Three Dose Regimen of Tranexamic Acid in Cardiac Surgery

February 1, 2019 updated by: SHI Jia, Chinese Academy of Medical Sciences, Fuwai Hospital

Three Dose Regimen of Tranexamic Acid on Blood Loss and Allogeneic Transfusions in Cardiac Surgery With Cardiopulmonary Bypass

Tranexamic acid is thought to be a promising substitute for aprotinin when the latter has seceded in 2007. Yet the ideal dosage and dosing regimen of tranexamic acid in cardiopulmonary bypass cardiac surgery in Chinese population remains controversial. The current study includes patients receiving valvular replacement and coronary artery bypass surgery. Three dosage regimen of tranexamic acid is delivered and blood loss, transfusions and clinical outcomes are recorded.

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.

Study Type

Enrollment (Anticipated)

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.

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.

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
Rate of exposure to allogeneic erythrocytes transfusions
Time Frame: Perioperatively
Allogeneic RBCs were transfused if the hemoglobin level was less than 6 g/dL during cardiopulmonary bypass, less than 8 g/dL postoperatively, or less than 9 g/dL for elderly people (>70 years).
Perioperatively

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
Length of stay in ICU and hospital postoperatively
Time Frame: Postoperatively
Postoperatively
Volume of allogeneic erythrocytes transfusions
Time Frame: Perioperatively
Allogeneic RBCs were transfused if the hemoglobin level was less than 6 g/dL during cardiopulmonary bypass, less than 8 g/dL postoperatively, or less than 9 g/dL for elderly people (>70 years).
Perioperatively
Rate and volume of fresh frozen plasma transfusion
Time Frame: Perioperatively
