Overview
Brief Summary
One lung ventilation (OLV) is required during thoracic procedure such as lung and esophagus surgery, and carried out by double lumen tube(DLT). Direct insertion of DLT over a fibreoptic bronchoscope (FOB) is considered more difficult and traumatic than that of a single-lumen tube. Recently, One recent simulation study demonstrated that a soft silicone DLT with a flexible, wire-reinforced bronchial tip (Fuji-Phycon tube) may shorten the time to intubation via tube exchange when compared with less compliant, polyvinyochloride(PVC) DLTs such as the Shilly or Rusch DLT. HumanBroncho® (Insung Medical, Seoul, Korea) is a new silicone DLT with a soft, flexible, non-bevelled, wire-reinforced tip. The oval shape, obtuse angle, and short lateral internal diameter of the bronchial lumen and its flexibility may allow for advancement to the trachea over the FOB easier than the Shilly tube.
In the present study, The investigators aimed to test the hypothesis that the silicone DLT would be easier than PVC DLT with regard to railroading grade over an FOB. Investigators further aimed to compare the intubation time over the FOB between the silicone DLT and PVC DLT.

Outcomes
Primary Outcomes
railroading grade
Time Frame: an average of 2 minutes
grade of ease of railroading over fibreoptic bronchoscope. 1. no difficulty passing the tube 2. obstruction while passing the tube, relieved by withdrawal and 90 degree counter-clockwise rotation(2-1) or more than 90 degree rotation(2-2) 3. obstruction necessitating more than one manipulation or external laryngeal manipulation 4. direct laryngoscope was required
Secondary Outcomes
- insertion time(an average of 2 minutes)
- number of patients with complication of hoarseness, sore throat, and swallowing difficulty(an average of 30 minutes)
- number of patients with trauma around glottis, observed by FOB(an average of 2minutes)
- number of patients with tube repositioning during the surgery(an average of 3.5 hours)
