Opioid-free anesthesia for abdominal aortic aneurysm repair

Effect of a Perioperative Opioid Free Anesthesia-Analgesia (OFA-A) Strategy on Surgical Stress Response in Elective Open Abdominal Aortic Aneurysm Repair: A Prospective Randomized Study

Phase 4 Interventional University of Crete · NCT04894864

This study is testing a new way to manage pain during and after surgery for abdominal aortic aneurysm repair without using opioids, to see if it helps patients recover better.

What this trial studies

This clinical trial investigates the effects of an opioid-free anesthesia-analgesia strategy on surgical stress and postoperative outcomes in patients undergoing elective open abdominal aortic aneurysm repair. The study compares traditional opioid-based anesthesia with a multimodal approach that utilizes various anesthetic and analgesic agents to minimize opioid use. By focusing on reducing the inflammatory response associated with surgical trauma, the trial aims to improve patient recovery and reduce complications. The research is conducted at the University of Crete, involving patients aged 40 to 85 who meet specific eligibility criteria.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 40 to 85 who are scheduled for elective open abdominal aortic aneurysm repair.

Not a fit: Patients who are immunocompromised, have active infections, or suffer from chronic inflammatory conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved postoperative recovery and reduced complications for patients undergoing high-risk abdominal surgeries.

How similar studies have performed: Other studies have shown promising results with opioid-free anesthesia approaches, indicating potential for success in this novel application.
