Preventing Blood Leakage of Bronchial Cuff
Conditions
Keywords
bronchial cuff, double lumen tube, blood tight seal
Brief summary
The purpose of this study is to find the adequate additional bronchial cuff volume after achievement of air-tight seal, that can achieve blood-tight seal(preventing leakage of blood through cuff) in double lumen tube
Interventions
PROCEDURE39 Fr double lumen tube group
additional bronchial cuff volume is decided according to up-and-down biased coin design sequential method, by incremental volume of 0.1 ml
PROCEDURE37 Fr double lumen tube group
additional bronchial cuff volume is decided according to up-and-down biased coin design sequential method, by incremental volume of 0.1 ml
PROCEDURE35 Fr double lumen tube group
additional bronchial cuff volume is decided according to up-and-down biased coin design sequential method, by incremental volume of 0.1 ml
