Official title

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

Overview

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

Detailed description

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.

Interventions

  • Other CT-Guided Group (Intervention)
    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.
  • Other Conventional Group (Control)
    DLT size will be selected using standard clinical criteria based on patient demographics, including sex, height, and weight, according to institutional standard tables.

Primary outcome measures

  • Successful selection of the correct DLT size on the first attempt (defined as optimal position and lung isolation without the need for tube exchange) using fiberoptic scope [Time frame: During the intraoperative period (at first attempt of double-lumen tube placement)]
Secondary outcome measures (5)
  • Incidence of DLT replacement [Time frame: Intraoperative period (from initial DLT placement until end of surgery)]
  • Time required for successful intubation [Time frame: Intraoperative period (from DLT insertion to confirmed successful placement)]
  • Frequency of intraoperative hypoxia and peak airway pressure fluctuations [Time frame: Intraoperative period (from DLT insertion to confirmed successful placement)]
  • Blinded assessment of surgeon satisfaction (lung isolation quality) [Time frame: At the end of surgery (intraoperative assessment)]
  • Post-operative sore throat or airway trauma [Time frame: 24 hours post-extubation]

Eligibility criteria

Inclusion criteria

  • Adult patients (≥18 years) scheduled for elective thoracic surgery requiring one-lung ventilation.

  • Patient who has a normal pulmonary function test.

Exclusion criteria

  • Previous tracheal surgery
  • Patient with difficult airway whom need bronchial blocker.
  • Emergency thoracic procedures.
  • Incomplete intraoperative or imaging data.
  • Patient with severe obstruction or restriction.
  • Pediatric patient
