Summary

This study tested whether putting the breathing tube (endotracheal tube) in the fridge before use could reduce sore throat after surgery. 116 adults having elective surgery took part. The researchers measured how many people had a sore throat and how bad it was in the hours after the tube was removed.

What this could lead to
If it works, this could offer a simple, low-cost way to reduce sore throat after surgery without medication.
What could go wrong
This is a small, completed study with no phase designation. The effect may be modest or not generalizable to all patients or surgeries.
