What is the primary purpose of administering low molecular weight heparin (LMWH) post-surgery?

The primary purpose of administering low molecular weight heparin (LMWH) post-surgery is to prevent blood clot formation. After surgery, patients are at an increased risk for venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE). LMWH is an anticoagulant that works by inhibiting certain factors in the blood coagulation cascade, effectively reducing the ability of the blood to clot.

By minimizing the risk of blood clots, LMWH helps improve patient outcomes and enhances recovery after surgery. This is particularly important in surgical patients who may have restricted mobility, making them more susceptible to clot formation. Prophylaxis with LMWH is a standard practice in many surgical protocols to address this concern and ensure the safety of patients during the recovery period.
