Postoperative Sore Throat, Cough, Hoarseness

Abstract Objective: The aim of this study is to compare two different ways of adjusting the air-filled cushion (cuff) of the breathing tube used during general anesthesia in children undergoing laparoscopic appendectomy (closed surgery for appendicitis). The goal is to see if maintaining the pressure in this cushion within a safe, specific range (15-18 mmHg) helps prevent or reduce sore throat, hoarseness, and discomfort, which are common postoperative complications in children. Study Design: This is a prospective, randomized, controlled study. Sixty children aged 6 to 18 years scheduled for laparoscopic appendectomy will be included. Participants will be randomly assigned to two equal groups: Group A (Control Group): Breathing tube cuff pressure is adjusted using the standard "feeling" (finger palpation) method common in routine practice. Group B (Intervention Group): Breathing tube cuff pressure is measured throughout the surgery using a medical pressure sensor (manometer) and maintained within a safe range (15-18 mmHg). Research Questions: Does actively monitoring airway pressure reduce the number of children experiencing postoperative sore throat? Does this method reduce the severity of sore throat, cough, hoarseness, or other respiratory discomfort compared to the standard method? What will happen? During surgery, respiratory and heart rate measurements will be recorded every 15 minutes for all participants. After surgery, researchers will visit participants (and their parents) at 2, 6, and 24 hours postoperatively to assess the presence of sore throat, discomfort, or hoarseness. No additional medications or invasive procedures will be used for this study; only how we manage airway pressure will be compared.

This randomized clinical trial aims to evaluate the effectiveness of two medications-hydrocortisone ointment and lidocaine solution-applied to the endotracheal tube in reducing postoperative throat pain, hoarseness, and cough following thyroid or parathyroid surgery with neuromonitoring. A total of 764 adult patients undergoing elective neck surgery at Saint-Petersburg State University Hospital will be enrolled and randomly assigned to receive either a hydrocortisone-coated or lidocaine-coated endotracheal tube. Outcomes will be assessed upon awakening from anesthesia, at 24 hours, and again at 3 days postoperatively. The findings may contribute to improving postoperative comfort and recovery for patients undergoing similar surgical procedures.

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.
