Evaluating aminophylline's effects on lung function in obese patients during bariatric surgery

Impacts of Aminophylline on Perioperative Lung Mechanics in COPD Morbidly Obese Patients Undergoing Laparoscopic Bariatric Surgery: A Prospective Randomized Double Blinded Trial

Not applicable Interventional Tanta University · NCT06125665

This study is testing if adding aminophylline to a common medication during weight loss surgery can help improve lung function and oxygen levels in obese patients with breathing problems.

What this trial studies

This study aims to assess the impact of adding aminophylline to dexmedetomidine intravenous infusion during laparoscopic bariatric surgery on the oxygenation and lung mechanics of morbidly obese patients with chronic obstructive pulmonary disease (COPD). The research focuses on patients aged 20 to 60 who are scheduled for surgery and have a BMI greater than 40 kg/m2. By examining the combined effects of these medications, the study seeks to improve recovery outcomes for patients with respiratory complications related to obesity. The methodology includes monitoring lung function and oxygenation levels during and after the surgical procedure.

Who should consider this trial

Good fit: Ideal candidates are morbidly obese patients aged 20 to 60 with a BMI over 40 kg/m2 and diagnosed obstructive lung disease.

Not a fit: Patients with significant coexisting diseases, arrhythmias, or those allergic to the study medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance postoperative recovery and lung function in morbidly obese patients with COPD undergoing bariatric surgery.

How similar studies have performed: Previous studies have shown positive outcomes with dexmedetomidine in similar patient populations, but the combination with aminophylline is less commonly tested.
