What exactly is bloody pleural effusion?

I believe that many people must have suffered from traumatic diseases in their lives. However, after the trauma, if you do not pay attention to care, the ordinary epidermis will begin to become edematous, red and swollen, and severe cases will cause blisters. Therefore, trauma requires timely care, but many people will need chest puncture due to lung cancer or chest trauma. This method is used to remove the pleural effusion, which will form bloody pleural effusion. This symptom is very common and most of the time it is caused by trauma. As long as it does not metastasize, you can take reasonable measures to prevent it, find the cause of the disease, and then choose the appropriate treatment plan according to the pathological type to avoid the formation of lymphoma or chest cysts that will cause the disease to metastasize, which will cause great harm to the body.

Overview

Because of lung cancer or chest trauma, patients need to undergo thoracentesis. Generally speaking, this method can extract pleural effusion, thus becoming bloody pleural effusion. Some patients may feel particularly scared. Let's talk about whether bloody pleural effusion is very red.

Is bloody pleural effusion very red?

First: The hematocrit of bloody pleural effusion > 50% indicates hemothorax. It is more common in trauma, and occasionally in spontaneous pneumothorax, aortic aneurysm rupture, pleural metastasis, pleural mesothelioma, blood disease, anthrax pleurisy, paragonimiasis, connective tissue disease, tuberculous pleurisy, etc. Pleural effusion can be divided into exudative and transudative types based on its nature. There are many causes of exudative diseases.

Second: Most are exudative, and a few are bloody pleural effusions. The lesions cause pleuritic infiltration, which increases vascular permeability, capillary hyperplasia and bleeding, or tuberculous nodules directly cause vascular wall necrosis or vascular rupture and bleeding. Trauma including aortic aneurysm rupture, esophageal rupture, etc. cause massive bleeding, which enters the pleural cavity and causes hemorrhagic pleural effusion.

Third: About 40% of pancreatic pleural effusions are bloody, which is caused by internal bleeding in the pseudocyst. Pleural effusions in chronic alcoholic pancreatitis may also be bloody. Spontaneous pneumothorax can cause rupture of blood vessels in the pleural adhesion zone, resulting in hemothorax. Hemorrhagic pleural effusion is very common in malignant tumors, with lung cancer accounting for 4.2%, followed by breast cancer, lymphoma and other tumor pleural metastasis.

Precautions

Through the simple introduction above, we have also gained a corresponding understanding of thoracentesis, and the color of the extracted pleural effusion is also particularly red. After all, this is also a kind of blood. In order to avoid this phenomenon, patients should pay attention to protecting themselves and undergo regular physical examinations.
