Intranasal Sufentanil Pain-management at Entrance of Emergency Department : Influence on Pain-relief Delay

Non-invasive and simple, intranasal (IN) route of administration seems promising for pain management in the Emergency Department (ED), especially when used precociously by triage nurse to rapidly deliver the first opioid dose to severely painful patients. This randomized double-blind placebo-controlled study will focus on severe traumatic pain experienced by adults admitted in our ED. We hypothesized that, in addition to traditional morphine titration, a single dose of IN sufentanil given at triage would significantly increase the proportion of patients relieved 30 minutes after their ED admission. Time to discharge, proportion of side effects and satisfaction rates will also be recorded.
