Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control group

Intubating a manufacturer-provided-angled double-lumen tube (=Conventional-angled group,"MallinckrodtTM endotracheal tube", Covidien)

Group Type ACTIVE_COMPARATOR

Mallinckrodt endobronchial tube with a conventional angle

Intervention Type DEVICE

Inserting a manufacturer-provided conventional-angled tube

Tube angle modification

The angle of the double lumen tube(MallinckrodeTM endotracheal tube) is modified individually.At sniffing position, the distal tip of the tube is placed at the patient's cricoid cartilage level and the tube is bent at the intersection point of the two airway axes (oropharyngeal axis and tracheal axis) with an angle between the two axes.

Group Type EXPERIMENTAL

Mallinckrodt endotracheal tube with a modified angle

Intervention Type DEVICE

At sniffing position, the distal tip of a double-lumen tube is located at the patient's cricoid cartilage level and then the tube is bent at the intersection point of oral axis and the pharyngolaryngeal axis with an angle between the two axes.
