“…[ 10 ] The Fuji-Phycon DLT (Silbroncho ® , Fuji Systems, Tokyo, Japan) was found to be easier to pass over an AEC compared with both the Rusch (Bronchopart ® , Teleflex, Research Triangle Park, NC) and Mallinckrodt (Broncho-Cath ® , Covidien, Mansfield, MA) DLT warrants consideration in patients with difficult airway [ Table 1 ]. [ 10 ] The flexibility and the 45° angulated distal bevel of the reinforced bronchial lumen of the Fuji-Phycon DLT can potentially facilitating passage of the DLT into the glottis. In contrast, the Rusch and Mallinckrodt DLTs have a bronchial end that is cut perpendicular to the axis of the tube (i.e., a square cut) or with a very short bevel, respectively.…”
