Trial summary

To overcome the limited accuracy of functional hemodynamic parameters such as stroke volume and pulse pressure variation (SVV and PPV) during spontaneous breathing, a Passive Leg Raising (PLR) manoeuvre has been suggested as a reliable predictor of fluid responsiveness. Read more about this study

About this study

Official title: Assessment of Fluid Responsiveness in Patients After Cardiac Surgery Comparison of Different Functional Hemodynamic Parameters and Tests

To overcome the limited accuracy of functional hemodynamic parameters such as stroke volume and pulse pressure variation (SVV and PPV) during spontaneous breathing, a Passive Leg Raising (PLR) manoeuvre has been suggested as a reliable predictor of fluid responsiveness.

Aim of this study was to evaluate fluid responsiveness using SVV, PPV and PLR during the transition from controlled to spontaneous breathing in cardiac surgery patients

Read the detailed description

In patients after elective off-pump CABG are enrolled hemodynamic measurements are performed in the postoperative period upon arrival in the ICU using a PiCCO2 system (Pulsion Medical Systems, Munich, Germany).

Controlled fluid challenges (500 ml) are done at 3 time-points:

  1. during controlled mechanical ventilation B) during pressure support ventilation with spontaneous breathing and C) after extubation.

Stroke volume (SV), SVV and PPV as well as standard hemodynamic parameters (MAP = mean arterial pressure, HR = heart rate) are assessed.

A PLR is performed before fluid administration at all 3 time points. A positive response is defined as an increase in SV>15 %.

Prediction of fluid responsiveness will be tested by AUC (area under the receiver operating characteristic - ROC - curve).

What is being measured

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

  1. Stroke volume increase > 15%

    Stroke volume increase defines fluid responsiveness

    Measured: 20 min

Questions about this trial

What is this clinical trial studying?

An observational study of Hemodynamics and Patient Monitoring, run by Triemli Hospital at 1 site in Switzerland.

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 2 inclusion and 4 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 15 Nov 2016. 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 Switzerland. 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?

Stroke volume increase > 15% (time frame: 20 min). 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 NCT02571465, which also lists 3 linked publications.

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 15 Nov 2016.
