Purulent pericarditis is a common disease in our country, encountered about 30-50% in pericarditis in children. Children with empyema can lead to cardiac tamponade and death if not diagnosed and treated early.

Acute pericardial effusion is a rare disease, the frequency of which is only about 0.1% of the total number of hospitalized patients and about 5% of the total number of patients admitted to the emergency room because of chest pain. However, this is a very dangerous disease, so timely emergency pericardial effusion will help patients have a better prognosis.

Pericardiocentesis is used in cases where the patient has pericardial effusion, which affects the heart function. This technique will help to drain the pericardial fluid so that the heart can restore its function, avoiding further accumulation of fluid in the pericardial sac.

Empyema pericarditis is a bacterial infection of the pericardial cavity. The disease progresses from infectious pericarditis to empyema pericarditis, which, if not treated promptly, becomes constrictive pericarditis.
