Could a whiff of xenon replace the Pre-Surgery chill pill?
NCT ID NCT06080100
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers are testing whether inhaling a low dose of xenon gas can ease anxiety before laser vision correction. The trial enrolls 140 people who score high on stress and anxiety tests and are scheduled for ReLEx SMILE eye surgery. Participants receive either xenon or a standard anti-anxiety pill, and the team tracks stress markers like cortisol, blood sugar, and heart rhythm to compare the two approaches.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- inhaled xenon gas at a low, non-sleep-inducing dose
- What this could lead to
- If xenon works, it could offer a fast, non-pill way to calm patients before eye surgery and possibly other brief procedures.
- What could go wrong
- This is an early-stage trial with 140 people, so any benefit may be small or not hold up in larger studies. Xenon is a scarce, costly gas, and inhaling it carries its own risks.
