The use of bronchial blockers
for providing one-lung ventilation.
The Univent[TM] tube (Fuji Systems Corporation, Tokyo) is a single-lumen tube with an incorporated channel for the bronchial blocker
. Its shape is similar to that of a standard endotracheal tube.
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.
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.
