Trial summary

The avoidance of blood transfusions benefits the patient. Cardiopulmonary bypass (CPB) is routinely used in complex cardiac surgeries. This device requires circulating blood through an oxygenator and pump while the heart is stopped. Read more about this study

About this study

Official title: Comparison of Whole Blood Return and Normal Practice Red Blood Cell Salvage Return Following Cardiopulmonary Bypass

The avoidance of blood transfusions benefits the patient. Cardiopulmonary bypass (CPB) is routinely used in complex cardiac surgeries. This device requires circulating blood through an oxygenator and pump while the heart is stopped. Upon discontinuation of CPB, the volume of blood in the CPB circuit, approximately 1 to 1.5 liters, is currently processed for the red cell components of the blood. Yet, all the other blood components are available in this volume of blood, but are discarded. The Hemobag filters allow for whole blood reinfusion rather than just red cell reinfusion. Thus, the patient's own platelets, for example, are returned to the patient. The product is just being used clinically and we, the investigators at University of Medicine and Dentistry, New Jersey, have been asked to perform a study on our normal practice (red blood cell return as described above) compared to the whole blood return available with the Hemobag™.

Read the detailed description

The HemobagTM is a bag containing a microfilter for separation of autologous whole blood from intravenous solutions to provide a whole blood reinfusion from a cardiopulmonary bypass machine.

Following cardiopulmonary bypass (CPB), blood remaining within the bypass machine circuit is normally processed by a centrifugal separation of fluids from red blood cells (RBCs) and the RBCs are reinfused back into the patient. An FDA approved device, the HemobagTM, provides an alternative by reinfusing whole blood, including RBCs, from the CPB machine circuit. This allows the patient's own whole blood to be returned back to the patient with all components including functioning, non-activated platelets, coagulation factors and plasma. In preliminary human trials, blood measurements were improved in patients whose CPB blood was processed through the HemobagTM.

This study will evaluate 50 patients whose post-CPB blood is processed by normal practice (centrifugal separation of RBCs for reinfusion) or HemobagTM whole blood reinfusion. Outcome measurements will be chest tube drainage for the initial 24 hours following on-pump cardiac surgery, ventilatory requirements, protein levels, transfusion requirements, coagulation profile, A/A gradients, arterial blood gas measures, and CBC blood panels. All of these data are available from the normal clinical care of the patient.

The hypothesis is that the HemobagTM treated patients will have improved physiologic function from the return of whole blood rather than just RBCs following cardiac surgery using CPB.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing HEMOBAG Assessment in people with Cardiopulmonary Bypass and Cardiac Diseases, run by University of Medicine and Dentistry of New Jersey at 1 site in United States.

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 7 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: stopped early, as of the sponsor's last update on 1 May 2007. 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 United States. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Inability to attain sufficient numbers of subjects). Results are not available in the source record.

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?

Hematology value. 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 1 May 2007.
