's general knowledge of cause of disease of lung abscess
Acute the intersection of lung and the intersection of infection and bacterium of abscess, often deposit the fungus for general upper respiratory tract, a buccal one. Often for mix, infect, aerobic anaerobic the intersection of leather and getting blue positive negative coccus and bacillus. Among them the most common pathogen is staphylococcus, streptococcus, pneumonia coccus, shuttleless loom -shaped fungus and spirillum,etc.. The anaerobe, to the importance of the suppurative infection of lung, because of training the improvement of technology, paid attention to in recent years. 1974 reports such as Gorbach and Bartlett,etc., the anaerobe of sucking pneumonia and lung abscess was infected and accounted for 85%- 90%; Bartlett,etc. reports 45 cases of acute lung abscess isolate the materials of 114 of anaerobe, the infeted of anaerobe account for 58%, aerobic fungus mix the infeted and account for 42% with anaerobe. More important anaerobe has peptone streptococcus, peptone coccus, nuclear grains of shuttleless loom -shaped bacillus, one kind of bacillus belonging to, tiles that hold coccus, spirillum etc.. Besides above-mentioned anaerobe, have aerobic or and concurrently sex anaerobe store in. The foreign report has a liking for due to bacillus pneumonia of lung legion in recent years, nearly 25% form the abscess.
The morbidity principle of lung abscess is closely linked to cause of disease, can divide the following aspects.
(1) Sucking lung abscess and pathogen are sucked through the mouth, nasopharynx, the main reason to have illness coming on as lung abscess. Tonsillitis, nasal sinusitis, tooth's socket suppuration overflow or suppuration secretion such as the tooth age; Clot after oral cavity, nose, swallowing department operation; Tooth dirt or vomit,etc., is losing consciousness, under situations such as general anesthesia,etc., are being sucked in the lung by the trachea, cause the thin bronchus to block, pathogens can be bred and caused a disease. In addition, some patients fail to find the obvious inducement, the case of the domestic and foreign report is 29.3% and 23% respectively. Because may be influenced by inducement such as being cold, extremely tired, immune state and respiratory tract of whole body defend the function to lower, suck buccal the intersection of pollution and secretion and have illness coming on when sound sleep. It is originally type often single hairdo. It is relevant that it takes place and dissects structure and body posture. Because the total bronchus of right is in vain straighter, and the pipe diameter is relatively thick, the sucking secretion is apt to suck the right lung, so the right lung has illness coming on and exceeds the left lung. It is neither while lying supine nor good for hair at leaf back segments upper or under there last section is leaf; At seat, easy to take place on the intersection of basis and section under lower leaf. Right side, when the location, easy to send the intersection of leaf and first period of and the intersection of armpit and inferior Section that back segment form at right.
(2) Blood source septicaemia and suppuration and poisonous blood disease of due to lung abscess skin wound, infecting with, furuncle carbuncle, osteomyelitis, postpartum pelvis infecting, membrane inflammation in the bacterial heart of subnormal temperature,etc, pathogen ( Most are Jin Portugal's fungus) , the poisonous embolus of suppuration, is brought to the lung by the tiny loop, cause small vascular thromboembolism, lung to organize inflammation and necrosis, form abscess. Pathological change is often for the occuring frequently, it is sure to be distributed not to have, often happen in the edge portion of two lungs.
(3) Continue taking place lung abscess and continue more hair at other diseases, for instance golden yellow staphylococcus and pneumonia bacillus pneumonia, cavity pulmonary tuberculosis, bronchiectasis, bronchus cyst and bronchus cancer,etc. are continued and taken place and is infected with, can cause lung abscess. Lung neighbouring organ suppurative pathological change or traumatism infect and diaphragm lay abscess and abscess, juxtaspinal abscess, esophagus punch etc. around the kidney, pierce through and form abscess to the lung.
(4) * amebic lung abscess continue more hair at * amebic liver abscess. Kind to take place on the top of the right leaf of liver because of liver abscess, it is apt to pierce through the skin of diaphragm to the lower leaf of right lung, form * amebic lung abscess.
