Randomized Controlled Trial of Pericardial Blood Processing With a Cell-Saving Device on Neurologic Markers in Elderly Patients Undergoing Coronary Artery Bypass Graft Surgery
The present study tested the hypothesis that processing of pericardial shed blood with a cell-saving device during cardiopulmonary bypass would significantly decrease serum levels of protein S100B, and improve brain oxygen saturation and neurologic outcome, all markers of brain injury in elderly patients.

The Use of Corticosteroids for Cardiopulmonary Bypass in Adults
The perioperative application of corticosteroids did not improve mortality rates beyond standard care or other secondary outcomes, such as myocardial infarction, stroke, renal failure, and infection. The observed increased risk of myocardial damage in patients receiving corticosteroids in the SIRS trial is mainly related to the author-defined CK-MB threshold as indicator for early myocardial injury. Interestingly, the use of steroids may have some beneficial effects on secondary outcomes: they significantly decreased the risk of respiratory failure and pneumonia and shortened the length of ICU and hospital stay, but the mechanism involved in pulmonary injury is multifactorial and it is difficult to evaluate this result. Patients receiving steroids did not have a decreased incidence of atrial fibrillation shown by the two large trials unlike some previous small sample size trials have demonstrated.

The Effect of Cardiopulmonary Bypass Prime Volume on the Need for Blood Transfusion After Pediatric Cardiac Surgery
There is increasing awareness that erythrocyte transfusions after pediatric cardiac surgery have deleterious effects. Despite reports of decreased transfusion requirements associated with smaller cardiopulmonary bypass circuits, the relationship between circuit prime volume and need for transfusion has not been systematically examined.
