#Double lumen tube free#

The right and left sided DLTs are so named according to the bronchus they are supposed to enter. There are several species of these devices the major distinction one needs to be aware of is the very important difference between a right-sided and a left-sided dual lumen tube. Now, in some detail: Anatomy of the double lumen tube Airway oedema - the size of the tube and its rigidity may give rise to greater tracheobronchial injury, with more oedema and therefore an increase in the difficulty of re-intubation.Bronchial injury - the bronchial cuff may put too much pressure on the bronchial wall (which is far from robust) and cause a pressure area on top of that it is possible to rupture the bronchus with a rough intubation.Tracheal injury - the tube is rigid and thick, more likely to damage the trachea on insertion, and there is a large cuff to inflate which may put additional pressure on the tracheal walls.Success of tracheal intubation, but failure of lung isolation - the tube fails to isolate the correct lung.The chance of getting it wrong is considerably greater, even with expertise. Failure of intubation - as previously mentioned, these things are not exactly quick or easy to insert.Specially designed eccentric balloons for right-sided DLTs, preventing the obstruction of the right upper lobe bronchus.Small volume endobronchial cuff, to prevent bronchial mucosal ulceration.

Soft silicon portion of the ventilator connector, to ensure that it can be clamped safely without fracturing.Blue designation for the endobronchial components.Radio-opaque line to help gauge position on chest X-rays.Murphy's eye to protect against occlusion.High volume low pressure cuff to seal the trachea.Markings to indicate depth of insertion.
