Review Meta Analysis
Topical fibrin sealant versus intravenous tranexamic acid for reducing blood loss following total knee arthroplasty: A systematic review and meta-analysis.
Efficacy and safety of topical application of a fibrin sealant (FS) compared with intravenous administration of tranexamic acid (TXA) for reducing blood loss after total knee arthroplasty (TKA) is controversial. We undertook a meta-analysis to compare the effects of topical application of FS or intravenous administration of TXA on blood loss after TKA. ⋯ Our meta-analysis suggests that intravenous administration of TXA for patients undergoing TKA may reduce blood-transfusion requirements and maintain higher hemoglobin levels compared with topical application of FS in the early postoperative period. There were no significant differences in total calculated blood loss and prevalence of complications between the two groups. However, owing to the variation of included studies, no firm conclusions can be drawn.
