What this trial studies

This study evaluates the frequency of pulmonary atelectasis in children undergoing general anesthesia by comparing two different ventilation modes: volume controlled ventilation (VCV) and pressure controlled ventilation (PCV). Using traditional and modified lung ultrasonography scoring systems, the study aims to assess lung function and the presence of atelectasis during surgery. The evaluation is performed while patients are in a supine position, dividing the thorax into quadrants for detailed ultrasound analysis. The goal is to determine which ventilation mode is more effective in preventing lung collapse in pediatric patients.

Who should consider this trial

Good fit: Ideal candidates are children aged 2 to 10 years who are undergoing elective surgery with general anesthesia and have an ASA score of I-II.

Not a fit: Patients with known lung diseases, recent pulmonary infections, or certain surgical histories may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved ventilation strategies that reduce the risk of lung collapse in children during surgery.

How similar studies have performed: While there have been studies on ventilation modes, this specific comparison in pediatric anesthesia using lung ultrasound is relatively novel.
