Design outcomes

Primary

Measure	Time frame
To compare the first success rate of left DLT placement into left main bronchus using 110 degree anticlockwise rotation with respect to conventional 90 degree rotation.Timepoint: after DLT placement	—

Secondary

Measure	Time frame
To determine the true mean anatomic angle of left main bronchi with respect to trachea using three-dimensional CT scan (3D CT) in Indian population To compare the incidence of carinal mucosal injury between the above two degree of rotation groups. Timepoint: preoperative after successfull placement of DLT	—
