Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
39 Fr double lumen group
patients are assigned to 35 Fr, 37 Fr, 39 Fr double lumen tube group according to their left main bronchus diameter measured by preoperative chest CT, to minimize difference between main bronchus diameter and bronchial tip diameter of double lumen tube
39 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
37 Fr double lumen group
patients are assigned to 35 Fr, 37 Fr, 39 Fr double lumen tube group according to their left main bronchus diameter measured by preoperative chest CT, to minimize difference between main bronchus diameter and bronchial tip diameter of double lumen tube
37 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
35 Fr double lumen tube group
patients are assigned to 35 Fr, 37 Fr, 39 Fr double lumen tube group according to their left main bronchus diameter measured by preoperative chest CT, to minimize difference between main bronchus diameter and bronchial tip diameter of double lumen tube
35 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
