The combination of pneumonia and pleurisy called pleuropneumonia. Disease often begins in pneumonitis (pneumonia), and pleural effusion is a complication of the process. Most often it develops at pleuropneumonia of pneumonia
Lobar pneumonia - severe course of the disease
, Caused by Streptococcus pneumoniae.
How to start pleuropneumonia
Pleuropneumonia begins with a sharp decline in immunity after exposure to cold, very high physical exertion or stress. This conditionally pathogenic (particularly Streptococcus pneumoniae, which often dwells in the upper respiratory tract) is able to overcome the barrier of the mucous membrane of the alveoli and small airways and penetrate into its surface layers, causing inflammation.
The disease begins with the fact that the pneumococcus, hitting into the alveoli, releases a toxin that causes a sharp rush of blood to the entire lobe of the lung, in the region that have implemented the pathogen and tissue edema. At the same time affected and adjacent to the affected lobe of the lung pleura. Step edema lasts twelve hours to three days.
In the next phase the alveoli are filled with blood vessels propotevayuschey of liquid protein-rich fibrin, then come to the red blood cells from the bloodstream (they cause staining of lung tissue in red - red hepatization that lasts well for about three days). Fibrin and falls in the pleura - developing fibrinous pleurisy.
The next step in the alveoli rush leukocytes (gray hepatization) that contribute to the resorption of fluid - begins a gradual process of recovery. Fibrin falls in the form of films, which are then absorbed in the help enzymes secreted by white blood cells - begins the healing process.
Since the inflammatory process involved large areas of the lung is affected and adjacent pleura - serous double skin covering the lungs.
Symptoms
Pleuropneumonia begins suddenly, and all stages of the disease correspond to changes that occur in the lungs and pleura. After exposure to a factor contributing to the sudden sharp decline in immunity. The patient has high fever (up to 40-41 ° C), it is shaking chills, after a while there are strong pains in his side on the affected side. Such pain suggests involvement in the pathological process of the pleura, which is full of nerve endings. The pain is so severe that the patient tries to breathe surface: a deep breath can lead to loss of consciousness. Small dry cough
Dry cough - whether to worry about it?
as the surface - much coughing impossible because of the pain.
Characteristic blush on one cheek on the affected side, there is a "cold" on the lips (herpes simplex - this agent also does not miss his chance at a lowered immunity). Frequent shallow breathing causes cyanosis nasolabial triangle, ears and fingertips, the rest pale skin.
If affects the lower lobes of the lungs, the pleura is inflamed, covering the aperture (horizontal muscle that separates the chest cavity from the abdominal), and there are severe abdominal pain
Abdominal pain: Types and Symptoms
. In this regard, the patient is sometimes diagnosed with acute abdomen, even some patients with this diagnosis is sent to the surgical department of a hospital.
After a period the red light comes, and then white hepatization, the patient starts to cough phlegm brownish color ("rusting").
What the doctor discovers during the inspection of the patient
If you look closely to the chest of the patient, we can see that one side of it is behind by breathing on it as you can see retraction intercostal spaces.
On examination, the doctor can detect changes rapping sound (percussion) chest. The sound initially, in step tympanic edema is (are alveolar air and liquid). With phonendoscope at that time listened characteristic crackling (crackling) - is razlipayutsya inspiratory matted alveoli.
In the phase of red and gray hepatization when the alveoli completely filled with liquid, fibrin and cellular elements, percussion over the zone of destruction is heard a dull sound, and auscultation - no wheezing. The phase resolution process reappear crepitus
Crepitus - a very serious symptom
and tympanic sound above the zone of destruction. If the small bronchi is a liquid, it can be heard as finely moist rales, but they are not always. With a large number of fibrinous deposits on the pleura can be heard as pleural rub.
Pleuropneumonia - it is a serious illness that is treated only in a hospital. Before the advent of antibiotics in our lives, most patients died pleuropneumonia from complications of the disease on the part of the cardiovascular system and brain.
