Can a numbing spray make breathing tube insertion safer?
NCT ID NCT07154628
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether spraying lidocaine, a numbing medicine, on the vocal cords before placing a breathing tube can reduce pain and blood pressure spikes during robotic surgery. Eighty adults scheduled for robotic surgery will be randomly assigned to receive either lidocaine or a saltwater spray. The goal is to see if this simple step makes intubation smoother and more comfortable.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
lidocaine spray
What this could lead to
If it works, this could provide a simple way to reduce pain and stress during intubation for robotic surgery.
What could go wrong
This is a small, early-phase trial with only 80 participants, so results may not apply widely. Lidocaine can rarely cause allergic reactions or side effects.
