• The visual bronchial blocker integrates a micro-camera at the distal tip, providing real-time forward visualisation and eliminating the need for a separate fibreoptic bronchoscope. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
• The VBB is advanced 15–20 mm beyond the carina into the target main bronchus under direct visual guidance. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
• For right-sided VBB placement, correct positioning is additionally verified by visual confirmation of the right upper lobe orifice. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
• The VBB features adjustable angulation for easier passage through the vocal cords, an integrated blocking balloon, and continuous intraoperative monitoring capability. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
• High-quality comparative evidence of the VBB versus DLT for VATS is absent. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
• The VBB has a larger outer diameter (3.4 mm) than conventional bronchial blockers because of its integrated camera. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
• Conventional bronchial blockers present practical challenges including difficult positioning, poor malleability, and dependence on a separate fibreoptic bronchoscope. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
• The mechanical stimulus of the larger VBB traversing the glottis could still contribute to postoperative symptoms despite its softer shaft. — Laryngeal mask airway combined with visual bronchial blocker versus double-lumen tube for lung isolation in video-assisted thoracoscopic surgery: a protocol for a multicentre randomised controlled trial
