The Role of Serotonin in Intensive Care Patients (SERO-22)

May 27, 2022 updated by: Morten Rostrup, Oslo University Hospital

The Role of Serotonin in Respiratory and Circulatory Failure in Intensive Care Patients

Sepsis, cardiac arrest and multiple trauma are potentially life-threatening conditions and common reasons for intensive care unit (ICU) admission. The aim of this study is to investigate the role of the signaling substance serotonin in blood in these conditions.

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

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

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
PPP-serotonin
Time Frame: As soon as possible after ICU admission. No more than 3 days after admission.
Serotonin in platelet poor plasma
As soon as possible after ICU admission. No more than 3 days after admission.

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
PPP-serotonin
Time Frame: End of first week at ICU, an average of 5 days after admission.
Serotonin in platelet poor plasma
End of first week at ICU, an average of 5 days after admission.

Serotonin in platelets
End of first week at ICU, an average of 5 days after admission.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Measure Description
Time Frame

Primary Completion (Anticipated)

Primary Completion

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.
