When inflammation causes pleural effusion, treatment is mainly aimed at fighting infection. Pleural effusion is usually caused by inflammation and infection, cirrhosis, trauma and other factors, resulting in increased formation or decreased absorption of fluid in the pleural cavity, and the occurrence of pleural effusion will cause patients to have difficulty breathing, coughing and other uncomfortable symptoms. If the pleural effusion is caused by inflammation and infection, its treatment is mainly aimed at anti-infection, and can be treated with ceftriaxone, levofloxacin hydrochloride and other drugs under the guidance of the doctor, and the symptoms will gradually recover after the inflammation is controlled. If the amount of fluid accumulation is large, if necessary, thoracentesis can be used to draw fluid or placed in the chest closed drainage tube drainage. Patients should pay attention to appropriate exercise during treatment to improve body resistance and promote recovery. When pleural effusion occurs in daily life, patients should go to the hospital for examination in time, and after clarifying the cause of the disease, they can take the treatment for the cause.
