Arm && Interventions

Group	Intervention	Description
video laryngoscope and chest CT iminge	video laryngoscope and chest CT iminge	First,the operator calculate the distance between the carina and the glottis by CT image and make a marker on the Uniblocker. Then the operator inserted the Uniblocker into the trachea and advanced toward the left main-stem bronchus via the video laryngoscope untill see marker just at the glottis then stopped the insertion .Second, a single lumen tube with appropriate size was intubated via video laryngoscope into the appropriate depth.Third,the Fiberoptic bronchoscopy(FOB) was inserted into single lumen tube to assess the position of the Uniblocker and the injuries of bronchi and carina
Conventional intubation of Uniblocker	Conventional intubation of uniblocker	First, a conventional single lumen tube (SLT) was inserted into trachea at optimal depth via video laryngoscope. Second, a Uniblocker was inserted through SLT and directed to the left main-stem bronchus. Third, an FOB was inserted into the SLT to adjust the Uniblocker to optimal position and assessed the injuries of bronchi and carina.
