The Esophageal-Tracheal Combitube

The ETC is an easily inserted, double-lumen/double-balloon supraglottic airway device. The major indication of the ETC is as a back-up device for airway management. It is an excellent option for rescue ventilation in both in- and out-of-the-hospital environments and in situations of difficult ventilation and intubation. It is useful especially in patients with massive airway bleeding or limited access to the airway and in patients in whom neck movement is contraindicated. Continued airway management with an ETC that has been placed is a reasonable option in many cases. Having thus secured the airway, it may not be necessary to abort the anesthetic or to continue with further airway management efforts. In order to avoid serious trauma to the esophagus or airway, redesigning the ETC using a softer material for the tube is advisable.
