About this study

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.

  • more than 18 years of age
  • Receiving thoracic surgery with double-lumen endobronchial tube

Exclusion criteria

  • risk of regurgitation and pulmonary aspiration
  • history of gastroesophageal reflux
  • pregnancy
  • scheduled tracheostomy and postoperative prolonged ventilation in ICU

Treatment and study plan

the DLT bending to the right

Procedure

bending the bronchial lumen of DLT 60~90 degrees in the same side with the tracheal lumen

Other names: different bending mode of DLT

the DLT bending to the left

Procedure

bending the bronchial lumen of DLT 60~90 degree opposed to the tracheal lumen

Other names: different bending mode of DLT

Primary outcomes

  1. Main outcome measure is the successful rate of the first intubation compared with the two bending modes of DLT

    Time frame: 12 month

Secondary outcomes

  1. the time needed to insert the DLT during the period of intubation

    Time frame: 12 months

  2. mean blood pressure (MAP) before intubation, and after intubation 1, 3,and 5 min

    Time frame: 12 months

  3. the incidence of hypoxemia during the period of intubation

    Time frame: 12 months

    Hypoxemia is defined as the SPO2 is below 90%.

  4. the heart rate (HR) before intubation, and after intubation 1, 3,and 5 min

    Time frame: 12 months

  5. the incidence of sore throat after extubation

    Time frame: 12 months

  6. the incidence of hoarseness after extubation

    Time frame: 12 months
