Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators evaluate the effect of postural change on the bronchial cuff pressure (BCP) of double-lumen endotracheal tube (DLT) in patients undergoing thoracic surgery, by observing the pressure of the bronchial cuff before and after lateral decubitus positioning.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is essential to maintain proper cuff pressure in the endotracheal tube (ETT) when placing the ETT in the trachea in patients undergoing general anesthesia. Most of the literature recommend maintaining a pressure of 20-30 cmH2O to prevent cuff-related complications such as micro-aspiration or airway trauma. Proper pressure is also important for DLTs used in thoracic surgery. Furthermore, the cuff pressure of the ETT can change during the patient's positional changes. All things considered, we hypothesized that the change from supine to lateral decubitus position, which is essential for thoracic surgery would affect the BCP of the DLT.

Interventions

Learn about the drugs, procedures, or behavioral strategies being tested and how they are applied within this trial.

Lateral decubitus positioning

After the DLT intubation, the patient is placed in lateral decubitus position

Intervention Type BEHAVIORAL

Cuff-manometer

The pressure of the bronchial cuff should be measured with cuff-manometer in supine position, and then measurement should be repeated after lateral positioning.
