About

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.
