Basic Information

• Recruitment Status: COMPLETED

Brief 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

Conditions

Pneumothorax

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: OTHER
• Blinding Strategy: SINGLE

Study Groups

DLT(Double Lumen Tube) group

disconnection technique will be applied

Group Type: EXPERIMENTAL

disconnection technique

Intervention Type: OTHER

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.

BB(Bronchial Blocker) group

disconnection technique will be applied

Group Type: EXPERIMENTAL

disconnection technique

Intervention Type: OTHER

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.
