Double-lumen endobronchial tube PA34R

With low-pressure polyurethane tracheal and bronchial cuffs With blue color-coded bronchial cuff, bronchial proximal lumen, and bronchial pilot balloon With x-ray opaque carinal hook Double-lumen tubes (DLTs) are the most commonly used tubes to provide independent ventilation for each lung. One-lung ventilation (OLV) or lung isolation is the mechanical and functional separation of the 2 lungs to allow selective ventilation of only one lung. The other lung that is not being ventilated passively deflates or is displaced by the surgeon to facilitate surgical exposure for non-cardiac operations in the chest such as thoracic, esophageal, aortic and spine procedures. This activity reviews the use of the DLT, its indications, contraindications, and complications in thoracic surgery. USES Anatomical lung separation (this isolates a diseased lung from contaminating the non-diseased lung) ·Massive hemoptysis (protect normal lung from blood) ·Whole lung lavage for pulmonary alveolar proteinosis (lavage worst lung first) ·Copious secretions (e.g. bronchiectasis, lung abscess) (protect normal lung from pus) Physiological lung separation (ventilates each lung as an independent unit) ·Unilateral parenchymal injury: — Aspiration — Pulmonary contusion — Pneumonia — Unilateral pulmonary edema ·Single lung transplant (post operative complications) — e.g. COPD patient with lung transplant requiring different ventilation strategies for each lung
