Hi


Timing and duration of prophylactic agents has also been determined to have a significant effect the development of DVT. Early prophylaxis in surgical patients with LMWH has been associated with significant reductions in postoperative venous thrombosis. Studies have shown that initiation of therapy within 8 hours of surgery has the greatest effect . Additional recommendations by the ACCP for extended out-of-hospital prophylaxis have been made based on multiple randomized studies that have demonstrated an additional 7-10 days of anticoagulation decrease venous thrombosis rates WITHOUT major bleeding issues.

Good luck
