Monochrome Video Bronchoscopes Can See Where a Surgeon's Naked Eye Can Not

Endoscopy is a very effective and quite accurate method of diagnosis. It is widely used now. Bronchoscopy or tracheobronchoscopy is an endoscopic method of examination of mucous tunic and lumen of trachea and bronchus i.e. so called tracheobronchial tree. Diagnostic examination is performed by flexible monochrome video bronchoscopes. Before bronchoscopy you should do X-ray examination of your chest. Modern bronchoscopes allow making biopsy that is the method of diagnosis as well.

Endoscopy is performed quickly in order to prevent an accidental regurgitation of food or water into airway that may happen with retching movements or cough. The last food each should occur not later than at 9 p.m. the day before the investigation. During the day of bronchoscopy you should not eat and drink before the procedure. If you take medicine, please, consult the doctor how to take it during the day of the examination.

The day before the examination you should visit the doctor. He may prescribe you a sedative before going to bed. It can reduce the possible alarm caused by the coming procedure. If you have any allergic reactions, please do not forget to tell about it before the examination. If you use dentures; the doctor will ask you to take it off because it may fall into airway or remove during the bronchoscopy. You should not wear clothing with a tight collar.

 

A local anesthesia of nasal cavity and face is made with the help of the special sprayer. The local anesthesia is necessary to relieve a pain that happens when a bronchoscope passes the nasal cavity and to neutralize a cough reflex. After the local anesthesia you may feel numbness and stuffiness in nose, tongue and palate numbness. Saliva swallowing is difficult.

The patient sits or lies during the examination.

The doctor introduces the bronchoscope and observes your tracheobronchial tree. Usually the monochrome video bronchoscopes are introduced through the nasal cavity but sometimes through the airways and mouth.

Sometimes the patient may need a microscopic investigation of the changed part of mucous tunic for more accurate diagnosis. It is called biopsy. It prolongs the investigation for one or two minutes. The procedure is painless. The majority of monochrome video bronchoscopes are equipped with the biopsy port. Usually it is plastic and can be loosen by twisting. But the doctor can change it by applying adhesive to the biopsy port and replaces it by the stainless steel biopsy port.

The diameter of all monochrome video bronchoscopes is essentially smaller than the lumen of your trachea and bronchus. So, you should not be afraid that you might suffocate during the procedure. Your breathing will not be affected during the examination.

How to behave after the bronchoscopy? To prevent the food or liquid in your trachea you can eat or drink when the feeling of tongue and pharynx numbness stops. Usually it takes about 20 or 30 minutes. After a biopsy has been made the doctor defines the time of food intake.

Usually monochrome video bronchoscopes are equipped with the tube of 6.2 mm. It is easy in usage and has the wide spectrum of application. The instrumental canal of 2.8 mm in diameter allows using the additional endoscopic instruments. It makes the device perfect for different therapeutic procedures,

The monochrome video bronchoscopes are equipped with endoscopic video processor. The minimum set includes a video bronchoscope, a video processor and a monitor. An assistant will usually maintain the database, data archive, endoscopic pictures archive.
