Figure 49-26 The Arndt bronchial blocker kit includes a wire-guided endobronchial blocker and a multiport airway adapter. After placement of an endotracheal tube, the Arndt bronchial blocker is placed through the blocker port of the airway adapter; the fiberoptic bronchoscope is then placed through the wire loop, into the trachea, and positioned within the bronchus of choice. The fiberoptic bronchoscope has to be advanced far enough so that the Arndt blocker will enter the bronchus while it is being advanced. Once the deflated cuff is below the entrance of the bronchus, the fiberoptic bronchoscope is withdrawn, and the cuff is fully inflated with air (using the just-seal approach). After the patient is turned to the lateral decubitus position, bronchoscopic confirmation is necessary to ensure that the cuff of the Arndt blocker is still properly positioned.
