Objectives

Narrative objectives1

Tranexamic acid (TXA) has been used to reduce perioperative bleeding in various surgery because of its antifibrinolytic effect. Recently, the patients undergoing spine surgery in our hospital received a loading dose of TXA (1000 mg) before surgery followed by 100 mg/hour until the end of surgery. The purpose of this retrospective study is to evaluate the efficacy of TXA administration on the perioperative blood loss in patients undergoing spine surgery. Secondary outcome is the correlation between the estimated plasma cincentration of TXA and perioperative blood loss.

Results

A total of 212 patients underwent surgery. Propensity score matching yielded 62 patients each in the TXA and no TXA groups. Perioperative blood loss did not differ significantly, but delta Hb was significantly lower in the TXA group. Maximum TXA concentration showed no correlation with perioperative blood loss or transfusion volume. TXA concentration at the end of surgery was negatively correlated with perioperative blood loss and transfusion volume.
