Using dexmedetomidine and dexamethasone to improve pain management in upper limb surgery

Comparison of the Anesthetic Effects of Dexmedetomidine and Dexamethasone Added as Adjuvant to Ultrasonography-Guided Infraclavicular Brachial Plexus Block in Upper Limb Surgery

Umraniye Education and Research Hospital · NCT06779604

This study is testing whether adding two medications, dexmedetomidine and dexamethasone, to a nerve block can help people having upper limb surgery manage their pain better after the operation.

What this trial studies

This study investigates the effects of adding dexmedetomidine and dexamethasone to an infraclavicular brachial plexus block for patients undergoing upper extremity surgery. The focus is on evaluating the onset time, total duration of the block, and the time until the first analgesic is needed. The infraclavicular block is preferred for its effectiveness in providing anesthesia and analgesia while minimizing risks associated with other approaches. The study aims to enhance postoperative pain management through this combined approach.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 years with ASA physical status I-II undergoing upper extremity surgery.

Not a fit: Patients with significant comorbidities, prior nerve injuries, or those outside the age range may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved pain control and reduced need for additional analgesics after upper limb surgery.

How similar studies have performed: Other studies have shown promising results with similar adjuvant approaches in nerve blocks, suggesting potential for success in this study.
