bronchial blocker

Abbreviation: BB
A device for facilitating single-lung ventilation during thoracic surgery or thoracoscopy.

Potential complications of the device include dislodgement, misplacement, or accumulation of fluid behind the blockade.

Experience with the Arndt paediatric bronchial blocker. Br J Anaesth 2004; 94:92-94.
One-lung ventilation can be provided in children by use of a range of methods such as selective endobronchial intubation, use of bronchial blockers (including the use of Fogarty or Foley catheters for this purpose), univent tubes and in older, larger children, a double-lumen tube (2).
Time required for position: from inserting the bronchoscope until satisfactory placement of the bronchial blocker (Coopdech, Arndt or Univent group) or the endobronchial lumen of the double-lumen tube.
Bronchial blockers including Fogarty catheters have been used in small children (22).
The section also contains practical guidance for the selection of double-lumen tubes and bronchial blockers, as well as trouble-shooting algorithms for the difficulties which can arise.
