Effect of Intravenous Tranexamic Acid on Reduction of Blood Losses in Hip Fracture Patients

April 6, 2022 updated by: Alejandro Lizaur-Utrilla, PhD, MD

Effect of Intravenous Tranexamic Acid on Reduction of Blood Losses in Hip Fracture Patients. A Randomized, Controlled, Double-blind Study

Studies have shown that hip fractures have a significant perioperative blood loss. Postoperative anaemia is associated with a higher morbidity and mortality.

Tranexamic acid is a safe and effective antifibrinolytic widely used to reduce blood loss in other forms of orthopaedic surgery and in traumatized patients. However, evidence on the effectiveness of TXA in lower extremity fracture care is more limited.

Hip fractures represent a common orthopedic injury in a fragile patient population that often necessitates post-operative blood transfusion thereby putting the patient at additional risk of complications.

The goal of this study is to assess if the use of tranexamic acid in patients with hip fractures will result in a reduction in blood losses and blood transfusion rates.

Our hypothesis is that by providing intravenous TXA at the time of surgery will decrease the amount of preoperative and intraoperative bleeding thereby leading to a decreased need for postoperative transfusion.

This a double blinded, placebo controlled, therapeutic trial in which the patients will be randomized to receive TXA or a placebo (saline solution). Treatment will be administered pre-operatively as well as at the time of surgical incision. The primary outcome will be need for blood transfusion. Secondary outcomes will include calculated perioperative blood loss, length of stay, and rate of thromboembolic events, and 90 day mortality.

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

Candidates for the study will be consecutive patients with a diagnosis of hip fractures treated at our center. All patients with hip fracture meeting inclusion criteria will be recruited for enrollment into the study. Informed consent will be obtained from the patient prior to randomization.

At that time, each patient will be randomized into one of two groups by a independent staff using computer generated randomization and allocation concealment. The two patient groups will include:

  1. Study group: 1g of intravenous tranexamic acid at the time of surgical incision.
  2. Control group: placebo injection (saline solution) at the time of surgical incision.

Both patients and the treating surgeons will be blinded with regard to placebo vs. treatment until completion of the study.

Patients will be treated surgically with a long trochanteric femoral nail (TFN) or hemiarthroplasty.

Blood transfusion criteria will remain consistent with hospital standards (Hb<8 g/dL or >9 g/dL if symptomatic anemia). Total number of blood transfusions received will be documented upon patient discharge.

Deep vein thrombosis (DVT) prophylaxis will remain consistent with hospital standards (subcutaneous heparin from admission until 12 hours prior to surgery and beginning 6 hours after surgery). After discharge, .....

Patients will be followed at regular intervals (1mo, 3mo, and at least 6mo) and at each time point the patient will be asked to report any adverse events (DVT, PT, Stroke, myocardial infarction, infection, hospitalization). Diagnostic studies to assess for thromboembolic events (i.e. DVT, pulmonary embolism (PE), and stroke) will be ordered only if the patient develops clinical signs or symptoms that justify their use.

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.
