Comparative StudyCardiac marker responses to coronary artery bypass graft surgery with cardiopulmonary bypass and aortic cross-clamping.
To study several markers of myocardial injury in relation to aortic cross-clamping and cardiopulmonary bypass (CPB) after coronary artery bypass graft (CABG) surgery. ⋯ The increase in TnT level is strongly related to aortic cross-clamping.

Randomized Controlled Trial Clinical TrialDiltiazem infusion for renal protection in cardiac surgical patients with preexisting renal dysfunction.
To evaluate if the calcium channel blocker diltiazem protects postoperatively renal function in cardiac surgical patients with preexisting mild-to-moderate renal dysfunction. ⋯ Diltiazem can be safely used in patients who have mild-to-moderate renal dysfunction and undergo cardiac surgery using cardiopulmonary bypass. Within the limits of this study, the data suggest that addition of prophylactic diltiazem may prevent further glomerular damage resulting from cardiopulmonary bypass and may improve glomerular function 3 weeks after cardiac surgery.

Randomized Controlled Trial Clinical TrialPlatelet pheresis is not a useful adjunct to blood-sparing strategies in cardiac surgery.
To examine whether specific platelet pheresis (minimal plasma harvested) would contribute toward reduced blood loss and allogenic blood requirements after cardiac surgery. ⋯ Platelet pheresis activates a proportion of the harvested platelets and impairs the function of the remainder; this may explain its failure to reduce postoperative blood loss and transfusion requirements.

Randomized Controlled Trial Clinical TrialDoes normoxemic cardiopulmonary bypass prevent myocardial reoxygenation injury in cyanotic children?
To evaluate whether the deleterious effect of cardiopulmonary bypass (CPB) can be prevented by controlling PaO(2) in cyanotic children. ⋯ Conventional clinical methods of initiating CPB at a hyperoxemic PO(2) may increase the possibility of myocardial reoxygenation injury in cyanotic children. This deleterious effect of reoxygenation can be modified by initiating CPB at a lower level of oxygen concentration. Subsequent long-term studies are needed to determine the best method of decreasing the oxygen concentration of the CPB circuit.
