About this study

Official title: PP3D - Prospective Combined Validation of an Algorithm for Measurement of Mean Systemic Filling Pressure and Comparison of Invasively Measured Cardiac Output Versus Cardiac Output Calculated by 3D TOE and Carotid Ultrasound.

Prospective combined clinical validation of an algorithmic calculated mean systemic filling pressure (Pms-Nav) with the gold standard for Pms (Pms calculated from venous return curves during inspiratory hold procedures with incremental airway pressures; Pms-Insp). Secondary correlation between invasive cardiac output measurement versus 3D TOE and carotid echo doppler measured cardiac output.

Read the detailed description

Background of the study:

Volume-state in critically ill patients is a difficult parameter to determine, and knowledge about it could make the difference between life or death concerning proper treatment. Determination of volume state starts with adequate 3D transesophageal echocardiography (TOE) in the operation room, including with non-invasive doppler carotid artery measures. TOE is a standardly used method in cardiac surgery. Because echocardiography only gives information about volume status at a certain timepoint, a real-time continuous value reflecting volume-status is needed. "Mean systemic filling pressure (Pms)" appears to be a promising value reflecting volume status. There is a reliable, but cumbersome method available which to date serves as a gold standard to determine Pms (Pms calculated by constructing venous return curves during incremental levels of airway pressure, thereby simulating a decrease in preload --> Pms-Insp). However, this method cannot be used in daily clinical practice because it is laborious and cumbersome. Therefore there is a need for a non-invasive methods measuring Pms, which could now be determined by a computerized algorithm with the Navigator-device (Pms-Nav). It is key to compare this Pms-Nav with its gold standard (Pms-Insp) in order to establish a clinical validation for Pms-Nav.

Objective of the study:

  1. Is there a good correlation between Pms-Nav and Pms-Insp?
  2. Is there a good correlation between invasive continuous cardiac output measurement (by thermodilution and pulse-contour analyse detected by the PiCCO-device) and 3D transoesophageal echocardiography (TOE) and carotid echo doppler?

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical validation of Pms-algorithm

    To determine a correlation between Pms calculated by a computerized algorithm by Navigator(TM) (Pms-Nav) and the gold standard for determining Pms: Pms-Insp. The latter is calculated by performing inspiratory breath holds during incremental airway pressure levels thereby simulating a decrease in preload which, by extrapolating a venous return curve, leads to the true Pms when the curve intersects the x-axis (Pms-Insp).

    Measured: Hours

  1. Correlation invasive continuous cardiac output and 3D-TOE / carotid artery pulsed wave CO measurement.

    Correlation between invasively measured continuous cardiac output (CO) and CO measured by a automated 3D-TOE algorithm and carotid artery PW-measured CO.

Questions about this trial

What is this clinical trial studying?

An observational study of Shock, Cardiogenic and Shock Hypovolemic, run by Catharina Ziekenhuis Eindhoven at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical validation of Pms-algorithm (time frame: Hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04202432, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Dec 2019.
