Enoxaparin is a low-molecular-weight heparin used to prevent DVT and pulmonary embolism (PE).The refusal of enoxaparin significantly increases the patient's risk of developing DVT or PE.Normal platelet count is 150,000 to 400,000/mm³ so the patient with a 45,000/mm³ platelet count is at risk of hemorrhage.Bowel movement and transfusion do not increase risk of DVT or PE.
