The safety margin of ETT cuff pressure is between 20-30 cmH2O. Inadequately inflated cuff (\\\u003C20 cmH2O) may cause secretions in the mouth, foreign bodies, bleeding due to surgery to escape into the trachea and\u002For air leakage. As a result of air leakage, the effect of mechanical ventilation decreases, end-tidal CO2 measurement cannot be performed accurately, and inhalation anaesthetics leak into the operating room. An overinflated cuff (\\>30 cmH2O) may affect tracheal mucosa blood flow. This may result in tracheal stenosis, tracheoesophageal fistula or tracheal rupture. There may be significant changes in cuff pressure during endotracheal intubation because cuff pressure can be affected by changes in head and neck position. Due to all these situations, controlling ETT cuff pressure is very important for patient health and safety.\n\nFor ETT cuff pressure control; manual palpation of the pilot balloon, listening for the disappearance of an audible air leak, inflating the cuff with minimal occlusive pressure to a peak inflation pressure of 20-22 cmH2O during positive pressure ventilation, inflating the cuff until the airway is closed by maintaining a continuous positive airway pressure of 20 cmH2O, or cuff manometers are commonly used applications. Although cuff manometers can be used to guide the monitoring of cuff pressure, their use and availability is not mandatory in many institutions around the world (due to the large number of anaesthetic areas, it is not possible to have a manometer everywhere). Therefore, in anaesthetic practice, cuff pressure is monitored manually or using a manometer at regular intervals during the operation.\n\nAim\u002FHypothesis:\n\nH0: Endotracheal tube cuff pressure does not change with hyperextension position given to the neck during adenoidectomy, tonsillectomy or adenotonsillectomy surgery.\n\nH1: Endotracheal tube cuff pressure changes with hyperextension position given to the neck during adenoidectomy, tonsillectomy or adenotonsillectomy surgery.\n\nMaterial-Methods: The study will include patients between the ages of 2-18 years who will undergo adenoidectomy, tonsillectomy or adenotonsillectomy after obtaining informed consent from their parents. Routine practice will be followed for induction and maintenance of anaesthesia. Patients monitored in the operating room according to the standard American Society of Anesthesiologists (ASA) protocol will be orotracheally intubated with an ETT of appropriate internal diameter after induction of anaesthesia by the anaesthesiologist responsible for the patient. After the tube placement of the intubated patients is confirmed by the responsible anaesthesiologist, the ETT cuff will be measured and recorded by the responsible investigator with a cuff manometer (VBM Medizintechnik, GmbH, Germany) while the head and neck are in the neutral position (T0). When the patients are given the head-neck hyperextension position in which the surgery will be performed by the surgical team responsible for the patient's surgery, the pressure measurements will be repeated by the responsible investigator (T1). At the end of the operation, when the head and neck are returned to the neutral position, the tubular cuff pressure will be measured by the responsible investigator for the last time (T2).\n\nPatients between 2-18 years of age who underwent adenoidectomy, tonsillectomy or adenotonsillectomy surgery will be included in the study. Patients with head and neck mobility restriction, patients who have had neck surgery before, and patients with body mass index (BMI) \\> 35 kg\u002Fm2 will be excluded from the study.",[86,87,88,28],"Endotracheal Cuff","Adenoidectomy Surgery","Tonsillectomy with or Without Adenoidectomy","RECRUITING","2025-02-05",{"date":92,"type":36},"2025-02-07",{"date":94,"type":36},"2025-01-06",{"date":96,"type":23},"2025-12-31",{"name":98,"class":99},"Ankara Ataturk Sanatorium Training and Research Hospital","OTHER_GOV"]
