Lung Ultrasound Score (LUS) Change in Robotic & Laparoscopic Urologic

Status Recruiting

Clinical Trial Summary

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). All evaluations will be made in supine position. In this trial, LUS will be applied in three different time points: T1: 5 minutes after orotracheal intubation T2: At the end of surgery, before extubation (under deep anesthetic state) T3: 30 minutes after extubation, in postanesthesia care unit During the surgery and the postoperative care period standart monitorization and mechanical ventilation data will be gathered. Also intraoperative and postoperative blood gas analysis will be obtained to observe oxygenation changes. This study is planned as a prospective observational study and our hypothesis is that LUS scores would be lower in acute postoperative period with robotic and laparoscopic surgeries. Therefore primary outcome is the numeric change in T3 and T1. Secondarily, LUS scores will be evaluated between robotic group and laparoscopic group patients for all time points.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
