  Purpose

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


Condition Intervention
Anesthesia Intubation Complications
 Procedure: the DLT bending to the right
Procedure: the DLT bending to the left

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Comparison of Different Bending Mode for Double-lumen Endotracheal Tube Intubation

Further study details as provided by Kaohsiung Medical University Chung-Ho Memorial Hospital:

Primary Outcome Measures:
  • Main outcome measure is the successful rate of the first intubation compared with the two bending modes of DLT [ Time Frame: 12 month ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • the time needed to insert the DLT during the period of intubation [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • mean blood pressure (MAP) before intubation, and after intubation 1, 3,and 5 min [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • the incidence of hypoxemia during the period of intubation [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    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 ] [ Designated as safety issue: Yes ]
  • the incidence of sore throat after extubation [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • the incidence of hoarseness after extubation [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 60
Study Start Date: August 2011
Estimated Study Completion Date: August 2012
Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: the DLT bending to the right Procedure: the DLT bending to the right
bending the bronchial lumen of DLT 60~90 degrees in the same side with the tracheal lumen
Other Name: different bending mode of DLT
Active Comparator: the DLT bending to the left Procedure: the DLT bending to the left
bending the bronchial lumen of DLT 60~90 degree opposed to the tracheal lumen
Other Name: different bending mode of DLT

Detailed Description:

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.
