What is an electronic bronchoscope
Electronic bronchoscope is an instrument that uses modern high technology to make up a bendable endoscope of tens of thousands of very fine glass fibers only a few millimeters in diameter, inserted through the patient’s nostrils, to observe lesions inside the trachea, bronchi and lungs through a video system, and thus perform various diagnostic and therapeutic operations on diseases of the whistling system. It can directly brush and biopsy tracheal and bronchial lesions to obtain cytological, bacteriological and pathological histological diagnosis, which obviously improves the diagnosis and differential diagnosis of whistle system diseases, and provides clear, distinct and vivid high-resolution bronchial images, so that patients and families have a clear and intuitive understanding of the condition and treatment effect.
With the continuous development and improvement of related technologies, fibrinoscopy is playing an increasingly important role in the modern field of whistle medicine and cardiothoracic surgery. With advances in anesthesia, the patient’s painful experience is gradually reduced, allowing the patient to complete the examination with minimal pain.
Indications (what symptoms are present that require fibrinoscopy?)
1.Unexplained various types of lung shadows and pulmonary atelectasis.
(1) Diagnosis of lung cancer (site, cellular and pathological examination), preoperative staging and assessment, extent of resection.
(2) lavage and lung biopsy of local or diffuse lung lesions to assist in the diagnosis of etiology.
(2) Sputum examination reveals suspicious cancer cells and requires identification of lesion location (localization).
3.Inexplicable dry cough or change in nature of cough.
4.Unexplained limited asthma, vocal cord or diaphragm palsy, superior vena cava obstruction, celiac disease or pleural effusion.
5, Unexplained hemoptysis or blood in sputum, requiring clarification of the site and cause of bleeding.
6.Instead of thoracoscopy, to assist in the diagnosis of unexplained pleural diseases and the treatment of certain thoracic diseases.
7.Pulmonary infectious diseases, take specimens for pathogenic bacteria examination.
(1) Protective brush technique (PSB).
(2) Protective bronchoalveolar lavage technique (PBAL).
(3) Transbronchial transmural lung biopsy technique (TBLB).
8. Airway exploration.
(1) observation of mucosal lesions in the airway after tracheal intubation or tracheotomy or the appropriateness of the position of the intubation, etc.
(2) Observe for tracheal tears or other injuries after thoracic trauma; determine the presence of tracheoesophageal fistula.
(3) observation of the site and extent of bronchial mucosal damage after inhalation of harmful gases or gastric contents.
(4) Foreign body exploration.
Electronic bronchoscopic applications in disease treatment
The use of fiberoptic bronchoscopy and related therapeutic equipment allows for the treatment of the following conditions.
1.Removal of foreign bodies in the trachea and bronchi.
2.Extraction of endotracheal and bronchial secretions and blood clots
3.Treatment of pulmonary atelectasis, hemostasis, suction and flushing, drainage of pus, local drug injection for lung abscess, etc.
4.Extract endotracheal and bronchial secretions and perform pathogenic microorganism culture.
5.Cooperate with laser, microwave, argon knife, high-frequency electric knife and other devices to remove tumor or granulation tissue in the bronchus.
6.Patients with tracheal and bronchial stenosis can perform dilatation or place endotracheal stent.
7.Injectable drugs for lung tumors; tracheoalveolar lavage for diffuse lung diseases.
8.Guided tracheal intubation for resuscitation of critically ill patients.
Precautions for electronic bronchoscopy
I. Before examination.
1.Before performing electronic bronchoscopy, you need to perform hepatitis B five items, coagulation four items laboratory test and electrocardiogram. To save your time, please prepare the relevant tests in advance.
2. Fasting in the morning of the examination.
3.Don’t be nervous. If you have dentures, you should take them off and keep them properly, and cooperate closely with the physician so that the examination can be completed smoothly.
4.Please bring toilet paper before the examination.
II. After the examination.
1.Two hours after the end of the examination, wait for the anesthesia effect to reduce before starting to eat.
2.Where biopsy is performed, there may be a small amount of bleeding; if you cough up a lot of blood on the same day, you should come to our hospital for follow-up.
3. For outpatients who need biopsy, go to the bronchoscopy room to get the report of fibrinoscopy after retrieving the pathology examination report.
