Trial summary

Femoro-femoral cardiopulmonary bypass with retrograde perfusion is needed for totally thoracoscopic cardiac surgery. one of the major complication of retrograde perfusion is organ hypoperfusion. Arterial blood gas analysis can help to detect hypoperfusion or hypoxia during retrograde perfusion. Read more about this study

About this study

Official title: The Difference Between Central and Peripheral Arterial Blood Oxygen Saturation in Patients Undergoing Cardiac Surgery With Different Cardiopulmonary Bypass Strategy

Femoro-femoral cardiopulmonary bypass with retrograde perfusion is needed for totally thoracoscopic cardiac surgery. one of the major complication of retrograde perfusion is organ hypoperfusion.

Arterial blood gas analysis can help to detect hypoperfusion or hypoxia during retrograde perfusion. However,whether the arterial oxygenation status from different parts of the body are the same in the condition of retrograde perfusion have not been studied.

The present study is aimed to determine if there is difference in the arterial oxygenation between peripheral arterial and aortic root during the period of retrograde perfusion.In addition, the impact of artificial ventilation on the difference of arterial oxygenation will also be investigated.

Read the detailed description

All patients included will be assigned into two different groups according to the surgical approach,one group is named "NP" with normal perfusion,and the other is named "RP" with retrograde perfusion.

For all the patients,we will obtain 0.5ml blood from both peripheral arterial and aortic root for blood gas analysis at some specific time points.

We will focus on the differences of arterial oxygenation between peripheral arterial and aortic root at each group.At the same time,we will analyse the impact of artificial ventilation on it.

What is being measured

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

  1. The difference between peripheral arterial oxygenation and aortic root blood oxygenation

    The three time points for blood sample collection are:1.right before clamping the aorta; 2.Three minutes after **** without ventilation;3.5 min after re-initiate mechanical ventilation.

    Measured: patients will be followed up during the cardiopulmonary bypass. Blood samples will be collected at 3 timepoints which is specified in the DESCRIPTION

Questions about this trial

What is this clinical trial studying?

An observational study of Bypass Complications and Disorder of Blood Gas, run by Xijing 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 2 inclusion and 2 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 3 Oct 2012. 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 Min Chen, M.D. (86-13991221157, chenminh@yahoo.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The difference between peripheral arterial oxygenation and aortic root blood oxygenation (time frame: patients will be followed up during the cardiopulmonary bypass. Blood samples will be collected at 3 timepoints which is specified in the DESCRIPTION). 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 3 Oct 2012.
