Clinical Trial Summary

Lung isolation technique is useful for lung or heart surgeries for better visualization. Double lumen endobronchial tube and bronchial blocker are available for lung isolation. Adding disconnection technique before lung isolation is helpful to accelerate the lung deflation. However, the utility of disconnection technique has never been evaluated in comparison of double lumen tube and bronchial blocker. Therefore, the utility of disconnection technique in two different lung isolation technique, double lumen tube and bronchial blocker will be evaluated

Intervention

Other:
• disconnection technique
Before lung isolation, the ventilator stays switched-off until the carbon dioxide on the capnogram reached to zero. Then, inflate the balloon either on the double lumen tube or on the bronchial blocker.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Lung deflation score	verbal analog scale(0=no deflation, 10=complete deflation)	10 min after inflation of balloon
Secondary	time for initial placement		from beginning of intubation until confirmation of adequate placement with bronchoscope, approximately 5 minute
Secondary	time for lung deflation		from turning the ventilator off until the carbon dioxide reach to zero on capnography, within 2 min
