Abstract:

BACKGROUND: Direct factor Xa inhibitors play an important role in the prevention and treatment of venous thromboembolism. However, the efficacy and safety of direct factor Xa inhibitors in the prevention of venous thromboembolism in the patients that undergoing total knee arthroplasty is not clear when compared with the low-molecular-weight heparin.
OBJECTIVE: To explore the pros and cons of direct factor Xa inhibitor and low-molecular-weight heparin in the prevention of deep venous thromboembolism after total knee arthroplasty.
METHODS: A computer-based online search was performed in MEDLINE database, EMBASE database, Cochrane Library, CBM database and CNKI database, supplemented by manual searches to find the randomized trials on the comparison of direct factor Xa inhibitor and low-molecular-weight heparin in the prevention of deep venous thromboembolism after total knee arthroplasty. The quality of included studies was evaluated by quality assessment standards proposed by the Cochrane Handbook, and data analysis was performed with Stata12.0 software.
RESULTS AND CONCLUSION: Compared with low-molecular-weight heparin, direct factor Xa inhibitor can significantly reduce the incidence of symptomatic deep venous thromboembolism without increasing bleeding risk (P < 0.05), and there were no significant differences in mortality rate during follow-up period and pulmonary embolism between two groups (P > 0.05). In the prevention of deep venous thromboembolism after total knee arthroplasty, direct factor Xa inhibitor is more secure, effective and convenient than low-molecular-weight heparin.
