Bronchoscopy
Bronchoscopy is an endoscopic 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. The construction of bronchoscopes ranges from rigid metal tubes with attached lighting devices to flexible optical fiber instruments with realtime video equipment. History The German laryngologist Gustav Killian is attributed with performing the first bronchoscopy in 1897. Killian used a rigid bronchoscope to remove a pork bone. The procedure was done in an awake patient using topical cocaine as a local anesthetic. From this time until the 1970s, rigid bronchoscopes were used exclusively. Chevalier Jackson refined the rigid bronchoscope in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bronchus
A bronchus ( ; : bronchi, ) is a passage or airway in the lower respiratory tract that conducts air into the lungs. The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus. These are the widest bronchi, and enter the right lung, and the left lung at each hilum. The main bronchi branch into narrower secondary bronchi or lobar bronchi, and these branch into narrower tertiary bronchi or segmental bronchi. Further divisions of the segmental bronchi are known as 4th order, 5th order, and 6th order segmental bronchi, or grouped together as subsegmental bronchi. The bronchi, when too narrow to be supported by cartilage, are known as bronchioles. No gas exchange takes place in the bronchi. Structure The trachea (windpipe) divides at the carina into two main or primary bronchi, the left bronchus and the right bronchus. The carina of the trachea is located at the level of the sternal angle and the fifth thoracic ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
