Abstract:

BACKGROUND: Tranexamic acid can effectively reduce the blood loss of total knee or hip arthroplasties. Tranexamic acid can be administered in a variety of ways; however, there is still much controversy about the best use of tranexamic acid.

OBJECTIVE: To compare the efficacy and safety between oral and intravenous tranexamic acid for blood loss after total knee and hip arthroplasties.

METHODS: Randomized controlled trials concerning oral tranexamic acid and intravenous tranexamic acid for reducing blood loss after total knee and hip arthroplasties were retrieved from PubMed, Cochrane Library, Embase and Web of Science databases from inception to May 2019. The data were extracted for the methodological quality. Then meta-analysis was conducted by Revman 5.3 software.

RESULTS AND CONCLUSION: Nine randomized controlled trials involving 1 080 cases were included. The results of this meta-analysis showed that there were no significant differences in total blood loss [MD=1.43, 95%CI(-40.02-42.88), P=0.95], postoperative hemoglobin decline [MD=-0.03, 95%CI(-0.11-0.05), P=0.45], transfusion rate [RR=0.91, 95%CI(0.55-1.49), P=0.70], deep vein thrombosis rate[RR=0.43, 95%CI(0.11-1.64), P=0.22], or hospitalization time [MD=0.00, 95%CI(-0.03-0.03), P=0.93] between two groups. These results indicate that oral tranexamic acid shows comparable efficacy to that of the intravenous forms after total knee and hip arthroplasties. However, due to the low number and limited quality of included studies, more randomized controlled trials with large samples should be rigorously designed to verify the conclusion.
