Effect of Endotracheal Tube Cuff Pressure Management on Postoperative Sore Throat in Pediatric Laparoscopic Appendectomy
Sponsor: Ankara Etlik City Hospital
Summary
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.

Conditions
Interventions
Pressure Transducer
In this group of patients, endotracheal tube cuff pressure was continuously monitored using a pressure transducer from an invasive arterial pressure measurement set and maintained within a safe range (15-18 mmHg).
Traditional Palpation Method
The endotracheal tube cuff pressure was adjusted by the anesthesiologist using the subjective manual palpation technique, where the pressure in the cuff was estimated by manually squeezing the pilot balloon. No external monitoring device was used in this group, reflecting the conventional clinical practice.
