A dab of gel on the breathing tube might spare surgery patients a sore throat — a trial puts it to the test.
NCT ID NCT07040631
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This trial tests whether applying a hyaluronic acid gel (Endotra Gel) to the breathing tube before general anesthesia can reduce sore throat, hoarseness, and coughing after breast cancer surgery. About 132 adults undergoing breast cancer surgery will be randomly assigned to receive the gel or standard care. Researchers will track symptoms right after surgery and the next day to see if the gel improves comfort and recovery.
