Timing and duration of prophylactic agents has also been determined to have a significant effect on the development of DVT. Early prophylaxis in surgical patients with low molecular weight heparin has been associated with significant reductions in postoperative venous thrombosis. If surgery is delayed, then prophylaxis with low-dose unfractionated heparin or low molecular weight heparin should be initiated at the time of admission and discontinued prior to surgery.
