Lung Ultrasound Score (LUS) Change in Robotic and Laparoscopic Urologic Surgeries

In the researchers' words

Robotic and laparoscopic surgeries are tend to cause lung atelectasis due to the insufflation of CO2 into abdomen. However, ultrasonographic measurement for this phenomenon and its clinical use is not well investigated. In this particular study, It is aimed to observe lung ultrasound score (LUS) changes in robotic and laparoscopic supine position surgeries such as prostatectomies and cystectomies. LUS is a pragmatic measurement method that calculates the degree of atelectasis and consolidation in the lungs. Both hemithoraxes are separated into 3 different segments with vertical lines (one between the parasternal line and anterior axillary line, one between the anterior and posterior axillary line, and one posterior to the posterior axillary line). These vertical segments are also divided into two with an horizontal line on the nipple. Lung ultrasonography is applied in all 12 zones for both lungs in the intercostal regions and a scoring system is used. Accordingly, pure A lines (transverse frequent lines) reflects normal lung tissue with no consolidation and scored as zero points (Also named "A"). If less than 4 B lines (vertical lines reflecting some degree of consolidation) is observed, it refers to 1 point (named "B1"). 4 or more B lines refers to 2 points (B2), and if wide and coalesced B lines or patchy pleural line is observed that refers to 3 points (C).
