Can a simple inhalation prevent oxygen drops in obese patients during lung surgery?
NCT ID NCT04583046
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether inhaling iloprost, a drug that widens blood vessels in the lungs, can improve oxygen levels in obese patients during one-lung ventilation for lung surgery. 78 participants were randomly assigned to receive either iloprost or a saltwater placebo. The researchers measured oxygen in the blood and other breathing parameters to see if iloprost reduces the risk of dangerously low oxygen.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- iloprost inhalation
- What this could lead to
- If successful, this could point toward a way to prevent dangerously low oxygen levels in obese patients during lung surgery.
- What could go wrong
- This is a small, early-stage study focused on short-term oxygen measurements, not long-term outcomes. The results may not apply to all patients or surgeries.
