Tranexamic Acid in Pediatric Undergoing Proximal Femoral Osteotomies and/or Acetabular Osteotomy

November 14, 2025 updated by: Shimaa Abbas Hassan, Assiut University

Impact of Tranexamic Acid Use on Blood Loss and Transfusion Rates After Hip Reconstruction in Children, A Randomized Controlled Trial

Surgical hip reconstruction reduces the hip joint through soft tissue releases and osteotomies of the femur and/or pelvis. Blood loss and subsequent blood transfusion are normal consequences of hip reconstruction.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

the use of antifibrinolytics (AFs) to limit blood loss peri-operatively has been popularized in certain subspecialties. AFs have been studied extensively in adults undergoing various orthopedic procedures including spine and total joint arthroplasty, and have been proven to reduce blood loss and reduce the risk of blood transfusion. Similarly, AFs are used in pediatric patients undergoing cardiac surgery as well as craniofacial operations. Tranexamic acid (TXA) is a synthetic anti-fibrinolytic agent that works by reversibly blocking plasminogen and thereby promoting hemostasis through the prevention of fibrin degradation. Current literature investigating the safety and effectiveness of TXA in children undergoing orthopedic procedures is limited.

We hypothesize that patients treated with TXA will have reduced blood loss and transfusion requirements compared with those who did not receive TXA.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
400

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
amount of intraoperative blood loss
Time Frame: 24 hours
calculated from the fall in red blood cell volume
24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Rate of blood transfusion
Time Frame: 24 hours
either intraoperative or postoperative blood transfusion
24 hours
Incidence of adverse effects or complications of TXA
Time Frame: 24 hours
e.g. thromboembolic events or perioperative seizures will be managed and recorded
