have been considered the best device for patients with difficult airways.
Balloon-tipped bronchial blockers
(BB) remain the 'technique of choice' in Paediatric patients, under the age of 6 years.
The placement of the BiVent tube and bronchial blocker
is checked by auscultation and individual lung ventilation.
Alternatively, the single-lumen tube can remain in situ and lung separation achieved with an independent bronchial blocker
. Several different tube exchange catheters are available (Cook Critical Care, Sheridan Catheter Corporation and CardioMed Supplies).
compared to double-lumen tube for one-lung ventilation during thoracoscopy.
A Fogarty catheter used as a bronchial blocker
can dislodge with coughing, change of position from supine to lateral or during surgical manipulation3.
The second method involves a single-lumen endotracheal tube with an endobronchial blocker (bronchial blocker
) to occlude the mainstem bronchus on the operative side (1).
If a major bronchus is affected, then it is desirable to isolate the contralateral lung by endobronchial intubation of the unaffected bronchus with a cuffed tube, or if feasible, to use a double-lumen tube or a bronchial blocker
