Video-guided right-sided double-lumen tube for one-lung ventilation in thoracoscopic surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicentre randomized trial compares a video-guided right-sided double-lumen tube with an ordinary right-sided tube in adults undergoing elective thoracoscopic surgery needing one-lung ventilation. Participants are assigned 1:1 to receive either tube, with final position confirmed by fibreoptic bronchoscopy in both groups. The video-guided tube provides continuous airway visualization during placement and surgery, while the conventional tube relies on standard technique. Primary outcome is successful initial tube placement; secondary outcomes include airway obstruction, tube displacement, hypoxemia, and need for rescue bronchoscopy. The study aims to determine if real-time visualization improves accuracy and safety of lung isolation in this setting.

Why it matters

Who can join: the full rules

\*\*Inclusion Criteria:\*\*

1. Adults aged 18 years or older.
2. American Society of Anesthesiologists physical status I-III.
3. Scheduled for elective thoracoscopic surgery requiring one-lung ventilation with a right-sided double-lumen tube.
4. Able to provide written informed consent.

\*\*Exclusion Criteria:\*\*

1. Contraindication to placement of a right-sided double-lumen tube, including a lesion involving the right main bronchus that precludes its use.
2. Known tracheobronchial anatomical abnormality that may interfere with right-sided double-lumen tube placement or lung isolation.
3. Known or anticipated difficult airway.
4. Requirement for rapid-sequence induction.
5. Emergency surgery.
6. Severe respiratory instability that, in the investigator's judgement, makes participation unsafe.
7. Concurrent participation in another interventional clinical trial that could interfere with the present study.
