AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults having planned thoracoscopic (keyhole chest) surgery who need a right-sided double-lumen breathing tube to isolate one lung.
- Age
- 18 years or older
- Sex
- All sexes can join
- Disease stage
- Planned (elective) thoracoscopic surgery that needs lung isolation with a right-sided double-lumen tube; ASA physical status I-III

- Original description
Right-sided double-lumen tubes are used for lung isolation during thoracoscopic surgery but can be difficult to position because of right bronchial anatomy. This multicenter randomized controlled trial will compare a continuous video-guided right-sided double-lumen tube with a conventional right-sided double-lumen tube in adult patients undergoing thoracoscopic surgery requiring right-sided lung isolation. The primary objective is to determine whether continuous video guidance increases the rate of successful initial right-sided double-lumen tube positioning. Secondary outcomes include positioning time, clinically relevant intraoperative tube displacement, rescue fiberoptic bronchoscopy, lung collapse quality, hypoxemia during one-lung ventilation, and airway-related complications.Read full original descriptionShow less
Continuous Video-guided Versus Conventional Right-sided Double-lumen Tube Placement for Lung Isolation in Thoracoscopic Surgery: A Multicenter Randomized Controlled Trial
Right-sided double-lumen tubes are used for lung isolation during thoracoscopic surgery but can be difficult to position because of right bronchial anatomy. This multicenter randomized controlled trial will compare a continuous video-guided right-sided double-lumen tube with a conventional right-sided double-lumen tube in adult patients undergoing thoracoscopic surgery requiring right-sided lung isolation. The primary objective is to determine whether continuous video guidance increases the rate of successful initial right-sided double-lumen tube positioning. Secondary outcomes include positioning time, clinically relevant intraoperative tube displacement, rescue fiberoptic bronchoscopy, lung collapse quality, hypoxemia during one-lung ventilation, and airway-related complications.
Inclusion: Adults aged 18 years or older; American Society of Anesthesiologists (ASA) physical status I-III; Patients scheduled for elective thoracoscopic surgery requiring lung isolation with a right-sided double-lumen tube; Patients who provide written informed consent.
Exclusion: Emergency surgery; Thoracic surgery within 4 weeks before enrollment, recent respiratory infection, or known or suspected pulmonary tuberculosis; Concurrent participation in another interventional clinical trial that may affect the study outcomes; Contraindications to placement of a right-sided double-lumen tube, including right main bronchial lesions that preclude its use; Known tracheobronchial anatomical abnormalities; Known or anticipated difficult airway; Requirement for rapid sequence induction; Severe respiratory instability.
