1. Schematic diagram portraying the use of the fiber-optic bronchoscope to insert a left-side DLT. A. The DLT can be put into the trachea in a conventional manner, and both lungs can be ventilated by both lumens. The fiber-optic bronchoscope may be inserted into the left lumen of the DLT through a self-sealing diaphragm in the elbow connector to the left lumen; this allows continued positive pressure ventilation of both lungs through the right lumen without creating a leak. After the fiber-optic bronchoscope has been passed into the left main stem bronchus (B), it is used as a stylet for the after-coming left lumen (C). The fiber-optic bronchoscope is then withdrawn. Final precise positioning of the DLT is performed with the fiber-optic bronchoscope in the right lumen. [Reproduced with permission from Benumof JL, ed. Anesthesia for Thoracic Surgery, 2nd ed.
