The appearance of cough with green sputum indicates the occurrence of Pseudomonas aeruginosa infection, also known as Pseudomonas aeruginosa infection, in the respiratory system. The infection is more serious at this time, and it is better to be hospitalized for intravenous fluid treatment, which is more effective. It is also necessary to take intravenous antibiotics for anti-inflammatory treatment. At this time, it is also necessary to drink more water, which can help dilute the phlegm and promote the discharge of phlegm, which is helpful for the recovery of cough. If you are not allergic to penicillin, you can take penicillin intravenously for anti-inflammatory treatment, such as meloxicillin and piperacillin. If you are allergic to penicillin, you can also use cephalosporin antibiotics for intravenous drip treatment, such as cefminox, cefoperazone, ceftazidime, and preferably nebulized inhalation of aminoglutethimide hydrochloride to promote the discharge of sputum.
