Bronchoscope EV-500 to video endoscopic system HD-500
Bronchoscopy (synonym BS, FBS (where F-fibro, VBS (where B-video), tracheobronchoscopy) – endoscopic method of examination of the trachea and bronchi (lower respiratory tract), as well as the upper respiratory tract (nasal cavity, nasopharynx, larynx, oropharynx) , larynx).
The bronchoscope pretends to be a thin flexible tube, with a complex internal structure, with a camera at the end.
The bronchoscope is inserted through the nasal passages into the larynx, then into the trachea and bronchi, in order to examine them.
How is the study conducted?
bronchoscopy is performed under local anesthesia (10% lidocaine spray and 2% lidocaine during the study) or under intravenous anesthesia. The patient is in a sitting or semi-sitting position. The procedure lasts a few minutes, its duration depends on the pathology that occurs during the study.
Bronchoscopy is a painless examination that does not cause difficulties in the vast majority of patients.
When is it necessary to come for a bronchoscopy?
Bronchoscopy is performed on the prescription of a doctor, usually a pulmonologist, thoracic surgeon or therapist, but doctors of other specialties can refer for bronchoscopy.
The most common indications for bronchoscopy are:
pathological changes in the lungs or mediastinum, chronic nonspecific pneumonia, the presence of a decay cavity / lung cyst, interstitial and disseminated changes in the lungs, peripheral, central and central neoplasms detected on radiography, computed tomography (CT) or magnetic resonance imaging (MRI) mediastinal lymphadenopathy of unclear etiology, suspected pulmonary tuberculosis)
signs of tracheal and bronchial stenosis, pulmonary atelectasis
prolonged cough of unknown etiology
suspicion of the presence of a foreign body in the trachea and bronchi
pre / postoperative examination in thoracic surgery
exudative pleurisy of unclear etiology
suspected airway damage
How to prepare for bronchoscopy?
To prepare for the study, it is necessary not to eat or drink 4 hours before it begins. In addition, you should:
1) Take all the medications that you are constantly taking, according to the usual schedule. This applies to the treatment of blood pressure, and inhalations for the treatment of bronchial asthma, and insulin for the treatment of diabetes, etc. ⠀
When taking the tablets in the morning, they should be washed down with a small amount of water (1-2 sips), at least 1.5-2 hours before the study. ⠀
If necessary, the introduction of short-acting insulin: or record at the earliest time, or later, to pass 3-4 hours after a meal. ⠀
Inhalations are used in any case and will not adversely affect the study.
2) Bring the necessary documents. This list includes: ⠀
Direction from the doctor (if any), where the diagnosis and purpose of the study should be indicated.
Rg- or MSCT-images or the conclusion of the radiologist. After all, without an accurate understanding of the localization of the pathology, it is impossible to purposefully collect material (eg, bronchial lavage fluid) for analysis.
Conclusions of previous studies to compare the dynamics of the disease.
Discharges from inpatient treatment in hospitals, especially during lung surgery or in the presence of cancer.
3) In the presence of severe comorbidities to be examined, and if necessary, additional examination (ECG, FZD, etc.) by a specialist (in severe asthma – a pulmonary; in severe heart failure – a cardiologist, etc.) , to identify possible contraindications to the study.
