Thermosoftening of Double-lumen Tube for Airway Exchanger Catheter

Effect of Thermal-softening of Double-lumen Endobronchial Tubes on Success Rate of Airway Exchange Catheter

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.

Inclusion Criteria:

• Patients undergoing thoracic surgery that requires bronchoscopy study before the placement of double-lumen tubes

Exclusion Criteria:

• Preoperative hoarseness or a sore throat
• History of upper airway diseases
• Anticipated difficult airway
