Lung Ultrasound, Cholecystectomy, Atelectasis

he patients included in the study were divided into 2 groups. Among the patients who were going to be operated, 5 PEEP were applied to Group I (n=30) cases, and 10 PEEP to Group II (n=30) cases during ventilation with anesthesia device. All patients were evaluated by transthoracic lung ultrasonography before anesthetic induction, after tracheal intubation, after pneumoperitoneum, and 15 minutes after recovery from anesthesia. According to the lung USG protocol, a total of 6 regions, including 2 quadrants of each hemi-thorax anterior wall, 2 right and left lateral walls, and 2 quadrants of the posterior wall, a total of 12 regions in each patient were scanned, and the images were evaluated. According to the modified lung USG scoring system, each region was scored between 0-3 consistent with the degree of atelectasis
