Introduction
Recent advances in surgical techniques for thoracic, cardiac, or esophageal surgery have led to an increased use of lung separation techniques. Currently a double-lumen endotracheal tube (DLT) or bronchial blockers are used to achieve one-lung ventilation (OLV). The independent blockers are used in general, in combination with a single-lumen endotracheal tube as with the wire-guided endobronchial blocker Arndt® blocker, the Cohen® tip-deflecting endobronchial blocker or the Fuji Uniblocker®.
There are a number of recognized indications for OLV. In practice, the most common indications for lung separation are: 1) for surgical exposure (lung separation), 2) for prevention of contamination to the contralateral lung from bleeding, pus or saline lavage (lung isolation), and 3) during differential lung ventilation for continuity of airway gas exchange such as with bronchopleural fistula. Table I describes the common indications for lung isolation with a DLT or an independent bronchial blocker.
