RESUMEN
BACKGROUND: The effectiveness of intravenous tranexamic acid (TA) in reducing blood loss and transfusion requirements during total hip replacement (THR) is well recognised. The aim of this study was to assess the effectiveness of a fibrin sealant in comparison to intravenous TA and a control group. PATIENTS AND METHODS: We prospectively studied 273 patients with primary hip osteoarthritis who underwent a THR between February 2012 and September 2013. The first 73 patients acted as the control group. The next 100 consecutive patients received fibrin sealant spray, and the last 100 patients received 1 g TA on induction. RESULTS: The demographic characteristics, surgical time, surgeon grade, anaesthetic type and pre-operative haemoglobin of the three groups were comparable. Both fibrin sealant and intravenous TA were effective in reducing blood loss during THR (15%, p = 0.04 and 22.5%, p = 0.01, respectively), when compared to the control group. However, neither treatment was found to be superior to the other in preventing blood loss p = 0.39. Tranexamic acid was superior to fibrin sealant in decreasing allogeneic transfusion requirements (0 vs. 10%, p = 0.05). There was no significant difference between the groups with regard to proportion of patients with wound leaking problems. CONCLUSION: Both fibrin sealant and intravenous tranexamic acid were effective in reducing blood loss. However, tranexamic acid use reduced post-operative transfusion requirements.
