Bleeding in the lungs

Introduction Pulmonary hemorrhage may occur simultaneously with trauma or coagulopathy. Pulmonary contusions and hemorrhage are common after trauma. The congestion formed within 6 hours after the trauma. Symptoms worsened within 24 to 48 hours, and complete healing often occurred within 3 to 10 days. There may also be other symptoms of chest trauma, such as rib fractures. Clinical symptoms include difficulty breathing, shortness of breath, coughing and bleeding.

Cause

Pulmonary hemorrhage may occur simultaneously with trauma or coagulopathy. Pulmonary contusions and hemorrhage are common after trauma. The congestion formed within 6 hours after the trauma. Symptoms worsened within 24 to 48 hours, and complete healing often occurred within 3 to 10 days. There may also be other symptoms of chest trauma, such as rib fractures.

Pulmonary hemorrhage can occur with coagulopathy, such as coumarin poisoning (acetone benzyl hydroxycoumarin poisoning), von Willebrand's disease, heart worm disease (filariasis) or disseminated intravascular coagulation ( DIC). Pulmonary hemorrhage can be complicated by mediastinal and/or pleural hemorrhage or other parts of the chest.

an examination

Radiological examinations include pulmonary spaces or alveolar opacity, the distribution of which is uncertain. Radiological examination of the pleural and/or pleural effusions is also performed.

Differential diagnosis

The diagnosis should be differentiated from the following symptoms:

Increased pulmonary blood

Aortic valve insufficiency, usually asymptomatic, but once the disease, the disease progresses rapidly, the left heart bulge is caused by aortic valve insufficiency, the increase in pulmonary blood is due to high left ventricular pressure, causing high left atrial pressure, and then Causes lung stagnation.

2. Alveolar bleeding

Pulmonary hemorrhagic-nephritis syndrome is also known as anti-base glomerulonephritis, Goodpasture syndrome or Goodpasture disease. May be caused by viral infection and / or inhalation of certain chemical substances. It is a serious damage of the glomerular and alveolar wall basement membrane caused by anti-base membrane antibody, clinical manifestations of pulmonary hemorrhage, rapid glomerulonephritis and serum anti-glomerular basement membrane (GBM) antibody-positive triad. Most patients progress rapidly and the prognosis is dangerous.

3. Pulmonary congestion

Pulmonary congestion refers to the occurrence of blood deposits in the local blood vessels of the lungs, usually caused by left heart failure, increased pressure in the left heart chamber, obstructing pulmonary venous return, causing pulmonary congestion.
