CT-Guided vs Conventional DLT Sizing in Thoracic Surgery

CT-Guided Versus Traditional Selection of Double-Lumen Tube Size for One-Lung Ventilation in Thoracic Surgery: A Prospective Study

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

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.

Inclusion Criteria:

1. Adult patients (≥18 years) scheduled for elective thoracic surgery requiring one-lung ventilation.
2. Availability of preoperative thoracic CT imaging.
3. Procedures requiring placement of a left-sided DLT.
4. Patient who has a normal pulmonary function test.

Exclusion Criteria:

1. Previous tracheal surgery
2. Patient with difficult airway whom need bronchial blocker.
3. Emergency thoracic procedures.
4. Incomplete intraoperative or imaging data.
5. Patient with severe obstruction or restriction.
6. Pediatric patient
