Abscess common sense _ general knowledge of lung
Lung, just as other organs of body, will receive infection of bacterium but inflammation, suppurate. In fact, the lung is the important organ of the respiratory system, have already received suitable protection on the organization of human body, but sometimes it is unavoidable to be infected.
Lung abscess namely lung suppurates, forms the cavity, pustule. At the very beginning perhaps but the lung presented bacterial infection, inflammation, later began necrosis in the middle of the focus, as the organization of necrosis breaks routedly and entering the bronchus, will form the cavity. The patient will present symptoms such as high fever, cough, coughing a large number of suppuration or stink phlegm,etc.. Acute the intersection of lung and most abscess can heal by drug therapy, treat in time, completely, can transfer to chronic lung abscess, need surgery to treat.
Cause of disease
There are the following three to cause factors of lung abscess:
1,The oral cavity or upper respiratory tract sucks germs: Purulent fungus suck, get through oral cavity, the intersection of nasopharynx and lower respiratory tract whether the intersection of lung and abscess have illness coming on reason that meet at most. General situation, the respiratory tract has sensitive cough reflex, can prevent sucking by mistake, after but people is at sleep soundly, not drunking, anaesthesia or mind in a trance, situation go into a coma at, mechanism will weaken or disappear cough reflex, the germ seized the opportunity and entered finally. In addition, one's own resistance drops, will cause lung abscess.
2,Blood source lung abscess: Other position such as skin, urinary tract, when infected with, germ invade the blood flow take place the intersection of suppuration and malicious the intersection of blood and disease, cause the lung infection, suppurate when the germ flows through lung with the blood.
3,Continue the hair at other lung diseases: When the lung presents other diseases such as bronchiectasis, bronchus cyst, cavity pulmonary tuberculosis, these focuses are easier to present suppurating than the normal lung tissue. It exchanges lung abscess of kindling too at the time of disease that lung cancer, bronchus stop up,etc..
Symptom
Lung abscess has illness coming on sharply, most patients have diseases such as teeth, the mouth infection, upper airway infection, pneumonia, bronchitis of swallowing department,etc., or experiences such as the operation, tired, suffering from cold,etc.. The patient has illness coming on and presents chilly, high fever, coughing, chest aching, stimulating dry cough,etc. at the very beginning. The chest aches and breathes sports relevantly, pain becomes more serious while deeplying breathe, so the patients all breathe narrow and shallowly, fast, in order to lighten pain. Patient's spirit is dispirited, weak and having no appetite, transfer with infecting aggravating from dry cough to suppuration phlegm, phlegm quantity increases gradually too, the viscous, suppuration, phlegm with the stink appear, take the blood in the phlegm sometimes. After the suppuration liquid in the focus is expectorated, symptom begins to take a favorable turn.
Physical examination
The doctor can find some characteristics while having a physical examination for the patient, such as the lung percussion presents the voiced sound, auscultation has various rales and in charge ofing respirations, can hear pleura adhesion blood vessel noise in a few cases. The longer one of course of disease often has pokes that is pointed.
Diagnosis
According to sudden to fear cold, high fever, cough a large amount of the intersection of suppuration and phlegm, cough blood symptom, diagnose the condition tentatively, but must carry on X-ray examination. The chest X-ray photograph can be seen in the lung cavity venereal disease cooking stove, wall thick and often having angry level surfaces, have soak and pieces of the intersection of form and shade Suo around, companion it is thick for pleura to increase. In addition, the bronchus radiography is helped to checking the range of amalgamating bronchiectasis and pathological change and excising greatly. Take food chocking the patient who cough should even make lipiodol or oesophageal radiography of barium meal, check, whether have oesophageal trachea Lous clearly; If need to make bronchus mirror and fetch the biopsy while needing to distinguish with lung cancer. Confirm the pathogenic bacterium, succeeding on the therapeutic foundation. Might come from just because of bacterium that phlegm bring appeared to spit oral cavity is and not a bacterium in abscess, fetch to it secretes liquid to be can be comparatively reliable close abscess with the intersection of bronchus and mirror.
Treat
The therapeutic principle of lung abscess is to resist infection actively and strengthen the phlegm liquid to guide. The antibiotic that used should cultivate the result according to the bacterium. Generally speaking, penicillin is used for treating to have illness coming on early, acute lung abscess for less than one month, the result is better, most patients can fully recover. Other daily effective antibiotic include Clindamycin alone or together with cephalosporin, or Ampicillin/Sulbactam. The patient whose immune ability drops is often infringed by the special bacterium or fungi, so need to cultivate and confirming the correct healing solution even more.
Effective antibiotic treatment 3~4 symptom begin, take a favorable turn when being about day usually, treat about symptom can disappear totally 8~12 week continuously. Only symptom totally disappears, X light reveals inflammation and suppuration are totally dissipated, only leave the fibrous shadow of small quantity and can be regarded as and fully recover.
After treating actively, the suppuration can't close and should consider the surgery treatment. The patient suitable for the operation has the following situations:
1,The disease one has not obviously taken a favorable turn after antibiotic treatment in above three months, patient breaking out continuously and repeatedly.
2,The abscess patient of chronic lung presented big hemoptysis suddenly, or when big hemoptysis was not stopped yet by positive drug therapy, should perform the operation and rescue in time.
3,Chronic lung abscess such as the one difficult to infect because the bronchus is highly blocked to control, should excise the lung after planning appropriately.
4,Chronic lung abscess and other focuses coexist, or can't totally distinguish, for instance tuberculosis, lung cancer, lung mould are infected, also need the lung to excise and treat.
