Benign or malignant lung tumors
Conditions
Interventions
Head Rotation Group:During insertion of the bronchial blocker through the laryngeal mask airway, an assistant gently rotated the patient's head leftward by approximately 60°, while the operator advanc
Neutral Position Group:The head is in the neutral position. The operator, under the direct vision of the bronchoscope, adjusts the direction of the occluder on the hilum and then pushes it forward.
