Modified Angled Tube vs. Conventional Angled Tube in Double-lumen Endotracheal Tube Intubation

Not Applicable

Completed

• Conditions: Intubation, Intratracheal; Thoracic Surgical Procedures

• Registration Number: NCT02190032
• Lead Sponsor: Samsung Medical Center

Brief Summary

The investigators are trying to compare the individually modified-angled tube and the conventional-angled tube in ease of double lumen endotracheal tube insertion and the incidence of related postoperative complications.

Detailed Description

Inserting a double lumen endotracheal tube is somewhat more difficult than a single lumen tube intubation because of its larger outer diameter and the more rigid feature. Moreover, the airway axes (oral-,pharyngeal-, and laryngotracheal axis) are not always straight under sniffing condition. Therefore, to make easy to insert a double-lumen tube and reduce the tube-related complications, we are trying to compare the individually angle-modified tube and the manufacturer-provided-angled tube.
