Opioid-free anesthesia for breast cancer surgery

A Comparative Evaluation of Opioid Free Anaesthesia Technique Versus the Conventional Technique in Oncological Breast Surgery

Not applicable Interventional University of Ioannina · NCT06404983

This study tests whether using opioid-free anesthesia during breast cancer surgery can help patients recover better and have fewer side effects compared to traditional anesthesia.

What this trial studies

This clinical trial investigates the effects of opioid-free anesthesia (OFA) compared to conventional general anesthesia (CGA) in patients undergoing breast cancer surgeries such as lumpectomy or mastectomy. The study aims to evaluate postoperative analgesic requirements, cognitive function, and adverse events in the first 48 hours after surgery. Additionally, it will assess intraoperative hemodynamics and the length of hospital stay. By avoiding opioids, the trial seeks to minimize the undesirable side effects associated with opioid use.

Who should consider this trial

Good fit: Ideal candidates include adult patients scheduled for breast cancer surgery under general anesthesia.

Not a fit: Patients who are under 18, have chronic pain requiring opioids, or have severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce opioid-related side effects and improve recovery outcomes for breast cancer surgery patients.

How similar studies have performed: There is growing interest and some preliminary success in opioid-sparing techniques, but this specific approach is still being evaluated.
