Lung abscess lung abscess_ general knowledge
Lung abscess (lung abscess) It is the suppurative infection of lung caused by many kinds of pathogens, it is the infective inflammation that the lung organizes to be early, then necrosis, liquefaction, periphery have granulation that organizes surrounding and forming abscess. The clinical feature is the hyperpyrexia, coughs, abscess breaks and enters the bronchus routedly, expectorates the discredited phlegm of a large amount of suppuration. The X-ray reveals that includes the flat cavity of angry liquid. Happen in the meridian of life more, the man exceeds women. Since antibiotic is employed extensively, the morbidity is obviously reduced.
[Mechanism ] with having illness coming on of the cause of disease
Acute the intersection of lung and bacterium that abscess infect generally and oral cavity, upper respiratory tract check bacterium to be compatible often, including the aerobic, and concurrently sex detests oxygen and detests oxygen bacterium. In more than ten years in the past, because the anaerobe trains the progress of technology, the anaerobe of acute sucking pneumonia and lung abscess infects Damien 85% - 94% . Report is sheerly that lung abscess that the anaerobe is infected with accounts for 58%; Aerobic to mix with anaerobe and infect and account for 42%. More important anaerobe is peptone streptococcus, peptone coccus, nuclear grains of shuttleless loom -shaped bacillus, produce the intersection of melanin and bacillus, the intersection of oral cavity and the intersection of inflammation and bacillus and the intersection of honour and coccus,etc. Wei; A common one aerobic and sex anaerobe the intersection of pneumonia and coccus, golden yellow staphylococcus, dissolving courageous and upright streptococcus, white bacillus of CrayResearch, Escherichia coli, green suppuration bacillus, bacillus out of shape,etc..
According to infecting the route, lung abscess can be divided into the following types.
First, sucking lung abscess
The pathogen sucks main reason to have illness coming on for lung abscess through the mouth, nasopharynx. Under the normal situation, the respiratory tract has sensitive cough reflex, can prevent sucking by mistake. But as there are suppuration secretion such as tonsillitis, nasal sinusitis, dig trough suppuration overflowing or decayed tooth; Oral cavity, nose, clot behind the operation of swallowing etc., the intersection of tooth and dirt or vomit,etc., in lose consciousness, anaesthetize under the situation, or is influenced by inducement such as being cold, extremely tired, whole body is immune to defend the function to reduce with the respiratory tract, can inlet lung into various pollutant, cause detailed bronchus block by trachea when sound sleep, pathogens are bred but have illness coming on. Sucking lung abscess is often a single shot, it is relevant that it has illness coming on in the position and dissects structure and position. The pars dextra bronchus is relatively steep and straight, and the pipe diameter is relatively thick, it is apt to suck the right lung to suck things. While lying supine in the location,it is good for hair at leaf back segments upper or under there last section is leaf; The seat mistiming is sucked, the good hair is after the lower leaf the basis section; Right side, when the location, easy to send the intersection of leaf and first period of or the intersection of armpit and inferior Section that back segment form at right.
, then sending lung abscess of second
Continuing sending lung abscess until some bacterial pneumonia, bronchiectasis, the intersection of bronchus and cyst, the intersection of bronchus and lung cancer, the intersection of pulmonary tuberculosis and cavity,etc. continue and take place and is infected with; The intersection of lung and neighbouring the intersection of organ and suppurative pathological change, diaphragm lay abscess for instance, and abscess, backbone abscess, or esophagus punch infect, wear out to lung abscess that the lung form around the kidney; Should notice * amebic liver abscess easy to take place on right the intersection of liver and top, apt to wear out from diaphragm to right the intersection of lung and lower leaf, form * amebic lung abscess.
