Summary

This study tests whether using a smaller breathing tube during thyroid surgery can lower the chance of a sore throat afterward. 180 women having thyroid surgery will be randomly assigned to receive a tube with an inner diameter of 6.0, 6.5, or 7.0 millimeters. Researchers will check how many women have a sore throat at 1, 6, 24, and 48 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
tracheal tube (breathing tube) with inner diameters of 6.0mm, 6.5mm, or 7.0mm
What this could lead to
If smaller tubes work better, this could lead to a simple change in practice to reduce sore throat after thyroid surgery in women.
What could go wrong
This is a small, single-center trial. The benefit may be small or not apply to all patients. There is no new drug or treatment being tested.
