- Brief Summary
Article Summary
1. Tracheal tube-related tongue injury is a common clinical complication that would lead to serious events such as dysphagia, respiratory dysfuncion and macroglossia.
2. There is a lack of qualitative and quantitative risk assessment of tracheal tube-related tongue injury.
3. This is a protocol of a single-center, prospective, paralled-group clinical trial based on the measurement of dynamic changes in pressure between the tracheal tube and the tongue in different position during the surgery.
4. The primary endpoint is tracheal tube-related tongue injury, secondary outcomes include the time to first successful recovery of oral intake of fluids and solid food and airway-related events.
5. This trial aims to find the best indicators for tracheal tracheal tube-related tongue injury and to provide solid basis for optimizing airway protection strategies and surgical positioning.
- Detailed Description
Background Tracheal tube-related tongue injury can lead to post-intubation pharyngeal dysfunction, postoperative macroglossia, or stridor after extubation. Possible mechanisms include increased oral pressure, obstruction of venous and lymphatic return in the neck, leading to severe throat pain, dysphagia, and respiratory function impairment. There is a lack of indicators and clinical awareness of this issue. Therefore we have designed this study to accurately monitor the tracheal tube-tongue pressure in different surgical position during general anesthesia.
Method This is a prospective, single-center observational study. Fifty-four patients undergoing elective surgery in general anesthesia for more than 2 hours with endotracheal tube applied will be enrolled. Patients will be divided into supine position (Supine group) and the high-risk positions (Flexion group) groups. Dynamic changes in pressure between the tracheal tube and the tongue are measured. All patients will be followed up until 7 days after operation. Primary endpoint is tracheal tube-related tongue injury. Secondary outcomes include the time to first successful recovery of oral intake of fluids and solid food, and airway-related events.
Discussion The study aims to explore the risk factors and pressure thresholds for tracheal tracheal tube-related tongue injury.

Group Intervention Description Supine group Tracheal tube-tongue pressure is measured using a computerized occlusal analysis system based on T-Scan® technique, suitable for multi-point real-time monitoring of intraoral pressure. Fifty-four patients undergoing elective surgery in general anesthesia for more than 2 hours with endotracheal tube applied in China-Japan Friendship Hospital will be enrolled (See in Sample Size calculation). Patients will be divided into two groups according to the surgery: supine position (Supine group) Flexion group Tracheal tube-tongue pressure is measured using a computerized occlusal analysis system based on T-Scan® technique, suitable for multi-point real-time monitoring of intraoral pressure. The high-risk positions (Flexion group) which include patients scheduled for surgery under the prone position, cervical traction position, and beach chair position.
- Primary Outcome Measures
Name Time Method tracheal tube-related tongue injury Starting from the time after surgery till post-operative day 7 (POD7) The primary composite endpoint is assessed as incidence of tracheal tube-related tongue injury, which is either the state of severe sore throat (VAS≥4), dysphagia after extubation, or any of the symptoms of macroglossia.
- Secondary Outcome Measures
Name Time Method time of first smooth water intake Starting from the time after surgery till post-operative day 7 (POD7) time of first smooth water intake
time of first smooth solid food intake Starting from the time after surgery till post-operative day 7 (POD7) time of first smooth solid food intake
airway related events Starting from the time after surgery till post-operative day 7 (POD7) bronchospasm, aspiration, secondary intubation, respiratory tract infection, respiratory insufficiency, prolonged oxygen therapy, etc.
