Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-65 with a BMI of 30 kg/m² or higher, scheduled for elective bariatric surgery.

Probably not a fit

Patients who are pregnant, breastfeeding, or have chronic opioid use or severe comorbidities may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study investigates how different anesthesia methods impact inflammation in patients undergoing bariatric surgery. Participants will be randomly assigned to receive either opioid-free anesthesia, intravenous anesthesia with opioids, or inhalational anesthesia with opioids. Blood samples will be taken to measure inflammation-related substances and heart rate variability will be monitored to assess the body's stress response. The goal is to identify anesthesia strategies that may enhance recovery by modulating inflammation.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery outcomes for patients undergoing bariatric surgery by minimizing inflammation.

How similar studies have gone: While the approach of using different anesthesia techniques is not entirely novel, the specific focus on inflammation modulation in bariatric surgery is relatively untested.
