2. Management of pulmonary infarction

2.1. Management of large-scale pulmonary infarction with hemodynamic disturbances ● Intensive resuscitation, comprehensive and accurate assessment of the patient's hemodynamic status.
● Treatment of cardiogenic shock: make sure the fluid is filled with macromolecular fluids.
● Treatment of myocardial contractility: Using drugs to enhance myocardial contractility, in case blood pressure cannot be increased, vasopressors should be used.
● Treatment of acute respiratory failure: high-volume oxygen breathing through a nasal cannula or through a mask.
● Treatment of fibrinolysis: Indications for severe pulmonary infarction; Pulmonary infarction is hemodynamically stable but with echocardiographic signs of acute bronchiectasis.

2.2. Management of pulmonary infarction without hemodynamic disturbances Treatment is aimed at preventing the spread of pulmonary infarction, facilitating clot lysis and clearing the infarct. Specifically:
● Heparin therapy: This is the first basic treatment for patients with pulmonary infarction. Regular intravenous heparin or subcutaneous low molecular weight heparin can be administered.
● Venous membrane filter: Indicated for patients with pleural infarction with deep vein thrombosis of the lower extremities spreading into the vena cava, strong mobile thrombus tail; deep vein thrombosis of the lower extremities causing repeated pulmonary infarction; DVT has recently formed, but the patient needs to discontinue anticoagulation for another medical condition or has a current contraindication to anticoagulation.
