Therapeutic Procedural Complication
Conditions
Brief summary
To measure the distance between the upper edge of the thyroid cartilage to the upper edge of the sternum add the distance from the upper edge of the sternum to the carina was calculated according to the chest CT scans as a guide to the placement of Uniblocker without the aid of FOB.
Detailed description
In previous study, the investigators found Chest computed tomography (CT) image can accurately predicting the optimal insertion depth of Uniblocker,however in some hospital the CT scan performed for the preoperative surgical evaluation without the vocal cords slices. If a more extensive CT scan was needed for obtaining a more reliable image of the vocal cords,the additional exposure dose would be a major disadvantage of the method.So the investigators measure the distance between the upper edge of the thyroid cartilage to the upper edge of the sternum add the distance from the upper edge of the sternum to the carina calculated according to the chest CT scans as a guide to the placement of Uniblocker without the aid of FOB.
Interventions
OTHERThe measured distance
