What this trial studies

This clinical trial investigates the effectiveness of the erector spinae plane block (ESPB) combined with dexmedetomidine in reducing chronic postsurgical pain (CPSP) in breast cancer patients undergoing mastectomy. The study aims to determine if this nerve block technique can improve pain management and enhance the quality of life for patients post-surgery. Participants will be randomly assigned to receive either the ESPB intervention or standard care, with outcomes measured over time to assess pain levels and overall recovery. The trial builds on previous findings that suggest regional anesthesia may help prevent CPSP and improve long-term outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 scheduled for unilateral mastectomy due to primary breast cancer.

Not a fit: Patients with previous breast surgeries, chronic opioid dependence, or contraindications to the erector spinae plane block will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of chronic pain in breast cancer patients after surgery, improving their quality of life.

How similar studies have performed: Previous studies have shown promising results with similar nerve block techniques in reducing chronic pain after breast surgery, indicating potential for success in this trial.
