Lung abscess – status and sputum

Lung abscess usually occurs as a complication of pneumonia, when a main disease associated infection. Lung abscess may occur without prior pneumonia - an infection in the drift any another way (gemato-, ʙronxo-, lymphogenous or traumatic). In most cases an abscess caused by Streptococcus, diplokokkom, stafilokokkom.

The character of sputum lung abscess depends on the localization process, its prevalence and development period. In the early period of development of the isolated abscess or pus, communicating with the bronchus, phlegm is released in the form of a more or less thick, sometimes slurry, usually odorless.

A break in the bronchi extensive lung abscess suddenly released a significant (200-600 Ml) the amount of sputum, often with a putrid odor. In the liquid sputum on standing formed three layers:

• Upper - mucopurulent;
• Medium - Liquid (serous);
• The bottom - purulent, who is subject to the study and contains cork Dietrich, small pieces of lung tissue in black or brown tint (from coal and hemosiderin pigment).

In some cases, after the break and release the contents of the abscess through the bronchi full cavity connective tissue overgrowth does not occur, and it continues to stand out from the sputum of different nature. It may be mucopurulent, moderately viscous or viscous, often mixed with blood, or liquid, purulent or serous-purulent with the above impurities. Putrid smell of phlegm due mainly to the presence of anaerobic microorganisms.

Microscopic examination of white blood cells found in sputum, and forming part of a decaying detritus, erythrocytes in varying amounts, fibrin, cork Dietrich, elastic fibers, indicating destruction of lung tissue. This is also evidenced by plotnovata blackish-brown necrotic fines, is a fibrous tissue with collagen and elastic fibers, inclusions of carbon pigment, hemosiderin, and crystals gematoidina.
