The treatment of pericardial effusion mainly includes the following measures:

First, treatment should be based on the different causes of pericardial effusion. For example, pericardial effusion caused by infection should be treated with anti-infection measures, and pericardial effusion caused by heart failure should be treated with anti-heart failure measures;

Second, for a large amount of pericardial effusion or pericardial effusion causing cardiac tamponade, active pericardiocentesis and drainage should be provided to relieve the pressure on the heart caused by the pericardial effusion;

Third, when severe pericardial effusion causes hypotension or even shock, volume expansion and pressor agents should also be administered;

Fourth, for some patients with pericardial effusion, if the absorption of the effusion is not effective after general treatment, corticosteroids may be appropriately administered.
