Which oxygen method keeps patients safer during throat surgery?
NCT ID NCT06609915
First seen Aug 07, 2026 · Last updated Sep 02, 2026 · Updated 2 times
Summary
This trial compares two ways of delivering oxygen during tubeless throat surgery: high-flow nasal oxygen and a special jet ventilation technique. The goal is to see which method is safer and more efficient by measuring how often surgery is interrupted due to oxygen issues. Forty adults having elective tubeless laryngotracheal surgery will be randomly assigned to one of the two methods. The study will track oxygen levels, interruptions, and any need to switch airway strategies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Two oxygen delivery methods: supraglottic superimposed high-frequency jet ventilation (using the Monsoon 4 device) and high-flow nasal oxygen (using the Optiflow device)
- What this could lead to
- If one method proves safer and more efficient, it could become the preferred way to keep patients oxygenated during tubeless throat surgery, reducing interruptions and complications.
- What could go wrong
- This is a small trial with only 40 patients, so results may not apply to everyone. Both methods carry risks like oxygen drops or airway issues, and the study is not designed to prove long-term benefits.
