The Airtraq® laryngoscope allowed placement of 35- and 37-French DLTs in ten patients without complications. Based on our experience, the Airtraq® laryngoscope accepts 35- and 37-French DLTs, although the latter was somewhat thick against the channel of the scope. It is probably impossible to insert a 39-French DLT (outer diameter = 13 mm).
Despite this limitation, the Airtraq® laryngoscope appears to be an alternative approach for DLT placement when the physician encounters cases in which the conventional Macintosh laryngoscopy results in unsuccessful DLT placement.
Note: The cases were performed using a Regular size Airtraq. A new Airtraq model specifically designed to accommodate DLT tubes up to 41-French will soon be available.
