The criteria for a complicated parapneumonic effusion include Gram stain–positive or culture-positive pleural fluid, pleural fluid pH <7.20, and pleural fluid LDH that is greater than three times the upper limit of normal of serum LDH. [2]

A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
A 2019 guideline however recommended against their general use, unless refractory shock was present. [79] Side effects associated with the use of corticosteroids include high blood sugar. [133] There is some evidence that adding corticosteroids to the standard PCP pneumonia treatment may be beneficial for people who are infected with HIV. [49]
The concept of chest drainage was first advocated by Hippocrates when he described the treatment of empyema by means of incision, cautery and insertion of metal tubes. [2] However, the technique was not widely used until the influenza epidemic of 1918 to evacuate post-pneumonic empyema, which was first documented by Dr. C. Pope, on a 22-month ...
Prior to the development of the Eloesser flap in the 1930s, the main surgical treatments for chronic tuberculous empyema were an open thoracotomy or chest tube drainage. In his original published description of the procedure, Dr. Eloesser wrote that he felt that those options were "unsatisfactory" as he felt they led to secondary infection and ...
A history of exposure to potential causes and evaluation of symptoms may help in revealing the cause the exacerbation, which helps in choosing the best treatment. A sputum culture can specify which strain is causing a bacterial AECB. [5] An early morning sample is preferred. [7] E-nose showed the ability to smell the cause of the exacerbation. [8]
