Airway and Respiratory Devices
Other Devices
Other supraglottic airway devices include laryngeal tube or twin-lumen airways (eg, Combitube, King laryngeal tube). These devices use 2 balloons to create a seal above and below the larynx and have ventilation ports overlying the laryngeal inlet (which is between the balloons). As with laryngeal mask airways, prolonged placement and balloon overinflation can cause tongue edema. These can be used as alternative airway after failed intubation attempts with an endotracheal tube. (see How To Insert an Esophageal-Tracheal Double Lumen Tube (Combitube) or a King Laryngeal Tube ).
