The Combitube is a blind insertion airway device (BIAD) often utilized in the pre-hospital, emergency setting. It is designed to facilitate the intubation of a patient in respiratory distress. It consists of a cuffed, double-lumen tube that is inserted into a the patient's airway facilitating ventilation. Inflation of the cuff allows the device to function similarly to an endotracheal tube and usually closes off the esophagus, allowing ventilation and preventing reflux of gastric contents.
The simplicity of placement is the main advantage of the Combitube over endotracheal intubation. When intubating with a traditional endotracheal tube, care must be taken to visually ensure that the tube has been placed in the trachea while the dual-lumen design of the Combitube allows for ventilation to proceed regardless of esophageal or tracheal placement. Generally, the tube enters the esophagus and ventilation is provided through tube number one. In the rare instance where the Combitube intubates the trachea, ventilation is provided through tube number two while tube one is clamped.
The Combitube's ease of use makes it ideal for use in the pre-hospital, emergency setting where advanced level providers capable of placing an endotracheal tube tube are often not immediately available. The drawbacks of Combitube use center around an inability to perform deep (subglottic) suctioning assuming esophageal placement.
While it has been suggested as an option by the American Heart Association and European Resuscitation Council, it is seldom used outside of the pre-hospital, emergency setting. Alternatives to the Combitube include the laryngeal mask airway (LMA), the endotracheal tube, and other BIAD's such as the King Airway.
The Combitube was invented by Austrian researchers M.Frass M.D., R. Frenzer, and J. Zahler M.D.
