2.5. Lung Ultrasonography

LUNG
Lung ultrasonography was performed with a Mindray M5 Mobile TrolleyThe thorax was divided into 12 quadrants according to the anterior and posterior axillary line in both the right and left lung areas; anterior, lateral, and posterior zones were identified, and the upper and lower regions (R1, R2 … R6; L1, L2 … L3) of these zones were also visualized. (During laparoscopic cholecystectomy procedures, patients are placed in the Trendelenburg position in order to enhance surgical vision. However, as the surgical area is located in the upper right quadrant, the most critical anatomical area for surgical manipulation is the area under the right diaphragm, which fits under the right lung. For these reasons, we sought to conduct a detailed analysis of the LUS score in each region.
