Pain and Anxiety Management of Traumatic Emergency in a Pre-hospital Setting

Unexpected acute pain in an emergency setting causes anxiety, insecurity, and stress that can diminish perceptions of control over pain and diminish ability to decrease pain. This may interfere with the opioid treatment and poses the question of whether an anxiolytic drug added to the morphine titration could relief pain and/or anxiety. This randomized double-blind group clinical trial is designed to determine the efficacy and safety of hydroxyzine in addition to a conventional intravenous morphine titration protocol.
