cause severe chest wall pain that can impair normal breathing, coughing, and lung function. While systemic opioids are commonly used to treat traumatic pain, their side effects, such as sedation and respiratory depression, can complicate recovery. Regional nerve blocks like the ultrasound-guided erector spinae plane block (ESPB) offer targeted pain relief while minimizing opioid requirements.\n\nThe purpose of this clinical trial is to compare the analgesic efficacy and respiratory outcomes of adding dexmedetomidine versus dexamethasone to bupivacaine during an ultrasound-guided ESPB in emergency department patients with acute traumatic rib fractures.\n\nParticipants aged 18 to 65 years presenting within 24 hours of rib injury will be randomly assigned to one of two groups:\n\n* Dexmedetomidine Group: Receives an ultrasound-guided ESPB with bupivacaine plus dexmedetomidine.\n* Dexamethasone Group: Receives an ultrasound-guided ESPB with bupivacaine plus dexamethasone.\n\nThe primary outcome is the duration of analgesia, measured as the time to the first request for rescue pain medication. Secondary outcomes include pain scores at rest and during coughing\u002Fdeep breathing, total 24-hour opioid consumption, diaphragmatic motion evaluated by ultrasound, respiratory recovery, and the incidence of adverse events over a 24-hour follow-up period.",[70,71,72],"Rib Fractures","Acute Pain","Thoracic Trauma",[74,75,76,77,78,79,80,81],"Erector spinae plane block","ESPB","Dexmedetomidine","Dexamethasone","Bupivacaine","Ultrasound-guided regional anesthesia","Rib fracture analgesia","Diaphragmatic excursion","NOT_YET_RECRUITING","2026-09-14",{"date":85,"type":86},"2026-09-18","ACTUAL",{"date":88,"type":63},"2026-10",{"date":90,"type":63},"2027-11",{"name":5,"class":6}]
