Administration of enoxaparin 30 mg subcutaneously every 12 hours.
Low-molecular-weight heparin is most often recommended for deep venous thrombosis (DVT) prophylaxis in patients undergoing hip or knee replacement. Aspirin is not effective in preventing DVT in any situation. Elastic stockings and low-dose unfractionated heparin have minimal impact on the incidence of DVT in these patients. Similarly, warfarin protocols in patients with international normalized ratios less than 2 postoperatively will not greatly change DVT rates.
