The pleura is a very important tissue of the human body, as we all know, many organs have a layer of envelope, which plays a role in protecting the organs from bacteria, such as the pleura outside the lungs, the heart has pericardium protection, the brain has meningeal protection, the liver has liver envelope protection, when bacteria enter the human body before infecting these organs, the envelope has blocked a wave of attacks for these organs.
Today to talk about dry pleurisy, some people say why is it called dry, is it difficult to be wet? Really, just say right, although there is no term for wet pleurisy, but the corresponding diseases everyone must be more familiar with, that is, pleural effusion, the most common causes of pleural effusion are tuberculosis, tumors and heart, liver, kidney and other lesions, I have talked about many of this disease before, and today I mainly talk about dry pleurisy.
Most of dry pleurisy is caused by tuberculosis infection, so some people will ask, doesn't the above say that tuberculosis is the most common cause of pleural effusion? How can dry pleurisy also be caused by tuberculosis infection? In fact, the most common cause of dry pleurisy is tuberculosis infection.
Tuberculosis infection can produce a variety of symptoms, such as fever, night sweats, cough, sputum production, chest tightness, chest pain, dry pleurisy will basically have the above symptoms, especially chest pain, this pain occurs in the rib area of the person, the pain is severe, and sometimes even rolling on the ground. Why is pleurisy so painful, but pleurisy is different?
This is because the lungs do not have pain nerves, pain nerves are concentrated on the two layers of pleura outside the lungs, the pleura is usually thin and two layers of paper, but the nerves on the top are not many, slightly touch will be sensitive very much, we sometimes do punctures, puncture the pleura must be very careful, because some people will be punctured by the needle to faint, and even shock performance, blood pressure drop, pale face.
Dry pleurisy in addition to pain, another more prominent symptom is fever, body temperature is generally low-grade fever, but there are also high fever, many patients are low-grade fever in the afternoon, gradually fever to night, the morning can be self-deferting, may also continue, fever is more serious can lead to patient bedridden.
Most of the dry pleurisy is a transitional period, many dry pleurisy will occur when the pleural fluid can not be treated into a pleural effusion, when the patient's immunity is low, there will even be tuberculous empyema, that is, suppuration in the chest cavity, then it is relatively difficult to treat.
Since it is caused by tuberculosis bacteria, the diagnosis should try to seek the basis of tuberculosis infection, such as blood sampling for QFT examination, PPD experiments on the wrist area, most of the dry pleurisy can not be clearly diagnosed by etiology, sometimes it is necessary to do pleural biopsy to confirm the diagnosis, if the necrotizing granuloma can be clearly diagnosed in the pleura.
Tuberculous pleurisy, whether dry, pleural effusion or empyema, must be treated with a complete course of anti-tuberculosis therapy, generally requiring oral anti-tuberculosis drugs for more than 12 months.
