About this study

  1. To evaluate the consistency of cardiac output measured by pulmonary artery catheter and LiDCO in cardiac surgical patients
  2. To evaluate whether different hemodynamic monitoring methods can accurately detect the trend of cardiac output changes
Read the detailed description

Close monitoring of cardiac output (CO), especially in patients before and after intervention(such as volume expansion, diuresis, vasoconstriction, vasodilation therapy), could help to adjust the treatment strategy in cardiac surgical patients. Pulmonary artery catherization (PAC) has been used for hemodynamic monitoring for more than four decades. In spite of its invasiveness, it remains the clinical reference method for the assessment of CO at the bedside. Nowadays, many less invasive alternatives, such as LiDCO Rapid Pulse Contour Analysis System (LiDCO Ltd., Cambridge, United Kingdom), are already available on market. However, consistency between different hemodynamic monitoring results still raise concern. And whether hemodynamic monitoring could accurately detect the changes of these parameters before and after intervention is an important issue in clinical practice. In this study, the investigators are going to collect CO and changes of CO from PAC and LiDCO before and after intervention (passive leg raising and dobutamine stress test) in cardiac surgical patients. Our resulst could provide important reference for cardiac surgical patients how to choose appropriate hemodynamic monitoring tools and how to interpret the results of hemodynamic monitoring.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Passive Leg RaisingDiagnostic test

    Passive leg raising is induced by rasing the legs of patients to 45° from horizontal position.

  • Dobutamine stress testDiagnostic test

    Dobutamine was infused intravenously at the initial dose of 2.5 ug/kg/min. hemodynamic data were recorded from PAC and LiDCO after 5-10 minutes of continuous infusion.

Study groups in NCT04604886
Study groupRoleWhat they receive
Passive Leg RaisingExperimentalPassive leg raising (PLR) test is used to predict fluid responsiveness, which is performed by raising the legs of the patient to 45°. Cardiac output will be collected from both PAC and LiDCO before and after PLR.
Receives: Diagnostic Test: Passive Leg Raising
Dobutamine stress testExperimentalDobutamine is a selective beta 1 receptor agonist. It [<10 ug/(kg.min)] can effectively increase myocardial contractility.
Receives: Diagnostic Test: Dobutamine stress test

What is being measured

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

  1. Baseline Cardiac Output measurement

    Cardiac Output measured at baseline position (horizontal position)

    Measured: within1 minute at baseline position

  2. Cardiac Output measurement after PLR

    Cardiac Output measured after PLR

    Measured: 1 minute after PLR

  3. Cardiac Output measurement after Dobutamine stress test

    Cardiac Output measured after dobutamine stress test

    Measured: 5 minutes after dobutamine stress test

Questions about this trial

What is this clinical trial studying?

A study testing Passive Leg Raising and Dobutamine stress test in people with Cardiac Surgery and Cardiac Output, run by Shanghai Zhongshan Hospital at 1 site in China.

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 3 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: status not confirmed, as of the sponsor's last update on 29 Oct 2020. 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 China. 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?

Results are not available in the source record.

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

Contact Guo-wei Tu, Doctor (86-021-64041990, tu.guowei@zs-hospital.sh.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Baseline Cardiac Output measurement (time frame: within1 minute at baseline position). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Oct 2020.
