STS/SCA/AmSECT/SABM update to the clinical practice guidelines on patient blood management. Yu CC, Fidai M, Washington T, Bartol S, Graziano G. Oral is as effective as intravenous tranexamic acid at reducing blood loss in thoracolumbar spinal fusions: a prospective randomized trial. Recent meta-analyses indicate that prophylactic TXA is associated with less blood loss and a reduced likelihood of blood transfusion compared with placebo, with no concomitant increased risk of venous or arterial thrombosis.6470 However, the robustness of pooled data from randomized studies in these meta-analyses has been questioned because of inadequate reporting of prespecified outcomes and potential bias from inadequate blinding and randomization, data inconsistencies, and potential plagiarism.71 In addition, these meta-analyses report relatively modest mean reductions in blood loss with TXA versus placebo ranging from 65 to 160 mL, which may be of limited clinical significance. Routine antifibrinolytic use with TXA is well-established and strongly recommended in guidelines in cardiac surgery for reducing blood loss and allogeneic transfusion. Tranexamic acid (TXA) is widely accepted as an effective method for reducing blood loss after total knee arthroplasty (TKA). No increased risk of venous thrombosis or myocardial infarction was observed in those patients who received TXA.106 However, in the absence of a large prospective randomized-controlled trial, the potential risk of thrombosis must be weighed against the benefit of minimizing blood loss in each patient at high thrombosis risk (eg, patients with recent coronary artery stents, recent stroke, or hypercoagulability). 19.WHO. 2002;97:771778. Lancet. In obstetrics, TXA is associated with a reduced risk of mortality from PPH in predominantly under-resourced countries, but it is unclear whether it may reduce the risk of morbidity from PPH in well-resourced countries. 2018;85:851857.

Eastin TR, Snipes CD, Seupaul RA. Accumulating evidence suggests that TXA can reduce bleeding and transfusion in a variety of neurosurgery settings. Treating 4 AIS patients prevented 1 from blood loss of >20 mL/kg, and treating 9 AIS patients prevented 1 from receiving an allogeneic transfusion.141. 84. This medicine may be used by teenage females, but is not intended for use 17 popular meanings of TXA abbreviation: 25 89. In this randomized, placebo-controlled, phase 3 superiority trial, TXA did result in fewer deaths by day 7 compared to placebo, but functional status and mortality at 90 days were not different between the groups.126, The use of TXA in spine surgery has shown a larger benefit.127130 A recent summary of outcomes found that TXA reduced intraoperative, postoperative, and total blood loss, with variable reduction in RBC transfusion and no clear signal for prothrombotic complications.15 Another meta-analysis of topical TXA in spine surgery also found reduced blood loss with favorable effects on postoperative hemoglobin and no increase in deep vein thrombosis and pulmonary embolism.131 However, care is advised in using topical TXA for spine surgery since its packaging may resemble that of bupivacaine, and inadvertent intrathecal administration of TXA can produce myoclonus, seizure, paraplegia, arrhythmias, and death.41,132.

In a separate study, the Tranexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery (TRAAP2) study, 4551 women who underwent cesarean delivery were recruited.75 In TRAAP2, PPH was classified differently: a calculated (not measured) blood loss >1000 mL or an allogeneic RBC transfusion within 2 days of delivery.

Using pharmacokinetic modeling and simulation, a dosing regimen of 10- to 30-mg/kg loading dose (maximum 2 grams) and 5- to 10-mg/kg/h maintenance infusion rate to maintain TXA plasma concentrations in the 20- to 70-mcg/mL range may be considered as a target for pediatric trauma and cardiac and noncardiac surgeries.16 TXA dosing in cardiac surgery has unique concerns taking into consideration the targeted plasma concentration, the patients age (with higher doses for neonates and infants), and TXA added to the cardiopulmonary bypass circuit prime.17,18 Obtaining maximal efficacy and minimal side effects with these dosage regimens (as well as determining the ideal target plasma concentration) remains an area of ongoing investigation that will require larger prospective trials.

Given the null finding of the TRAAP1 study, the mixed findings of the TRAAP2 study, and the low quality of prior studies examining TXA for PPH prevention, current data are, at best, equivocal for justifying routine TXA administration for PPH prophylaxis before vaginal or cesarean delivery. Simultaneous with improved understanding of fibrinolysis in trauma patients, subsequent data found a less frequent benefit of TXA use.
