What is the recommended DVT (Deep Vein Thrombosis) prophylaxis regimen for patients undergoing ORIF (Open Reduction Internal Fixation) surgery, considering individual risk factors such as impaired renal function and bleeding history?

From the Guidelines

Xarelto (rivaroxaban) can be used for DVT prophylaxis in patients undergoing ORIF surgery, but its use should be individualized based on patient risk factors, with a recommended dose of 10 mg orally once daily, as suggested by the study 1. For patients with impaired renal function, dose adjustment may be necessary, and for those with a high bleeding risk, alternative prophylaxis methods such as mechanical prophylaxis using intermittent pneumatic compression devices or graduated compression stockings may be considered. The decision to use Xarelto or other anticoagulants should be based on the patient's individual risk factors, including renal function, bleeding history, and procedure complexity, as well as the latest clinical guidelines, such as those from the American College of Chest Physicians 1 and the American Society of Clinical Oncology 1. Prophylaxis typically begins 12-24 hours after surgery when hemostasis is established and continues until the patient is fully mobile, usually 10-35 days depending on risk factors and procedure complexity. Early mobilization should complement pharmacological or mechanical prophylaxis for all patients, as it helps to reduce the risk of DVT and improve overall outcomes, as recommended by the study 1. In high-risk patients, extended prophylaxis may be warranted, and the use of Xarelto or other anticoagulants should be carefully monitored to minimize the risk of bleeding complications, as suggested by the study 1. The management of direct oral anticoagulants, including Xarelto, in patients undergoing elective surgeries and invasive procedures should follow updated guidelines, such as those from the French Working Group on Perioperative Hemostasis (GIHP) 1. Overall, the use of Xarelto for DVT prophylaxis in ORIF surgery patients should be tailored to the individual patient's needs and risk factors, and should be guided by the latest clinical evidence and guidelines.

DVT Prophylaxis Regimen for Patients Undergoing ORIF Surgery

The recommended DVT prophylaxis regimen for patients undergoing ORIF surgery should consider individual risk factors such as impaired renal function and bleeding history.

• The use of rivaroxaban (Xarelto) has been studied in several clinical trials, including those for patients with normal renal function and those with impaired renal function 2, 3.
• Rivaroxaban has been shown to be effective in preventing postoperative VTE in patients undergoing major orthopedic surgery, including ORIF surgery 2, 4.
• For patients with impaired renal function, the use of rivaroxaban may be associated with a lower risk of major bleeding compared to enoxaparin/VKA therapy 3.
• The dosage of rivaroxaban for DVT prophylaxis is typically 10 mg once daily, although the dosage may need to be adjusted for patients with severe renal impairment 2, 3.
• Enoxaparin 20 mg daily has also been evaluated for thromboprophylaxis in patients with severe renal impairment, with a reported incidence of VTE of 5.6% and major bleeding events of 10% 5.
• Fondaparinux has also been compared to rivaroxaban in patients undergoing major orthopedic surgery, with rivaroxaban showing superior efficacy and safety 4.

Considerations for Individual Risk Factors

• Impaired renal function: Rivaroxaban may be a suitable option for patients with impaired renal function, as it has been shown to be effective and safe in this population 3.
• Bleeding history: Patients with a history of bleeding may require closer monitoring and adjustment of their anticoagulant therapy, with rivaroxaban potentially being a suitable option due to its lower risk of major bleeding compared to enoxaparin/VKA therapy 3, 6.
• Cancer: Rivaroxaban has been evaluated in patients with cancer and VTE, with similar efficacy to enoxaparin/VKA therapy and a reduced risk of major bleeding 6.

Summary of Key Findings

• Rivaroxaban is an effective and safe option for DVT prophylaxis in patients undergoing ORIF surgery, including those with impaired renal function and bleeding history 2, 3, 4, 6.
• The dosage of rivaroxaban should be adjusted according to individual risk factors, such as severe renal impairment 2, 3.
• Enoxaparin 20 mg daily and fondaparinux are alternative options for thromboprophylaxis in patients with severe renal impairment and those undergoing major orthopedic surgery, respectively 5, 4.
