Influence of In-line Microfilters on Systemic Inflammation in Adult Critically Ill Patients

May 31, 2015 updated by: Martin W Duenser, MD, DESA, EDIC, University of Salzburg

The Influence of In-line Microfilters on Systemic Inflammation in Adult Critically Ill Patients: A Prospective, Randomized, Controlled Trial

Studies showed that infusion or injection of drugs and fluids results in introduction of microparticles into the bloodstream. These microparticles may cause organ damage and stimulate the immune system thus aggravating the underlying disease. Given that critically ill patients are characteristically suffering from a high disease severity and receive large amounts of fluids and drugs, they may be at particular risk of harm by these microparticles. In-line microfilters have been shown to clear microparticles from intravenous drugs and solutions. The investigators hypothesize that use of in-line microfilters reduce the days with the systemic inflammatory response syndrome in adult critically ill patients.

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.

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.

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.

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.
