The process of fiberoptic bronchoscopy for lung cancer examination

Patients with lung cancer can undergo fiberoptic bronchoscopy. The specific examination process is as follows:

Intubation

Intubation through the nose, mouth, or trachea; the patient lies on his back with a thin pillow under his shoulders, his head tilted back slightly, and he breathes calmly. The operator stands beside the patient's head. Sitting position: Sit on an examination chair with your head tilted back slightly, and the operator stands on the opposite side. Key points for insertion: The operator holds the fiberoptic bronchoscope operating part with his left hand, rotates it left and right as needed, and turns the angle adjustment knob with his thumb. At the same time, the index finger of his left hand can press the suction tube mouth for suction. The right hand holds the mirror body and slowly inserts it. When inserting through the nose, the mirror tube should be inserted along the nasal passage, adjust its direction and the refractive power of the eyepiece, see its anatomical structure clearly, and allow the mirror body to enter slowly. Do not use force. When the end of the mirror has not reached the throat, find the epiglottis, adjust the angle of the mirror, and pass the mirror end around the back of the epiglottis to see the glottis clearly. Ask the patient to take a deep breath, and quickly insert it into the trachea when the vocal cords are abducted. This step should be light and agile to avoid violent impact on the vocal cords.

observe

After the endoscope enters the trachea, turn the angle adjustment knob to make the field of view face the tracheobronchial cavity and continue to insert it. Carefully observe the tracheal carina, the bronchial openings and cavities of each lobe segment. Generally, check the healthy side first, then the affected side. Avoid the endoscope being too close to the tracheal wall to avoid bleeding. The suction time should not be too long to avoid hypoxia.

Remove the mirror

When removing the mirror, completely relax the adjustment rod to return it to its natural position for smooth removal.
