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.

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