Comparing high flow nasal cannula and conventional oxygen therapy for patients with obstructive sleep apnea after surgery

Comparative Study Between High Flow Nasal Cannula and Conventional Oxygen Therapy in the Postoperative Management of Patients With Mild to Moderate Obstructive Sleep Apnea

Not applicable Interventional Ain Shams University · NCT06306651

This study is testing if high-flow nasal cannula therapy can help patients with obstructive sleep apnea breathe better after surgery compared to regular oxygen therapy.

What this trial studies

This study compares the effectiveness of high-flow nasal cannula therapy and conventional oxygen therapy in managing oxygen saturation levels in postoperative patients with mild to moderate obstructive sleep apnea. It focuses on measuring the oxygen desaturation index, length of ICU stay, and the need for supplemental CPAP support. The study aims to determine if high-flow nasal cannula therapy can provide a more comfortable and effective alternative to CPAP for patients who are non-adherent. The research is conducted in the postoperative ICU setting, where patients are at risk for complications due to their condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 21 to 40 with mild to moderate obstructive sleep apnea undergoing elective non-cardiac surgeries.

Not a fit: Patients with severe obstructive sleep apnea, those dependent on home ventilation, or those with significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve postoperative care and outcomes for patients with obstructive sleep apnea by providing a more effective and comfortable oxygen therapy option.

How similar studies have performed: While there is existing evidence supporting the use of CPAP, the effectiveness of high-flow nasal cannula therapy in this specific postoperative context is less established, making this a novel approach.
