摘要
The aim of the present study was to evaluate the efficacy of topical versus combined (intravenous + topical) tranexamic acid (TXA) to reduce perioperative blood loss after uncemented primary total hip arthroplasty (THA). Seventy-five patients were randomized in three comparable experimental groups: 1) topical TXA (3 g in 50 ml of saline solution); 2) intravenous + topical TXA (3 g topical + 2 g in 100 ml of saline solution intravenously); 3) controls. Pre- and post-operative hemoglobin (Hb) levels and hematocrit (Hct) values along with the rate of blood transfusion in the 3 groups were compared. The intravenous + topical TXA group demonstrated higher Hb levels and Hct values at postoperative day one (Hb = p <0.05, Hct = p <0.001), postoperative day three (Hb = p <0.05, Hct = p <0.001), and discharge (Hct = p <0.01) compared to the control group. The intravenous + topical group had a lower transfusion rate compared to the control group (0% vs 20%, p = 0.014). With the numbers available, no difference in postoperative Hb level and transfusion rate emerged between topical TXA and control group.
