Atelectasis, defined as the incomplete expansion of the lungs, is a significant concern during anesthesia and surgery, particularly in pediatric laparoscopic procedures. It results from the collapse of small airways, leading to impaired gas exchange and increased postoperative complications. Factors contributing to atelectasis include positive pressure ventilation, which can exacerbate lung collapse, and mechanical challenges posed by pneumoperitoneum and patient positioning.

This research aims to evaluate the effectiveness of two ventilation strategies—driving pressure-guided optimum PEEP versus fixed PEEP—in preventing atelectasis in pediatric laparoscopic surgeries. Driving pressure-guided ventilation optimizes lung recruitment and minimizes overdistention by adjusting ventilator settings based on driving pressure, which has been linked to improved lung compliance and reduced risk of atelectasis.

The study acknowledges existing literature indicating that lung-protective ventilation strategies, such as low tidal volume and PEEP application, are crucial in mitigating ventilator-induced lung injury (VILI). However, driving pressure has emerged as a critical factor in patient outcomes, with high driving pressures correlating with increased mortality.

A review of literature highlights the physiological challenges in pediatric patients, including higher oxygen consumption and lower functional residual capacity, which increase the risk of hypoxemia. Several studies have shown that appropriate PEEP levels improve oxygenation and reduce atelectasis during laparoscopic surgery.

This prospective randomized double-blind study seeks to provide insights into the optimal ventilation strategy for minimizing atelectasis and improving respiratory outcomes in pediatric patients. By comparing driving pressure-guided PEEP and fixed PEEP, the research aims to enhance clinical practices in pediatric anesthesia and surgery, ultimately improving patient outcomes and reducing hospital stays.
