Trial summary

The study is about comparing blood samples obtained from the superior vena cava and the pulmonary artery. The investigators will compare the values of PCO2 and PO2 from these two sites, in order to see if exists a PCO2 gap and a PO2 gap, different from zero. Read more about this study

About this study

Official title: Evaluation of PCO2 and PO2 Values in the Pulmonary Artery and in the Superior Vena Cava: Relationship With Cardiac Output, Hematocrit and Post Operative Organ Dysfunction

The study is about comparing blood samples obtained from the superior vena cava and the pulmonary artery. The investigators will compare the values of PCO2 and PO2 from these two sites, in order to see if exists a PCO2 gap and a PO2 gap, different from zero. Moreover the investigators want to find out if these gaps are related with changes in the cardiac output, the hematocrit or if they can predict post operative dysfunctions.

Blood samples will be taken at six different times as scheduled by the protocol. Along with the two venous blood samples, an arterial blood sample will be taken too, from a radial of femoral artery catheter.

What participants receive

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

  • blood samplesOther

    blood samples will be obtained from the superior vena cava (via centra venous catheter), from the pulmonary artery (via Swan Ganz catheter), and from a radial or femoral artery catheter

What is being measured

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

  1. PCO2 gap changes

    See if exists a PCO2 pa-svc gap different from zero in patients undergoing cardiac surgery

    Measured: two days

  2. PO2 gap changes

    See if exists a PCO2 pa-svc gap different from zero in patients undergoing cardiac surgery

    Measured: two days

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Diseases, run by Catholic University of the Sacred Heart at 2 sites in Italy.

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 3 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 31 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Italy. 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?

PCO2 gap changes (time frame: two days). The study lists 2 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 31 Jul 2019.
