Fiberoptic bronchoscope refers to fiberoptic bronchoscope, which is used to suction sputum with certain effect. Fiberoptic bronchoscope is mainly used in the clinic for the diagnosis of lung lobe lung cancer, unexplained lung atelectasis, pleural effusion, recurrent pneumonia, etc. It is also used for the treatment of bronchial foreign bodies, airway stenosis and other diseases. Fiberoptic bronchoscopy can help detect early lesions and perform procedures such as polyp removal. For patients with chronic respiratory failure or uncontrolled infections, a large amount of secretions can block the airway and aggravate the condition because the patient’s cough is weak and sputum suctioning through a catheter from the nose or mouth does not completely remove the secretions. In this case fiberoptic bronchoscopy can be used to suction the airway secretions cleanly. However, it is generally not the preferred suctioning option. Tracheoscopic suctioning is an invasive operation, the clinical must grasp the indications and contraindications, it is recommended to consult the attending physician, according to the patient’s condition to decide whether to use fiberoptic bronchoscopy suctioning.
