Could a tiny dose of muscle relaxant make lung scopes safer?

NCT ID NCT07035301

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at whether giving a low dose of a muscle relaxant (rocuronium) during bronchoscopy—a procedure where a tube is inserted into the lungs—could reduce complications like throat spasms and coughing. 153 adults having elective bronchoscopy were split into two groups: one got the muscle relaxant, the other got a placebo. The goal was to see if the relaxant made the procedure smoother and safer.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Rocuronium (low-dose muscle relaxant)
What this could lead to
If it works, this could make bronchoscopy safer and more comfortable by reducing airway spasms and coughing during the procedure.
What could go wrong
This is a small, completed study with 153 participants, so results may not apply to all patients. Low-dose muscle relaxants still carry risks like breathing difficulties.
