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 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.

Eligibility criteria: Inclusion Criteria:

1. American Society of Anesthesiologists physical status I-III
2. more than 18 years of age
3. Receiving thoracic surgery with double-lumen endobronchial tube

Exclusion Criteria:

1. risk of regurgitation and pulmonary aspiration
2. history of gastroesophageal reflux
3. pregnancy
4. scheduled tracheostomy and postoperative prolonged ventilation in ICU
5. limited neck extension (\< 35°)
6. a thyromental distance less than 7 cm
7. a sternomental distance less than 12.5 cm with the head fully extended
8. mouth can not open

Primary outcomes:
measure: Main outcome measure is the successful rate of the first intubation compared with the two bending modes of DLT
timeFrame: 12 month
Secondary outcomes:
measure: the time needed to insert the DLT during the period of intubation
timeFrame: 12 months
measure: mean blood pressure (MAP) before intubation, and after intubation 1, 3,and 5 min
timeFrame: 12 months
measure: the incidence of hypoxemia during the period of intubation
timeFrame: 12 months
measure: the heart rate (HR) before intubation, and after intubation 1, 3,and 5 min
timeFrame: 12 months
measure: the incidence of sore throat after extubation
timeFrame: 12 months
measure: the incidence of hoarseness after extubation
timeFrame: 12 months
