A novel method using a single lumen tube and extraluminal bronchial blocker for one-lung ventilation in severe tracheal stenosis: a case report

: Double-lumen tubes (DLT) and bronchial blockers (BB) are usually used to functionally isolate the lungs during thoracic surgery. However, for patients with tracheal stenosis, management of one lung ventilation (OLV) in anesthesia is still full challenges due mismatching between trachea lumen tube diameter. In past, a small single-lumen (SLT) combined an endobronchial pediatric BB or extraluminal detached uninvent obtained successful OLV stenosis. Additionally, nonintubated surgical pneumothorax may work. We first report interesting case 65-year-old man history upper left lobe nodule tracheotomies. A chest computed tomographic (CT) scan showed middle was severely narrowed. minor SLT acquired optimal collapse lung. He accepted video-assisted thoracoscopic lobectomy under general anesthesia. After both were removed, patient did not present dyspnea airway injury. The recovered well discharged from hospital week after This method, BB, convenient sputum suction fiber optic bronchoscope examination, moreover, it option severe stenosis cases.
