From what reason was lung abscess caused? 's general knowledge
Emergence and development of lung abscess, often have three following factors: Bacterial infection; The bronchus is blocked; Resistance is lowered all over. There are two major kinds of clinical and common causes of disease: The blood source is infected and infected with the trachea. The blood source is infected, mainly caused by septicaemia and suppuration and poisonous blood disease, pathological change is extensive often in order to occur frequently, mainly adopt the medicine treatment. Trachea infect come from respiratory tract or upper the intersection of digestive tract and with bacterium secretion mainly, after sleeping, going into a coma, being drunk, anaesthetizing epilepsy breaking out, brain blood vessel accident, sucked in trachea and lung, cause the small bronchus to block, in a situation that human resistance lowers, will bring out lung abscess.
Bronchus block the intersection of lung and section of end take place lung piece and inflammation change, then cause the intersection of lung and sections of vascular thromboembolism produce lung, organize necrosis and liquefaction far, the pleura lung tissue around reacted, formed a piece of abscess with a certain limit at last. After abscess takes shape, through acute and sub-acute stage, for instance, the bronchus can not be guided unobstructedly, do not infect and control completely, change over to chronic stage progressively. The repeated outbreak that is infecting, interlock in the course of developing, is being given much trouble lung and bronchus and destroyed, repair in an organized way; Pathological change that has lungs to organize, also there is pathological change of the bronchus pleura; There is acute inflammation; There is chronic inflammation; Show as one the intersection of suppuration and in lung organize mainly, have the intersection of quality and inflammation and at various degrees fiber take among the lung around, the relevant bronchus produced obstructing and expansion at various degrees.
Chronic lung abscess has three following characteristics: Abscess position occupy more about lung section or lobe of the lung the intersection of table and shallow department at the beginning; The suppuration always communicates with one or more little bronchuses; Abscess spreads outwards and expands, is not limited by lung section, demarcation line of lobe of the lung by later period, and it can step on section, across leaf, form by room the destruction venereal disease cooking stoves of thes many that be communicated with each other.
