NCT02190032

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.

Conditions

Outcome Measures

Primary Outcomes (1)

  • The time taken to intubate a double-lumen tube

    The time taken to insert the tube begins when the laryngoscope passes the patient's lips and ends when the tube passes the vocal cords

    within 60 sec

Secondary Outcomes (3)

  • The number of attempts needed for successful intubation

    Intubation

  • The time taken for the first attempt of intubation

    within 60 sec

  • Postoperative sore throat, hoarseness or dysphagia

    30 minutes and 24hours after extubation

Other Outcomes (2)

  • Hemodynamic change

    1, 3 and 5 min after intubation

  • Intubation difficulty scale score

    At intubation

Study Arms (2)

Control group

ACTIVE COMPARATOR

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

Device: Mallinckrodt endobronchial tube with a conventional angle

Tube angle modification

EXPERIMENTAL

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.

Device: Mallinckrodt endotracheal tube with a modified angle

Interventions

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.

Also known as: Tube angle modification, ("MallinckrodeTM endotracheal tube", Covidien)
Tube angle modification

Inserting a manufacturer-provided conventional-angled tube

Also known as: Mallinckrodt endobronchial tube, Covidien, with conventional-angled tube
Control group
