Table 3 Comparison of the number of bronchoscopies during initial placement and on lateral position, total malposition intraoperative and reposition manoeuvre intraoperative

From: Comparison of the accuracy of three methods measured the length of the right main stem bronchus by chest computed tomography as a guide to the use of right sided double-lumen tube
