132 participants in 3 patient groups

39 Fr double lumen group

Experimental group

Description:

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
