简要总结
In thoracic surgery, one-lung ventilation using a double-lumen tube (DLT) is often performed to protect dependent lung and provide comfortable surgical conditions. However, serious complications and adverse events can be encountered during DLT placement. One of the most important steps to avoid these drawbacks is to choose the appropriate size of DLT. The width of the trachea can be measured by using different imaging methods such as computed tomography (CT) and ultrasonography (US) to predict the appropriate DLT size. CT can also contribute to the proper placement of DLT by giving us the length of the trachea and main bronchi. In this study, we hypothesized that the size of the DLT can be determined more accurately by measuring the trachea diameter by using US and CT before DLT intubation. At the same time, we aimed to determine whether the evaluation of tracheobronchial anatomy with CT would contribute to the placement of DLT at a more appropriate level.

结局指标
主要结局
The measurement of the trachea diameter with ultrasound determines the size of the double-lumen tube to be used.
时间窗: 1 hour
After measuring the diameter of the trachea with ultrasound, the doctor will determine the double-lumen tube to be used according to the ultrasound measurement. Another experienced anesthesiologist, unaware of this result, will insert the double-lumen tube that he has determined with the conventional method.
The measurement of the trachea diameter by computerized tomography determines the size of the double-lumen tube is used.
