Sputum and nasal mucus appear greenish-yellow and thick, this condition is commonly associated with an inflammatory reaction in the upper respiratory tract, due to a decrease in resistance to infection by purulent bacteria, most often Pseudomonas aeruginosa, which causes, for example, acute rhinitis, sinusitis, deviated nasal septum and nasal polyps combined with acute infections, tonsillitis, and so on. This condition is due to infection with bacteria and an increase in purulent secretions from the mucosa in the airways. Clinically, you can test the blood routine, if necessary, you can take the greenish-yellow secretion to do bacteriological culture as well as drug sensitivity test, to clarify the etiology and condition, but also to clarify the treatment program, clinically, you can choose ceftazidime, ciprofloxacin and other drugs for treatment.
