Everything about Combitube totally explained
A
combitube is a device designed to facilitate the blind
intubation of a patient. It consists of a cuffed double-lumen tube with one blind end. Inflation of the cuff allows the device to function as an
endotracheal tube and 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 ensure that the tube has been placed in the trachea, and not the oesophagus. The dual-lumen design of the Combitube allows for ventilation to proceed regardless of where the tube ends up. If the tube is placed into the oesophagus, ventilation is provided through one tube, and if it winds up in the trachea, ventilation is provided through the other tube.
The drawbacks to Combitube use centre around an inability to perform deep (subglottic) suctioning.
While it has been suggested as an option by the
American Heart Association and
European Resuscitation Council, it's seldom used. The main alternatives are the
laryngeal mask airway (LMA) and the endotracheal tube.
The tube was invented by three Austrian researchers :M.Frass M.D., R. Frenzer, J. Zahler M.D.
