Two high quality (Martin et al, Niskanen et al) and two moderate strength (Imai et al, Benoni et al) studies evaluated the perioperative use of tranexamic acid (TXA) for total hip arthroplasty (THA). Martin, et al conducted a prospective, stratified, randomized, double-blind, placebo-controlled trial that demonstrated that the use of topical TXA in THA resulted in a smaller reduction in postoperative hemoglobin. There was a trend toward lower transfusion rates that was not statistically significant. Niskanen at el and Korkala et al conducted a randomized, double-blind study of 39 THA patients that demonstrated smaller total blood loss in cemented THA for patients who received perioperative intravenous TXA. Imai, et al evaluated 107 THA patients who were randomly divided into 1 control group and 4 treatment groups based on the timing of TXA administration. All groups who received TXA, irrespective of the dose timing, experienced lower intraoperative and perioperative total blood loss. Benoni et al, performed a prospective, randomized, double-blind study on the effect of intravenous TXA at the beginning of THA which also demonstrated significantly lower postoperative blood loss compared to placebo. Since indications for allogenic blood transfusions differed among studies, there was no consistent evidence that TXA reduced perioperative transfusion rates.
