Clinical Trial Summary

Anterior shoulder dislocation (ASD) is a common situation in the emergency department (ED). Quick reductions lead to reduced mid and long term complications. No technique is superior to one another. Inhaled nitrous oxide can deal with pain reduction and anxiety but its efficacy is not optimal, with safety issues. Virtual reality hypnosis (VRH), by distracting patients from their pain, may lead to a better muscular relaxation and an easier ASD reduction.

Our first objective is to evaluate the clinical interest of VHR compared to nitrous oxide, in ASD reduction. Our second objective is to evaluate the safety of VRH in ASD reduction.

Patients over 18 years presenting an ASD < 24 hours, will be illegible for enrollment in an open multicenter randomized controlled trial, conducted in the Great East Region in France.

Intervention

Procedure:
• Virtual reality hypnosis
VRH offers predefined hypnosis sessions with no need of trained physician or nurse or caregiver mobilization. Consisting of a headset including headphones and a virtual reality screen, VRH allow patients to select a visual and sound environment (e.g.: tropical beach, space, underwater…) into which the hypnotic speech is delivered. That way, the patient's attention is distracted and muscular relaxation is obtained, a major relaxation factor. HRV is simple, quick, and presumably safe.

Drug:
• Nitrous oxide
inhalation of NO usually used to help with ASD reduction but inhaled NO has safety and maintenance issues.
