Utility of Disconnection Technique for One Lung Ventilation

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

Treatment and study plan

disconnection technique

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.

Primary outcomes

  1. Lung deflation score

    Time frame: 10 min after inflation of balloon

    verbal analog scale(0=no deflation, 10=complete deflation)

Secondary outcomes

  1. time for initial placement

    Time frame: from beginning of intubation until confirmation of adequate placement with bronchoscope, approximately 5 minute

  2. time for lung deflation

    Time frame: from turning the ventilator off until the carbon dioxide reach to zero on capnography, within 2 min
