简要总结
This is a prospective, randomized, single-blinded controlled trial designed to compare CT-guided versus conventional methods for selecting double-lumen tube (DLT) size in patients undergoing thoracic surgery requiring one-lung ventilation
详细描述
This is a prospective, randomized, single-blinded controlled trial designed to compare CT-guided versus conventional methods for selecting double-lumen tube (DLT) size in patients undergoing thoracic surgery requiring one-lung ventilation. The study aims to evaluate whether preoperative computed tomography (CT)-based bronchial diameter measurement improves the accuracy of initial DLT size selection compared with conventional selection based on demographic parameters.
Eligible patients will be randomly assigned in a 1:1 ratio to either the CT-guided group or the conventional group.

盲法说明
The anesthesiologist performing the intubation will remain blinded to group allocation and will not be informed whether the selected DLT size was based on CT measurements or conventional demographic-based criteria.

研究组 & 干预措施
Conventional Group
DLT size will be selected using standard clinical criteria based on patient demographics, according to institutional standard tables.
干预措施: Conventional Group (Control) (Other)
CT-Guided Group
Participants will undergo preoperative CT measurement of the bronchial diameter 10 mm distal to the carina. DLT size will be selected using manufacturer-recommended correlation charts based on CT measurements.
