If a patient presents with pericardial effusion, normally the trachea is displaced laterally, but specific circumstances can determine this. For minor or moderate amounts of pericardial effusion, the current treatment primarily involves pericardiocentesis to drain the fluid; symptomatic treatment is predominantly used. During this period, it is also important to monitor changes in the patient's heart rate, blood pressure, and pulse. If the patient experiences a rapid heart rate and increased blood pressure, these conditions need to be actively managed. Early use of cardiotonic diuretics can help alleviate respiratory distress, wheezing, or shortness of breath after activity caused by the pericardial effusion. Regular cardiac echocardiography check-ups are also recommended for the patient.
