Brief summary
The purpose of this study is to investigate the effect of double-lumen tube thermal-softening before intubation on the success rate of tube exchange by airway exchange catheter.
Interventions
PROCEDUREnon-thermosoftening
By using airway exchange catheter, tube exchange is performed from single to double lumen tube that was put into normal saline at room temperature.
PROCEDUREthermosoftening
By using airway exchange catheter, tube exchange is performed from single to double lumen tube that was put into warm normal saline (40°C).
