Numerous current studies have indicated that transecting the pulmonary plexus nerve as a routine step in radical lung cancer surgery is an independent risk factor for cough hypersensitivity (CH). However, there are significant disagreements in the thoracic surgery community regarding the strategy for managing the vagus pulmonary plexus, primarily because key clinical issues remain unresolved: How do surgical procedures affect the occurrence and development of CH? And how can these procedures be improved? A large number of published studies have only analyzed "where to cut" while neglecting the surgical issue of "how to cut". Even with a high level of evidence, the conclusions remain contradictory. This is because doctors' preferences and changes in supply conditions can influence the selection of instruments. Differences in the energy of the instruments can lead to varying degrees and scopes of vagus nerve degeneration and collateral damage to the sympathetic pulmonary plexus, while CH is regulated by both the sympathetic and parasympathetic nervous systems. This project intends to explore the correlation between the selection of surgical instruments and the occurrence and development of postoperative CH at the clinical level, providing a reference for optimizing surgical methods and preventing and treating postoperative CH after lung surgery. The specific research objectives are: to clarify the correlation through a randomized controlled trial, comparing the patterns and changes in the occurrence and development of postoperative CH between two groups of patients whose autonomic nerve pulmonary plexus was transected using energy-based instruments versus mechanical methods. Optimize the surgical procedure: Based on the above results, propose a safe, effective, and feasible surgical method to reduce intraoperative damage, prevent postoperative CH, and improve patients' quality of life. Key problems to be solved: How do surgical operations affect the occurrence and development of CH? How can improvements be made? 1. Clinical issues: ① Do energy-based instruments (causing thermal damage, etc.) and mechanical transection (causing physical damage), which lead to varying degrees of vagus nerve injury and collateral sympathetic nerve damage, affect the occurrence and development of postoperative cough hypersensitivity (CH)? ② How to optimize surgical operations to reduce the incidence of postoperative CH and improve patients' quality of life? 2. Correlation mechanisms: How do different instruments and energy modes affect the pathophysiology of nerve injury, degeneration, and repair, and what are the correlation patterns and mechanisms between these and the occurrence and development of CH?

Endotracheal intubation is a standard procedure used to secure the airway during general anesthesia. A key component of the breathing tube is the "cuff," a balloon-like device that is inflated to seal the airway and prevent aspiration. However, if the pressure within this cuff is too high, it can restrict blood flow to the tracheal lining, leading to complications such as postoperative sore throat, hoarseness, and difficulty swallowing (dysphagia). Currently, there are various methods to monitor and adjust this pressure. In many clinical practices, the pressure is adjusted subjectively or checked only once at the beginning of the surgery. These methods may allow pressure to exceed safe limits (typically 20-30 cmH₂O) or fluctuate during the procedure, potentially causing tissue irritation. This randomized controlled trial aims to compare three different methods of assessing and maintaining endotracheal tube cuff pressure to determine which is most effective at reducing postoperative complications. The study focuses on women undergoing elective breast surgery, a group chosen because the surgery typically lasts 1-3 hours and does not involve major changes in head and neck position, allowing for a clear assessment of the cuff pressure methods. Participants will be randomly assigned to one of three groups: * Continuous Monitoring Group: Cuff pressure is monitored continuously using a pressure indicator and maintained within the 20-30 cmH₂O range throughout the surgery. * Manometer Group: Cuff pressure is measured and set to 20-30 cmH₂O using a manual manometer once, immediately after intubation. * Control Group (Minimal Occlusive Volume): The cuff is inflated with the minimum amount of air required to prevent an air leak, without using a pressure gauge. Researchers will assess patients for sore throat, cough, hoarseness, and swallowing difficulties at 0, 1, 12, and 24 hours after surgery to identify the safest and most comfortable method for airway management.

Endotracheal Tube (ETT) is frequently used for GA (general anesthesia) to deliver oxygen and volatile anesthetic agents to the patient and serves as a channel for anesthetic gases. The ETT cuff helps in positive pressure ventilation and maintains an adequate seal between the endotracheal tube and trachea. Prolonged inflation of ETT cuff can cause ischemic changes of tracheal mucosa and other complications like postoperative sore throat (POST), hoarseness of voice, difficulty in swallowing, tracheal wall ulcer, stricture etc. Among these, the occurrence of sore throat after GA ranges from 21 - 65% Hence it important to measure ETT cuff pressure in intubated patients. The reliable and convenient way for this is using an ETT manometer, which is not readily available in most of hospitals in Pakistan.Many studies have focused on incidence of POST. Most of these studies have been done in western population and differences in various ethnicities are well reported . In Pakistan, air is widely used for ETT cuff inflation. If the results depict minimal cuff pressure changes and postoperative side effects with Xylocaine as compared to air, then it can be inferred that cuff pressure does not increase due to N2O when Xylocaine is used, hence, it can be safely used for cuff inflation eliminating the requirement of ETT cuff pressure monitoring and also the ETT cuff manometer, serving as a cost-effective alternative.
NCT05660850

NCT07088224
This observational study aims to identify the risk factors associated with postoperative sore throat (POST) and to develop a clinical prediction model for patients undergoing thyroid surgery under general anesthesia. Despite improvements in surgical and anesthetic techniques, POST remains one of the most common complications following thyroidectomy, with an incidence of up to 80%. POST can significantly impact patient comfort, swallowing function, nutritional intake, and recovery quality, leading to prolonged hospitalization and increased healthcare costs. The etiology of POST is multifactorial, involving intubation-related factors (e.g., endotracheal tube size, cuff pressure), surgery-related factors (e.g., duration of surgery, neck hyperextension), and patient-related factors (e.g., age, sex, smoking history, pre-existing throat symptoms). However, large-scale, systematic studies in the Chinese population remain limited. With the increasing adoption of Enhanced Recovery After Surgery (ERAS) principles, the accurate identification of modifiable risk factors and early prediction of POST risk are essential for targeted preventive strategies and improved perioperative management. Recent advancements in machine learning and statistical modeling allow for the development of personalized, multifactorial risk assessment tools. In this study, clinical data from patients undergoing thyroid surgery at Nanjing First Hospital will be collected and analyzed. The primary goal is to identify key preoperative and intraoperative predictors of POST and to establish a multivariable nomogram-based prediction model. Internal validation using bootstrap methods will be performed to evaluate the model's discrimination, calibration, and clinical utility, ultimately supporting evidence-based interventions to improve postoperative outcomes and patient satisfaction.
NCT07077733
This study aims to compare video laryngoscope (VL), video stylet (VS), and fiberoptic bronchoscope (FOB) in elective endotracheal intubations of patients aged 18 to 65 years, classified as ASA I-II and without predicted difficult airways. The primary endpoints are the incidence of postoperative sore throat and hoarseness, while secondary endpoints include intubation time, first-attempt intubation success, hemodynamic responses, and procedure-related complications. Postoperative sore throat and hoarseness will be assessed at the bedside at the 20th minute and 6th hour following extubation.
NCT06634823
The primary goal of this study is to test the hypothesis that injecting steroid intramuscularly is an effective treatment for unexplained chronic cough. This will be achieved through the design of a prospective, placebo-controlled, single-blind, randomized clinical trial in which one group of patients will undergo a steroid injection into the deltoid muscle and the second group will undergo a placebo injection into the deltoid muscle. Data to determine if a clinically significant difference exists between the outcomes of the two groups will be measured by a dichotomous yes/no response to improvement, the Leicester Cough Questionnaire, and a visual analogue scale for symptom severity. This will provide the answer to the general question of whether or not the intramuscular injections are clinically effective for patients with unexplained chronic cough. Furthermore, any adverse reactions will be thoroughly documented. If this hypothesized treatment is proven effective, this can greatly improve the care of chronic cough patients by allowing for an evidence-based treatment option and a treatment option that may improve access to care. While the superior laryngeal nerve (SLN) injection is typically performed by fellowship trained laryngologists, intramuscular injections could be more widely utilized by general otolaryngologists or providers in other fields of medicine.
NCT07040631
The goal of this clinical trial is to find out whether applying Endotra Gel, a hyaluronic acid-based gel, to the endotracheal tube can help reduce sore throat and hoarseness after surgery. These symptoms are common after general anesthesia when a endotracheal tube is placed into the trachea. They can cause discomfort and affect patient recovery. The main questions this study aims to answer are: * Does Endotra Gel reduce the chance of having a sore throat after surgery? * Does it help improve hoarseness or coughing after surgery? Participants in this study will: * Undergo general anesthesia for breast cancer surgery * Be randomly assigned to one of two groups: * One group will receive Endotra Gel applied to the endotracheal tube before intubation * The other group will have standard care with no gel * Be monitored for sore throat, hoarseness, and coughing right after surgery and on the day after surgery * Answer questions about their symptoms and satisfaction with their recovery The results will help researchers learn whether using Endotra Gel during intubation can improve patient comfort and reduce airway irritation after surgery.
