Comparison of Dexmedetomidine Versus Dexamethasone as Adjuvants to Bupivacaine in Ultrasound-Guided Erector Spinae Plane Block for Acute Pain Management in Patients With Traumatic Rib Fractures

Sponsor: Assiut University

Summary

Traumatic rib fractures 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. The 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. Participants aged 18 to 65 years presenting within 24 hours of rib injury will be randomly assigned to one of two groups: * Dexmedetomidine Group: Receives an ultrasound-guided ESPB with bupivacaine plus dexmedetomidine. * Dexamethasone Group: Receives an ultrasound-guided ESPB with bupivacaine plus dexamethasone. The 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/deep 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.
