Use of the bronchoscope mildly irritates the lining of the airways, resulting in some swelling and inflammation, as well as hoarseness caused from abrading the vocal cords. If this abrasion is more serious, it can lead to respiratory difficulty or...
bleeding of the lining of the airways.
The bronchoscopy procedure is also associated with a small risk of disordered heart rhythm (arrhythmia), heart attacks, low blood oxygen (hypoxemia), and pneumothorax (a puncture of the lungs that allows air to escape into the space between the lung and the chest wall). These risks are greater with the use of a rigid bronchoscope than with a fiberoptic bronchoscope. If a rigid tube is used, there is also a risk of chipped teeth. The risk of transmitting infectious disease from one patient to another by the bronchoscope is also present. There is also a risk of infection from endoscopes inadequately reprocessed by the automated endoscope reprocessing (AER) system. The Centers for Disease Control (CDC) reported cases of patient-to-patient transmission of infections following bronchoscopic procedures using bronchoscopes that were inadequately reprocessed by AERs. Investigation of the incidents revealed inconsistencies between the reprocessing instructions provided by the manufacturer of the bronchoscope and the manufacturer of the AER; or that the bronchoscopes were inadequately reprocessed.

Bronchoscopy can be performed via the patient's mouth (A) or through the nose (C). During the procedure, the scope is fed down the trachea and into the bronchus leading to the lungs (B), providing the physician with a view of internal structures (D). (Illustration by GGS Inc.)

Other Information
Bronchoscopy is a technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument (bronchoscope) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy. This allows the practitioner to examine the patient's airways for abnormalities such as foreign bodies, bleeding, tumors, or inflammation. Specimens may be taken from inside the lungs: biopsies, fluid (bronchoalveolar lavage), or endobronchial brushing. The construction of bronchoscopes ranges from rigid metal tubes with attached lighting devices to flexible fibreoptic instruments with realtime video equipment.
