What causes parapneumonic effusion?
Both viruses and bacteria can cause parapneumonic effusions, but it is the latter that is the most common cause of empyema thoracis. A very common cause of infection of the chest cavity is trauma. Any hemothorax that is not adequately evacuated can result in an empyema.
How do you manage parapneumonic effusion?
Antibiotics – All patients with suspected (or diagnosed) parapneumonic effusion or empyema should be treated with antibiotics. Antibiotic therapy should be administered promptly and not delayed for sampling or drainage procedures.
Is parapneumonic effusion Transudative?
Infectious pleural effusion, called parapneumonic effusion, is the most common of exudative effusions (3).
When do you drain parapneumonic effusion?
Indications for urgent drainage of parapneumonic effusions include (1) frankly purulent fluid, (2) a pleural fluid pH of less than 7.0-7.1, (3) loculated effusions, and (4) bacteria on Gram stain or culture.
What size pleural effusion should be drained?
Removal of 400-500 mL of pleural fluid is often sufficient to alleviate shortness of breath. The recommended limit is 1000-1500 mL in a single thoracentesis procedure.
Which patients with a parapneumonic effusion need a chest tube?
Chest tubes should be placed for some cases of complicated effusion and for all cases of empyema. A small-bore chest tube (< 20 F) should be tried first.
How can you distinguish between hydrothorax and pleural effusion?
When unspecified, the term “pleural effusion” normally refers to hydrothorax. A pleural effusion can also be compounded by a pneumothorax (accumulation of air in the pleural space), leading to a hydropneumothorax….

What are the 2 types of pleural effusion?

Is Hydrothorax and pleural effusion same?
Hepatic hydrothorax refers to the presence of a pleural effusion (usually >500 mL) in a patient with cirrhosis who does not have other reasons to have a pleural effusion (eg, cardiac, pulmonary, or pleural disease) [1-3]. Hepatic hydrothorax occurs in approximately 5 to 15 percent of patients with cirrhosis.
What is Hydrothorax meaning?
Hydrothorax is a noninflammatory collection of serous fluid within the pleural cavities. The effusion is clear and straw colored. Hydrothorax is unilateral or bilateral. The most common cause of hydrothorax is cardiac failure, but it is also frequently the result of renal failure and cirrhosis of the liver.
