Official Title: Comparison of Different Bending Mode for Double-lumen Endotracheal Tube Intubation

Brief Summary: The purpose of this study is to comparing the effects of different double-lumen endotracheal tube's bending type in tracheal intubation.

Detailed Summary: Intubation with the double-lumen endotracheal tube (DLT) remains a great challenge for anesthesiologists. Although new upper airway devices, such as GlideScope(R) videolaryngoscope, had been developed for facilitating airway management, the larger size and the complexity of DLT than single-lumen tube (SLT) makes the difficulties for DLT intubation. Therefore, the investigators designed this study to investigate the effects of different bending type of DLT in tracheal intubation.

Current Primary Outcome: Main outcome measure is the successful rate of the first intubation compared with the two bending modes of DLT [ Time Frame: 12 month ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • the time needed to insert the DLT during the period of intubation [ Time Frame: 12 months ]
  • mean blood pressure (MAP) before intubation, and after intubation 1, 3,and 5 min [ Time Frame: 12 months ]
  • the incidence of hypoxemia during the period of intubation [ Time Frame: 12 months ]
    Hypoxemia is defined as the SPO2 is below 90%.
  • the heart rate (HR) before intubation, and after intubation 1, 3,and 5 min [ Time Frame: 12 months ]
  • the incidence of sore throat after extubation [ Time Frame: 12 months ]
  • the incidence of hoarseness after extubation [ Time Frame: 12 months ]


Original Secondary Outcome: Same as current
