Laryngopharyngeal injury after breathing tube under anesthesia
Part of Brain & nervous system, Cancer, Digestive system, Ear, nose & throat, Hormones & metabolism, Lungs & breathing clinical trials.
This study looks at throat and voice box injuries that can happen after having a breathing tube during surgery. It may help doctors understand why some people experience hoarseness, sore throat, cough, or choking after non-ear-nose-throat operations.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You had general anesthesia with a breathing tube between October 2015 and September 2025 at the First Affiliated Hospital of Zhejiang University.
- After surgery, you needed to see an ear, nose, and throat doctor for throat problems like hoarseness, sore throat, cough, or choking when drinking.
- Your surgery was for something other than ear, nose, or throat problem.
- You did not have a throat or voice box condition before surgery (like a growth, polyp, tumor, or vocal cord paralysis).
- You did not have a tracheostomy (a tube in your neck to help you breathe) before or after surgery.
- If you had multiple surgeries, doctors can tell which one caused your throat symptoms.

This study looks at how your voice may change after a breathing tube is used during surgery. It focuses on people having thyroid, head and neck, or abdominal surgery to see if there are any voice changes that can be measured or noticed.
This study will check if keeping the tube in your windpipe at a certain pressure during surgery can help prevent problems like hoarseness or a sore throat after your procedure.
This study compares two types of breathing tubes used during general anesthesia to see which works better for people having trauma surgery. It aims to find which tube provides safer and easier airway management during the procedure.
This trial studies how to predict who is most likely to develop a noisy, tight throat (stridor) after doctors remove the breathing tube following a jaw-stabilizing surgery. It may help clinicians spot higher-risk patients earlier so they can take preventive steps.
This study tests whether adjusting the air pressure in a breathing tube used during ear surgery reduces sore throats and other side effects. It may help find the safest way to use this tube for people having ear surgery.
This trial is testing different types of breathing tubes used during thyroid surgery in women. It aims to find which tube works best to keep the airway safe and reduce side effects.
