This type of surgery is performed through a small incision in the chest, and good lung collapse helps the surgeon see and work safely. The main questions it aims to answer are\n\n1. Does brief bronchial suction improve the quality of lung collapse 1 minute after chest cavity is opened?\n2. Does brief bronchial suction help reach satisfactory lung collapse faster?\n\nResearchers will compare patients who receive brief bronchial suction and those who do not. This is to see if suction improves and fastens lung collapse, reduce the need for additional steps if lung is not adequately collapsed, affect inflammation, oxygenation, postoperative pulmonary complications, operative time, and the duration of one-lung ventilation. Participants will\n\n1. Undergo UVATS under general anesthesia\n2. Have a double-lumen breathing tube placed as part of the standard anesthetic care\n3. Be randomly assigned to either receive bronchial suction for one minute or receive no bronchial suction\n4. Have the surgical team assess the quality of lung collapse at different time points\n5. Have blood samples taken for interleukin-6, a marker related to inflammation, once during and once after surgery. These samples are collected through a small tube in a vein that is placed as a standard anesthetic care while the participant is under general anesthesia. No extra puncture is required for blood collection.\n6.

If the DLT is not placed in the proper size and depth, it may result in repeated intubation attempts, airway and dental trauma, failed lung isolation, tube dislodgement, and various unwanted events such as hypoxemia.\n\nThe first and most common method for correct placement of a DLT is the conventional technique, blindly advanced into the left main bronchus, and then confirmed with fiberoptic bronchoscopy (FOB). In this method, the depth at which the tube should be left before performing FOB is left to the clinician's experience. Generally, the DLT is advanced in the trachea until a slight resistance is felt. This may lead to excessive advancement of the DLT into the left main bronchus or premature resistance due to the tube tip touching the carina, causing the clinician to stop before entering the left main bronchus. Therefore, just as selecting the correct size of the DLT is crucial, correctly estimating the appropriate depth is also of great importance. For this reason, different formulas have been proposed in the literature, and new formulas are still being investigated.\n\nThe patient's gender and height are determinant in selecting the appropriate size of the DLT. However, studies in the literature indicate that the accuracy of these formulas may be limited in Asian populations. Therefore, it is important to evaluate the applicability of these formulas in different populations and, if necessary, develop new formulas. In the Turkish population as well, verifying the accuracy of these formulas for determining the proper size and depth of DLT-and if needed, developing new recommendations and formulas-holds clinical importance.\n\nIn this study, conducted at Ankara Atatürk Sanatorium Training and Research Hospital, the aim is to evaluate the accuracy of six different formulas available in the literature for predicting DLT depth in patients undergoing thoracic surgery. Additionally, the correlations between DLT depth and demographic parameters as well as external airway measurements (mouth opening, sternomental distance, thyromental distance, distance between the mentum and manubrio-sternal angle, distance between tragus and manubrio-sternal angle, distance between sternal angle and xiphoid process) will be analyzed. Furthermore, challenges during DLT application, malposition rates and types, and complications will be assessed.\n\nThe primary objective of this study is to evaluate, in patients undergoing thoracic surgery at Ankara Atatürk Sanatorium Training and Research Hospital, how accurate and applicable six different formulas defined in the literature are for predicting the placement depth of the DLT. If the existing formulas are insufficient, the aim is to develop a new formula.",[31,68,29],"One-lung Ventilation (OLV)",[70,71,72,73,74,29],"Double-Lumen Tube","Fiberoptic Bronchoscopy","Airway Measurements","One-Lung Ventilation","Tube Placement Depth","RECRUITING","2025-09-29",{"date":78,"type":46},"2025-10-02",{"date":76,"type":46},{"date":81,"type":21},"2026-03-30",{"name":83,"class":84},"Ankara Ataturk Sanatorium Training and Research Hospital","OTHER_GOV","Double Lumen Tube"]
