Comparing high flow nasal oxygen to endotracheal intubation during laryngeal surgery

Comparison of High Flow Nasal Oxygenation Versus Endotracheal Intubation on Recovery Profiles in Laryngeal Microsurgery

Not applicable Interventional Ajou University School of Medicine · NCT05559502

This study tests if using high flow nasal oxygen can help patients recover with less coughing after laryngeal surgery compared to the usual method of putting a tube in their throat.

What this trial studies

This study investigates the effects of high flow nasal oxygenation (HFNO) versus endotracheal intubation (ET) on recovery profiles in patients undergoing laryngeal microsurgery. It aims to determine if HFNO can reduce coughing during emergence from anesthesia compared to traditional ET methods. The study involves administering total intravenous anesthesia (TIVA) with propofol and remifentanil while monitoring postoperative outcomes such as cough and sore throat. The hypothesis is that HFNO will provide a safer and more effective alternative to ET in this surgical context.

Who should consider this trial

Good fit: Ideal candidates are patients classified as American Society of Anesthesiologists 1 or 2 who require general anesthesia for laryngeal microsurgery.

Not a fit: Patients with major cardiovascular, pulmonary, or cerebrovascular diseases, as well as those undergoing laser laryngeal surgery or with morbid obesity, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved recovery experiences and reduced complications for patients undergoing laryngeal microsurgery.

How similar studies have performed: While the use of HFNO in various surgical contexts has shown promise, this specific comparison in laryngeal microsurgery is relatively novel and has not been extensively tested.
