Effect of different types of anticoagulants in the prevention of venous thrombosis in the operation of knee joint bone operation

Abstract

Deep venous thrombosis is one of the common complications after major surgery in the Department of Orthopedics. The selective knee replacement of the lower extremities is more likely to cause the occurrence of DVT. The most commonly used anticoagulants in the Department of Orthopedics now include low molecular weight heparin (LMWH), Rivaroxaban, ordinary heparin, aspirin and warfarin. At present, the clinical application of low molecular weight heparin is the most, and the effect is the most accurate. This study compared the efficacy and safety of three commonly used anticoagulants such as aspirin, LMWH and Rivaroxaban in preventing VTE after hip and knee arthroplasty, so as to provide a theoretical basis for selecting suitable anticoagulant drugs in clinic. It has been proved that LMWH has good efficacy and safety in the prevention of VTE after hip and knee arthroplasty and is a priority anticoagulant. Rivaroxaban can effectively control the occurrence of DVT and the drug is convenient, but it will increase the risk of bleeding and should be used carefully.
