简要总结
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

结局指标
主要结局
Lung deflation score
时间窗: 10 min after inflation of balloon
verbal analog scale(0=no deflation, 10=complete deflation)
次要结局
- time for initial placement(from beginning of intubation until confirmation of adequate placement with bronchoscope, approximately 5 minute)
- time for lung deflation(from turning the ventilator off until the carbon dioxide reach to zero on capnography, within 2 min)
