The large amount of cough green sputum indicates that there is bacterial infection in the lower respiratory tract, such as bronchitis or pneumonia caused by Pseudomonas aeruginosa infection of the lower respiratory tract. For such patients, blood routine test and sputum culture should be improved to understand the pathogenic source of infection and drug sensitivity test, and lung X-ray or CT should be performed to determine the degree of infection. When green thick sputum appears, patients need to use corresponding anti infective drugs according to their condition. For example, mild cases can take levofloxacin, moxifloxacin, cefdinir, cefixime, etc. Those with thick sputum that is difficult to cough up can also take oral expectorant drugs, such as Fodosteine Tablets, Ambroxol Tablets, etc. For those with a large amount of cough green sputum, especially when bronchiectasis is complicated with infection, oral anti-inflammatory drugs may not be good, and patients need intravenous drip of corresponding antibiotics for anti-inflammatory treatment.
