Outcome Measures
Primary Outcomes (1)
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
the correct placement of a double-lumen tube (DLT) on the first attempt, achieving optimal tracheobronchial position and effective lung isolation as confirmed by fiberoptic bronchoscopy, without the need for tube exchange or repositioning.
During the intraoperative period (at first attempt of double-lumen tube placement)
Secondary Outcomes (5)
Incidence of DLT replacement
Intraoperative period (from initial DLT placement until end of surgery)
Time required for successful intubation
Intraoperative period (from DLT insertion to confirmed successful placement)
Frequency of intraoperative hypoxia and peak airway pressure fluctuations
Intraoperative period (from DLT insertion to confirmed successful placement)
Blinded assessment of surgeon satisfaction (lung isolation quality)
At the end of surgery (intraoperative assessment)
Post-operative sore throat or airway trauma
24 hours post-extubation
Study Arms (2)
CT-Guided Group
EXPERIMENTALParticipants 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.
Conventional Group
ACTIVE COMPARATORDLT size will be selected using standard clinical criteria based on patient demographics, according to institutional standard tables.
Interventions
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.
DLT size will be selected using standard clinical criteria based on patient demographics, including sex, height, and weight, according to institutional standard tables.
Eligibility Criteria
You may qualify if:
- Adult patients (≥18 years) scheduled for elective thoracic surgery requiring one-lung ventilation.
- Availability of preoperative thoracic CT imaging.
- Procedures requiring placement of a left-sided DLT.
- Patient who has a normal pulmonary function test.
You may not qualify if:
- 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
