An Evaluation of Clotting Factor Activity Before and After Total Hip Arthroplasty (CloFaTHA)

April 29, 2020 updated by: Dariusz Tomaszewski, Military Institute of Medicine, Poland

A Comprehensive Evaluation of Thrombotic/Fibrinolytic Activation Before and After Total Hip Arthroplasty

The objective of the study was to analyze both the concentration and the activity of the clotting factors, D-dimer levels, as well as fibrinogen concentration in patients who underwent primary total hip arthroplasty due to idiopathic arthrosis.

Blood loss is often related to perioperative period and may result in decrease of concentration of coagulation factors, which in turn may lead to increased bleeding. We analyzed data of thirty patients scheduled for primary hip arthroplasty: the activity of clotting factors II, VIII, X, as well as fibrinogen concentration in the following time points: (i) before surgery, (ii) six hours after the procedure, and (iii) two, (iv) four, and (v) six days after the operation. All laboratory tests were performed using automatic analyzer. At the same time intervals, an immunoenzymatic assay was used to determine D-dimer levels.

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.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

There were 12 men and 18 women in the study group. Mean age: 67 years. Mean body mass index: 26. Mean ASA score: II.

Description

Inclusion Criteria:

  • patients qualified for primary hip arthroplasty for idiopathic osteoarthritis

Exclusion Criteria:

  • hip osteoarthritis because of non-idiopathic etiology
  • history of venous thromboembolism or arterial embolism
  • anticoagulation treatment,
  • coagulopathy

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.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
