain reduction.
