Comparison of VentiBroncTM Anchor With Conventional Double-lumen Endobronchial Tube in Patients With High Risk of Malposition

Comparison of VentiBroncTM Anchor With Conventional Double-lumen Endobronchial Tube in Patients With High Risk of Malposition

The investigators intend to compare the group using triple-cuffed endobronchial tube (VentiBroncTM Anchor) with the group using the conventional double-lumen endotracheal tube (Shiley®) in patients at high risk of malposition of the double-lumen endotracheal tube. The aim of this study is to determine if the use of VentiBroncTM Anchor increases the success rate of optimal double-lumen intubation to left main bronchus.

Inclusion Criteria:

Patients requiring left double-lumen endotracheal tube intubation for thoracic surgery.

ASA physical status classification 2-4. Female patients aged 20-85 with a height of 160cm or less and a body mass index (BMI) of 25.0 kg/m2 or higher.

Patients requiring VentiBroncTM Anchor 33Fr or Shiley® 32Fr intubation due to a left mainstem bronchus diameter of 11mm or less on chest CT.

Exclusion Criteria:

Intraluminal lesions in the left or right mainstem bronchi. History of airway surgery. Emergency surgery.
