The present study is a multi-center randomized prospective non-inferiority trial. The study's primary objective is to compare the coagulation profile upon using two different TXA administration strategies: empirical TXA administration vs. viscoelastic test-based goal-directed TXA administration in high-risk non-cardiac surgery. The secondary objectives include comparing the amount of bleeding, incidents of hyper-fibrinolysis, thromboembolic complications, and postoperative seizures. Researchers assumed that goal-directed tranexamic acid (TXA) administration using viscoelastic field tests would not be inferior to the empirical TXA administration strategy in reducing postoperative bleeding and hyper-fibrinolysis. It also would be beneficial in lowering TXA-induced thromboembolic complications and seizures.

The present study is a multi-center randomized prospective placebo-controlled non-inferiority trial. This study's primary objective is to compare the coagulation profile upon using two different TXA administration strategies: empirical TXA administration vs. viscoelastic test-based goal-directed TXA administration in non-cardiac surgery. The secondary objectives include determining the inter-group differences in hyper-fibrinolysis, during postoperative 2bleeding, thromboembolic complications, and postoperative seizures. Researchers hypothesized that goal-directed TXA administration using viscoelastic field tests would not be inferior to the empirical TXA administration strategy in reducing postoperative bleeding and hyper-fibrinolysis. Researchers also expect that goal-directed TXA administration would be beneficial in lowering TXA-induced thromboembolic complications and seizure risks.

At initiation of surgical preparation, participants randomized to the active treatment arm will receive tranexamic acid 10 mg/kg (max 1 g), given via syringe pump programmed to infuse over 15 minutes. If no unacceptable toxicities occur, a second dose of tranexamic acid IV push over 5 to 15 minutes will be given 6 hours (with a window of +/- 30 minutes) after the first dose (either intra- or post-operatively).

At initiation of surgical preparation, participants randomized to the placebo treatment arm will receive 0.9% sodium chloride (salt water). It will be matched in appearance, volume, and administration to the active treatment arm with tranexamic acid. If no unacceptable toxicities occur, a second dose of placebo IV push over 5 to 15 minutes will be given 6 hours (with a window of +/- 30 minutes) after the first dose (either intra- or post-operatively).

This is a randomized double-blind control trial evaluating the use Tranexamic acid (TXA) to decrease blood loss and transfusion requirements in pediatric and young adult cancer patients undergoing a limb salvage procedure that frequently requires perioperative or post-operative transfusions of blood products.

Primary Objective

* To evaluate the difference in intra-or post-operatively transfused blood volume (mL/kg) for patients undergoing limb salvage procedures of the distal femur or proximal tibia who are randomized to receive perioperative tranexamic acid (TXA) versus placebo.

Secondary Objectives

* To evaluate changes in platelets and in hemoglobin from pre-op to post-op level for patients randomized to receive perioperative TXA versus placebo.
* To evaluate differences in post-operative daily surgical drain output for patients randomized to receive perioperative TXA versus placebo.
* To evaluate changes in estimated blood loss (EBL) for patients randomized to receive perioperative TXA versus placebo.
* To evaluate the association between the intra-or post-operatively transfused blood volume and estimated blood loss (EBL) for patients randomized to receive perioperative TXA and placebo, respectively.

Exploratory Objectives

* To evaluate differences in functional outcomes post-operatively for patients randomized to receive perioperative TXA versus placebo.
* To explore if significant correlations are observed between parameters reported with rotational thromboelastometry (ROTEM®) and EBL and transfusion requirements in pediatric and young adult patients undergoing limb salvage procedure who are randomized to perioperative TXA versus placebo.
* To evaluate differences in the prevalence and management of wound complications such as superficial or periprosthetic infections, wound dehiscence, contact dermatitis, post- operative hematomas, or any other clinically significant wound complication between patients randomized to receive perioperative TXA versus placebo.

Eligible participants undergoing limb salvage procedures will be randomized to receive either tranexamic acid (TXA) or placebo peri-operatively.

The initial dose of tranexamic acid/placebo will be given at the initiation of surgical preparation. The second dose will be given 6 hours after the first dose (either intraoperatively or post-operatively). All doses will be given intravenously. Doses will be double blinded and randomized for each surgical procedure.

To allow for the study team and participants to remain blinded to the treatment assignment, the study drug will be labeled as Tranexamic Acid/Placebo (TXAKIDS) followed by applicable dose and administration instructions.

Individual participant de-identified datasets containing the variables analyzed in the published article will be made available (related to the study primary or secondary objectives contained in the publication). Supporting documents such as the protocol, statistical analyses plan, and informed consent are available through the CTG website for the specific study. Data used to generate the published article will be made available at the time of article publication. Investigators who seek access to individual level de-identified data will contact the computing team in the Department of Biostatistics (ClinTrialDataRequest@stjude.org) who will respond to the data request.

The intra-operative volumes of transfused blood for both the TXA treated group and placebo group will be estimated with a two-sided 95% confidence interval. The blood volumes transfused per kilogram of body weight of the two groups (TXA vs. Placebo) will be evaluated using a two-sided student's t-test after log(1+x) transformation.

The post-operative volumes of transfused blood for both the TXA treated group and placebo group will be estimated with a two-sided 95% confidence interval. The blood volumes transfused per kilogram of body weight of the two groups (TXA vs. Placebo) will be evaluated using a two-sided student's t-test after log(1+x) transformation.

Summary statistics will be provided for the changes in platelet level from pre-op to post-op level, for both the TXA and placebo group. Two sample t-test or Wilcoxon rank sum test will be used to compare the differences between the two groups. Multiple comparison correction might be used for p-values to address the multiple testing issues due to measurements at multiple time points.

Summary statistics will be provided for the decline in hemoglobin from pre-op to post-op level, for both the TXA and placebo group. Two sample t-test or Wilcoxon rank sum test will be used to compare the differences between the two groups. Multiple comparison correction might be used for p-values to address the multiple testing issues due to measurements at multiple time points.

Summary statistics will be provided for postoperative daily surgical drain output (in milliliters per 24 hour period for the duration of the drain) for each group. The group difference will be compared using two-sample t-test or Wilcoxon rank sum test depending on the distribution of the observed data. Multiple comparison correction might be used for p-values to address the multiple testing issues due to measurements at multiple time points.

The EBL for pre-op to post-op level, for both the TXA treated group and placebo group will be estimated with a two-sided 95% confidence interval. The EBL of the two groups (TXA vs. Placebo) will be evaluated using a two-sample t-test or Wilcoxon rank sum test depending on the distribution of the observed data.

Regression model will be used to access the correlation between the log transformed intra-or post-operatively transfused blood volume and EBL.
