Summary

This study tests two simple, low-cost methods—chewing sugar-free gum or gargling cold water—before a bronchoscopy to see if they reduce sore throat and swallowing difficulty afterward. About 100 adults scheduled for diagnostic bronchoscopy will be randomly assigned to one of these interventions or standard care. Researchers will measure pain and satisfaction levels to determine if these easy steps improve patient comfort.

What this could mean

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

Active substance
chewing gum and cold water gargle
What this could lead to
If effective, these simple, low-cost methods could become standard practice to ease throat discomfort after bronchoscopy.
What could go wrong
This is a small, early-stage study with only 100 participants. The interventions may not significantly reduce symptoms compared to standard care.
