Evaluation of the Effects of Different Ventilation Modes Used During Anesthesia Awakening on the Frequency of Postoperative Atelectasis

The patients included in the study underwent lung imaging with lung ultrasound score twice, in the preoperative preparation room and in the postoperative recovery unit.Both lungs were determined as anterior and posterior axillary lines as anatomical markers and divided into a total of 12 regions, 4 in the anterior thoracic wall, 4 in the lateral wall, and 4 in the posterior region. In our study, we will use the modified LUS scoring, which has been shown to be more sensitive in the diagnosis of postoperative atelectasis in the recovery unit, based on existing literature reviews. The degree of the atelectasis will be determined according to do modified lung ultrasound score. Lung ultrasound score imaging of all patients was performed by the same anesthesiologist.
