Comparing oxygen therapy effects on sleep apnea after bariatric surgery

Comparison of Apnea-Hypopnea Index, in Patients With Potentially Undiagnosed Obstructive Sleep Apnea, Treated With or Without Preventive Oxygen Therapy, During the First Night After Bariatric Surgery

NA · Rijnstate Hospital · NCT06432933

What this trial studies

This trial aims to determine the necessity of preventive oxygen therapy during the first postoperative night for patients undergoing bariatric surgery who may have undiagnosed obstructive sleep apnea (OSA). Participants will be randomized into two groups: one receiving standard care with oxygen therapy and the other receiving no oxygen therapy. The primary focus is to compare the Apnea-Hypopnea Index (AHI) between the two groups, while also assessing differences in sleep architecture. The study seeks to clarify the best perioperative management strategy for patients with potential OSA.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for primary bariatric surgery who do not have treated obstructive sleep apnea.

Not a fit: Patients with diagnosed obstructive sleep apnea who are already receiving treatment will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could optimize postoperative care for bariatric surgery patients, potentially reducing complications related to sleep apnea.

How similar studies have performed: Previous studies have shown that monitoring and oxygen therapy can be safe and cost-effective, but this specific approach in the bariatric population is novel.
