BACKGROUND: One-lung ventilation utilizing a double-lumen endotracheal tube may be technically difficult or inappropriate in morbidly obese or critically ill patients. In patients requiring awake fiberoptic intubation, double-lumen tube placement may be impossible. Wire-guided endobronchial blockade through a conventional endotracheal tube is a new alternative for these patients. METHODS: A 44-year-old, 133 kg female patient was scheduled to undergo a thoracotomy for transthoracic fundoplication. A wire-guided endobronchial blocker (WEB) was placed following rapid-sequence induction and intubation with an 8.0 OD single-lumen endotracheal tube with the aid of a pediatric bronchoscope. RESULTS: The WEB, using a guiding loop, was placed with ease and allowed effective one-lung ventilation. CONCLUSION: The WEB system allows one-lung ventilation to be achieved with a conventional endotracheal tube. The need for reintubation at the end of surgery is eliminated and endotracheal tube cross-sectional area is conserved.
