About this trial
The primary objective of this study is to evaluate and compare the incidence and severity of intraoperative pulmonary atelectasis, measured by Lung Ultrasound Score (LUS) and EIT (Electrical Impedance Tomography), between two different modes of mechanical ventilation: Volume Control Ventilation (VCV) and Pressure Regulated Volume Control (PRVC/PCV-VG)
Eligibility criteria
Qualifiers
Patients requiring intraoperative mechanical ventilation via endotracheal intubation
Written informed consent obtained from parents or legal guardians. For children capable of understanding, assent will also be obtained based on age and cognitive ability.
ASA (American Society of Anesthesiologists) physical status I-II
Disqualifiers
Patients with significant pre-existing lung disease (e.g., cystic fibrosis, severe bronchopulmonary dysplasia, severe uncontrolled asthma, neuromuscular disease with respiratory compromise).
Patients with complex congenital heart disease or significant hemodynamic instability.
Patients undergoing thoracic surgery or procedures that could significantly alter lung mechanics (e.g., pre-existing pneumothorax).
Refusal of parents/guardians or patient to participate in the study.
