Tomo Riba Institute of Health and Medical DOI: https://doi.org/10.22271/ortho.2020.v6.i3b.2183 Sciences (TRIHMS), Arunachal Pradesh, India Abstract Background: Introduction: Total hip arthroplasty (THA) is a successful surgical procedure for reducing Dr. Moji Jini pain and improving physical function in osteoarthritis. It is one of the most effective orthopaedic Director, Tomo Riba Institute of procedures. Health and Medical Sciences, Material and methods: Patients were eligible for the study if they were aged 18 years or older and were Arunachal Pradesh, India scheduled for total hip arthroplasty. Patients were ineligible if they were scheduled to undergo staged, bilateral hip arthroplasty were pregnant or breastfeeding, had active bleeding or a high risk of bleeding, or any disorder contraindicating the use of Rivaroxaban/enoxaparin that might necessitate enoxaparin dose adjustment. Results: Of the 52 patients enrolled in study, 52 patients were randomized to receive either Rivaroxaban (n=26) or enoxaparin (n=26). The baseline demographic characteristics of the two randomized treatment groups are well balanced as described in Table 1. The surgical characteristics are described in Table 2. Conclusion: Rivaroxaban, given as a once-daily 10 mg fixed dose 6–8 h postoperatively, is the first new oral anticoagulant to significantly reduce the incidence of venous thromboembolism after total knee arthroplasty, compared with enoxaparin 30 mg twice daily, starting 12–24 h postoperatively, without a significant difference in the risk of major or clinically relevant bleeding.

  • LOW MOLECULAR WEIGHT HEPARIN and FONDAPARINUX Zachary Stacy and Sara K
    4 Chapter LOW MOLECULAR WEIGHT HEPARIN AND FONDAPARINUX Zachary Stacy and Sara K. Richter INTRODUCTION The low molecular weight heparins (LMWHs) and the synthetic pentasaccharide, fondaparinux, offer several advantages over unfractionated heparin (UFH). Enoxa- parin and dalteparin were approved in the United States in 1993 and 1994, respec- tively, followed by fondaparinux in 2001. Tinzaparin was approved and available in 2000, but was subsequently withdrawn from the market in 2011. These injectables have been traditionally used as prophylaxis for venous thromboembolism or as a bridge therapy to therapeutic oral anticoagulation. Based on their relative ease of dosing and monitoring, these agents frequently replace UFH in many clinical situations. This chapter will focus on those agents currently available in the United States, including enoxaparin, dalteparin, and fondaparinux. PHARMACOLOGY AND PHARMACOKINETICS1-9 Traditionally, unfractionated heparin was the parenteral anticoagulant used in the inpatient setting. Active unfractionated heparin compounds are composed of an inconsistent number of sugars, each ending in a specific pentasaccharide sequence. Using a consistent and shorter sequence of sugars improved the variability in the anticoagulant effect, giving rise to fractioned LMWH products. Mechanism of Action • LMWHs and fondaparinux are indirect inhibitors of clotting factors requiring antithrom- bin to exert an anticoagulant effect (Figure 4-1). • A specific pentasaccharide sequence binds to antithrombin to potentiate its activity. • LMWHs inhibit both Factor Xa and IIa (thrombin) activity. • Fondaparinux selectively inhibits only Factor Xa. • Refer to Tables 4-1 and 4-2 for comparison of the specific clotting factors inhibited. 65 66 Anticoagulation Therapy AT AT AT X a AT Thro mbin UFH AT AT X a AT Thro mbin LMWH Xa AT AT AT Throm bin Fondaparinux FIGURE 4-1.
