Can Imaging Techniques Contribute to the Proper Insertion of Double-lumen Tubes?

Completed

• Conditions: Double-Lumen Tube; Computed Tomography; Ultrasonography

• Registration Number: NCT05133401
• Lead Sponsor: Atatürk Chest Diseases and Chest Surgery Training and Research Hospital

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
The measurement of the trachea diameter with ultrasound determines the size of the double-lumen tube to be used.	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.	1 hour	After measuring the diameter of the trachea with computerized tomography, the doctor will determine the double-lumen tube to be used according to the computerized tomography 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 tracheal and main bronchi length and main bronchi diameter by computerized tomography in determining the size of the double-lumen tube and proper positioning of the double-lumen tube.	1 hour	The correlation of predicted and used DLT size. In addition, the correlation between DLT malposition rate and trachea and main bronchi length and main bronchi diameter measured by imaging methods.

Secondary Outcome Measures

Name	Time	Method
Complications related to double-lumen tube intubation	1 day	Evaluation of trauma, bleeding, sore throat and hoarseness in the airways due to double-lumen tube intubation.
