What Is a Lung Infection?

Pneumonia

Definition of lung infections

Pneumonia

2. Refers to the inflammation of the lung parenchyma, including the terminal airway, alveolar cavity, and interstitial lung. The most common cause of infection is infection, which can also be caused by physicochemical, immune, and drugs.

3. Among them, infections are collectively referred to as pulmonary infections. Among them, pneumonia is more typical and representative.

Classification of lung infections

Etiological classification

1. Bacterial pneumonia such as Streptococcus pneumoniae (Pneumococcus), Staphylococcus aureus, Streptococcus A type, Klebsiella pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, Escherichia coli, Green Pseudomonas and so on.

2. Pneumonia caused by atypical pathogens such as Legionella, Mycoplasma and Chlamydia.

3. Viral pneumonia such as coronavirus, adenovirus, influenza virus, cytomegalovirus, herpes simplex virus and so on.

4. Fungal pneumonia such as Candida albicans, Aspergillus, Actinomyces.

5. Pneumonia caused by other pathogens such as Rickettsia, Toxoplasma, protozoa, parasites such as pulmonary hydatid, lung fluke, and schistosomiasis). People with low immunity (such as those with AIDS) are likely to be infected with Pneumocystis carinii, Legionella, Mycobacterium avian, Tuberculosis, and Toxoplasma.

6. Pneumonia caused by physical and chemical factors such as radiation pneumonia, gastric acid inhalation, chemical pneumonia caused by drugs, etc.

7. Mycoplasma pneumonia is caused by mycoplasma infection.

Signs and symptoms of lung infection

Dyspnea, changes in body temperature, cough, increased sputum volume and sputum properties.

Causes of lung infections

Inhalation injury, tracheotomy or intubation, aspiration, pulmonary edema, atelectasis, shock, surgical anesthesia, invasive wound infection, suppurative thrombophlebitis, etc.

Diagnosis of lung infections

1. Pay attention to inhalation injury, tracheotomy or intubation, aspiration, pulmonary edema, atelectasis, shock, surgical anesthesia, invasive wound infection, and suppurative thrombophlebitis.

2. Pay attention to dyspnea, changes in body temperature, cough, increased sputum volume and sputum properties. Clinical symptoms should be distinguished from burn toxemia or sepsis.

3. Medical examination. Patients with severe burns often have chest burns, making it difficult to obtain accurate chest signs. Therefore, you should check carefully for breathing changes and rales.

4. To clearly infect the bacteria, airway endocrine culture should be done regularly, preferably bronchial lung lavage fluid culture to prevent pollution.

5. Chest X-ray examination. The diagnosis of most lung infections after burns depends on X-rays. Chest radiographs should be performed routinely after the injury and regularly reviewed later. The X-ray manifestations of pneumonia can be divided into three types: small focus, large focus and large leaf, and small focus pneumonia is the most common.

Lung infection treatment plan

1. Clear the original lesion. Those with inhalation injury or severe burns on the face and neck should strengthen airway management, effectively remove airway secretions and necrotic mucous membranes, and promote airway wound healing. Hematogenous pneumonia should control sepsis and clear away distant lesions.

2. According to the results of sputum culture or reference wound or blood bacteria examination, it should be given intravenously, and antibiotics can also be aerosolized at the same time or an appropriate amount of antibiotics can be added to the lavage fluid.

3. Concurrent respiratory insufficiency should be treated as respiratory insufficiency.
