Gestion de l'analgésie dans les dislocations d'épaule en urgence

Intravenous analgesia (Paracetamol, NSAIDs, opioids) is preferred for patients during the treatment and reduction stages of anterior shoulder dislocation. Additionally, patients may receive regional anesthesia and analgesia (lidocaine, bupivacaine). The route and dosage of analgesic administration are chosen by the attending physician managing the patient. In this study, investigators plan to observationally evaluate the analgesic management of patients without intervening in the method and dosage chosen by the primary treating physician. Patients receiving analgesia will be chosen according to preffered treatment at emergency department. The study population will consist of patients presenting to the emergency department with shoulder dislocation who receive analgesia and fall into the following 4 treatment groups. These 4 group will consist in: 1. ketamine group 2. interscalene nerve block group 3. suprascapular nerve block group 4. intraarticular lidocaine injection group. The study will compare these 4 treatment methods in terms of analgesia management, reduction time, comfort, and length of hospital stay for patients presenting to the emergency department with shoulder dislocation and receiving analgesia. The researcher will not interfere with the treatment decision made by the responsible physician or the treatment process
