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.

ABSTRACT:

Introduction

Postoperative sore throat and hoarseness are common complications following lung isolation with double-lumen tubes (DLTs) in video-assisted thoracoscopic surgery (VATS). Laryngeal mask airway (LMA) combined with a visual bronchial blocker (VBB) may reduce airway trauma while maintaining effective lung isolation.

Methods and analysis

This is a prospective, randomised, controlled, single-blind, multicentre clinical trial conducted at three major thoracic surgery centres in Shanghai, China. A total of 270 patients aged ≥18 years scheduled for elective VATS anatomical lung resection will be randomly allocated 1:1 to either the VBB group (n=135) using LMA combined with VBB or the DLT group (n=135) using conventional DLT (see Consolidated Standards of Reporting Trials
