    ObjectiveTranexamic acid (TXA) significantly reduces the visible and hidden blood loss associated with joint replacement. At present, many studies have examined the safety and effectiveness of the intravenous or topical administration of TXA after posterior lumbar surgery. However, randomized and controlled trials examining the presence of differences in the effect of TXA on the visible and hidden blood loss between these 2 modes of administration are lacking. The current study investigated the effects of intravenous and topical administrations of TXA on the visible and hidden blood loss of patients undergoing posterior lumbar interbody fusion (PLIF).MethodsIn a single-center, placebo-controlled, randomized design, a total of 150 patients with lumbar degenerative disease who underwent PLIF between September 2015 and August 2017 volunteered for this study. Of these patients, 126 fulfilled the inclusion criteria and were randomly assigned to 1 of 3 groups: the intravenous administration group (n = 45, group A), the topical administration group (n = 39, group B), or the placebo group (n = 42, group C). SPSS, version 17.0, was used to analyze the patient data, their blood biochemical indices, blood loss, and the number of blood transfusions across the 3 groups during the perioperative period.ResultsThe postoperative drainage volume, number of blood transfusions, length of hospital stay, and extubation time significantly differed between group C and both groups A and B (P < 0.05); however, no significant differences were noted between groups A and B (P > 0.05). Intraoperative blood loss and visible or hidden blood loss as well as the levels of postoperative hemoglobin and hematocrit significantly differed among the 3 groups (P < 0.01). The results of the visual analogue scale, prothrombin time, and fibrinogen content did not significantly differ among the 3 groups (P > 0.05).ConclusionsFor patients undergoing double-segment PLIF, both administrations of TXA can reduce blood loss, extubation time, and the length of hospital stay. Moreover, intravenous administration can reduce both visible and hidden blood loss more efficiently.Copyright © 2018 Elsevier Inc. All rights reserved.
