Brief 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. 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™.
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.
