What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
repositioning method for left-sided double lumen tubesProcedure or surgery
When a left-sided double lumen tube were placed in right mainstem bronchus, after withdrawing the tube into mid-trachea, it was re-advanced with patient's head turned right and counterclockwise rotation of the tube.
