Copeptin- Relevance as a Perioperative Marker in Pediatric Cardiac Surgery

September 10, 2019 updated by: Claudia Herbst
This study evaluates the relevance of Copeptin in children with congenital heart disease undergoing cardiac surgery with the need of cardiopulmonary bypass. Three blood samples are taken of each patient. The first and second sample are collected in the operation room before and after the procedure and the third sample on the first postoperative day at the intensive care unit.

Detailed Description

Objective:

Vasopressin is a hormone secreted by the posterior pituitary gland. Its main functions are constriction of blood vessels and reabsorption of water and thereby regulating water balance and hemodynamics of the body. Copeptin is a cleavage product in the synthesis of vasopressin and is released in equimolar amounts. Its stability makes it easier to determine the amount of vasopressin. It is known, that the use of a heart-lung machine in cardiac procedures has effects on the water balance of the body and may affect the vasopressin secretion.

The aim of this prospective clinical trial is, to figure out if copeptin would be suitable for perioperative risk evaluation in neonates and children with congenital heart disease after surgery with the use of a heart-lung machine.

Hypotheses:

The primary outcome endpoint of this study is the change in copeptin concentration perioperatively in patients with congenital heart disease, with the use of heart-lung machine.

Secondary outcome endpoints are correlations between copeptin concentration and complexity of the procedure (based on the aristotle basic score), clinical status and the perfusion times of the heart-lung machine.

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

No older than 6 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The study population consists of 81 patients (neonates, infants, children) with congenital heart disease and the need of cardiac surgery with a heart-lung machine. Parental consent after pre-operative consultation and informing about the study is required.

Description

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
Change of Copeptin concentrations
Time Frame: baseline and up to one day
Change of Copeptin concentrations between the baseline and first postoperative measurement
baseline and up to one day

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
Intubation
Time Frame: up to one day
Duration of intubation time
up to one day
Cardiopulmonary bypass
Time Frame: up to one day
Total time of cardiopulmonary bypass and aortic cross clamp time.
up to one day
ICU stay
Time Frame: up to one day
Length of ICU stay
up to one day
Complexity of procedures
Time Frame: up to one day
The surgical complexity of the procedures undergone by the patients will be shown by using a scoring system developed for this purpose named Aristotle Score
up to one day

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 14, 2017

Primary Completion (Actual)

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
