Abstract:

BACKGROUND: Rivaroxaban and enoxaparin are commonly used drugs to prevent venous thromboembolism after total hip arthroplasty. There is still some controversy on the safety and efficacy. At present, there is no research on the optimal dose of rivaroxaban in domestic and foreign countries.

OBJECTIVE: To systematically review the protective effect and safety for prevention of venous thromboembolism after total hip arthroplasty between rivaroxaban and enoxaparin.
METHODS: Databases were retrieved including The Cochrane Library (Issue 9, 2014), Medline, EMbase, PubMed, VIP, WanFang and CNKI (from database foundation to September 2015) for randomized controlled trials about rivaroxaban compared with enoxaparin to prevent venous thromboembolism after total hip arthroplasty. Meta-analysis was conducted in two kinds of treatment of deep vein thrombosis, major venous thromboembolism, major bleeding events, non-major bleeding and minor bleeding events.
RESULTS AND CONCLUSION: (1) Overall results showed that: efficacy of rivaroxaban was better than enoxaparin in the prevention of venous thromboembolism after total hip arthroplasty, but rivaroxaban has greater risk for hemorrhage. (2) Subgroup analysis results demonstrated that the efficacy of rivaroxaban at 10 and 30 mg/d was better than that of enoxaparin in the prevention of venous thromboembolism (P < 0.05). The efficacy of rivaroxaban at 10 mg/d was better than that of enoxaparin in the prevention of venous thromboembolism (P < 0.05). The risk of hemorrhage when using rivaroxaban at 30, 40 and 60 mg/d was higher than that of enoxaparin (P < 0.05). (3) Comprehensive subgroup analysis results showed that the efficacy and safety of rivaroxaban at 10 mg/d were better than enoxaparin. (4) Due to the limited quantity and quality of included studies, these conclusions need more high-quality and large multicenter randomized controlled trials to verify.
