New breathing tube may spare your throat during lung surgery
NCT ID NCT07117539
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether using a laryngeal mask with a special bronchial blocker causes less sore throat and hoarseness after lung surgery compared to the standard double-lumen tube. 270 adults having lung surgery took part. The goal was to see which device leads to fewer throat injuries in the first 24 hours after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- visual bronchial blocker (VBB) device
- What this could lead to
- If it works, this could lead to a standard way to reduce sore throat and hoarseness after lung surgery.
- What could go wrong
- This is a completed study comparing two devices, not a new treatment. The benefit is limited to short-term comfort, not curing the lung condition.
