Inclusion criteria

  • Patients undergoing thoracic surgery that require the placement of left-sided double-lumen tubes

Exclusion criteria

  • Abnoraml anatomy of tracheobronchail tree
  • Intraluminal lesion in the left mainstem bronchus
  • Anticipated difficult intubation

Treatment and study plan

Width 1000 HU/Level -450 HU

Device

Double-lumen tube size is selected according to the internal diameter of the left mainstem bronchus measured in the chest computed tomography with width 1000 HU and level -450 HU.

Width 400 HU/Level 25 HU

Device

Double-lumen tube size is selected according to the internal diameter of the left mainstem bronchus measured in the chest computed tomography with width 400 HU and level 25 HU.

Primary outcomes

  1. Air-leak at deflation of bronchial cuff

    Time frame: An expected average of 10 min after double lumen tube intubation

  2. Air-tight seal below resting volume of bronchial cuff

    Time frame: An expected average of 10 min after double lumen tube intubation
