ABSTRACT This study was designed to investigate whether clinical signs of the inflammatory response in pediatric cardiac patients are reduced by heparin-coated cardiopulmonary bypass circuits and how this could be explained by differences in the pathophysiologic mechanisms involved.
In a randomized, prospective study 19 patients underwent cardiopulmonary bypass either with Carmeda BioActive Surface bypass circuits (n = 9) or with identical noncoated circuits (control, n = 10). Clinical parameters were recorded during the first 48 hours after the start of operation. Blood samples for determination of terminal complement complex, soluble form of E-selectin, and beta-thromboglobulin were obtained perioperatively up to 24 hours after operation.
All clinical and inflammatory mediators showed a tendency in favor of the group with heparin-coated circuits. When analyzed on a point-by-point basis there were significant differences in postoperative central body temperature, soluble E-selectin levels, and beta-thromboglobulin levels (all p < 0.05).
These data suggest that the use of heparin-coated cardiopulmonary bypass offers clinical benefit and tends to reduce the release of inflammatory mediators.

    ABSTRACT: Phosphorylcholine coated cardiopulmonary bypass (CPB) circuits for children have been available for some years, but conflicting results regarding the inflammatory response have been reported. Accordingly, we aimed to investigate the effect of phosphorylcholine coating on the inflammatory response. Ten coated and nine uncoated pediatric CPB sets were tested in an in vitro CPB circuit model. The inflammatory response was assessed by serial assays of hemoglobin, hematocrit, leukocyte counts, platelet counts, activation of the complement system, activation of platelets measured as beta-thromboglobulin, activation of neutrophils measured as myeloperoxidase, activation of coagulation measured as prothrombin fragments 1+2, assessment of hemolysis measured as lactate dehydrogenase, and a panel of seven cytokines. Samples were obtained at baseline and after 15, 30, 60 and 120 minutes. There were no significant differences between the phosphorylcholine coated circuits and the uncoated circuits for any of the parameters during the observation period, although a potentially beneficial effect on platelets could not be ruled out. Phosphorylcholine coating of CPB equipment did not exert any beneficial effect on the inflammatory markers monitored.

    ABSTRACT: Heparinization of the blood contact surface in cardiopulmonary bypass circuits has been promoted as an important step in the development of open heart surgery. As it decreases the inflammatory response resulting from the extracorporeal circulation, it may have a positive effect on clinical outcomes. This meta-analysis was carried out to examine if heparin-bonded circuits (HBCs) reduce the need for blood products and improve overall clinical outcome. A systematic literature search was performed to identify randomized controlled trials reporting outcomes of HBCs compared with non-HBCs. Primary outcomes assessed were postoperative blood/blood-product transfusion and blood loss. Secondary outcomes included all-cause mortality, acute postoperative myocardial infarction, stroke, re-sternotomy for postoperative bleeding, wound infection, atrial fibrillation, duration of ventilation, intensive care unit (ICU) and hospital-length of stay (LOS). Random effects meta-analytical techniques were applied to identify differences in outcomes between the two groups. Quality of the included studies and heterogeneity were assessed. From an initial review of 762-published studies, 41-randomized trials fulfilled the inclusion criteria, leaving 3434-patients' data for analysis. HBCs significantly decreased the incidence of blood transfusion required (OR=0.8; 95% CI=0.6:0.9, P=0.004). It also significantly decreased re-sternotomy (OR=0.6; 95% CI=0.4:0.8, P=0.002), duration of ventilation (WMD= -1.3h; 95% CI= -1.9:-0.6, P<0.001), ICU-LOS (WMD= -9.3h; 95% CI=-14.7:-3.9, P<0.001) and hospital-LOS (WMD= -0.5 day; 95% CI= -0.9:-0.1, P=0.02). HBCs had no effect on other adverse events evaluated. Although HBCs showed a positive effect on some of the clinical outcomes, we identified only marginal differences for other outcomes. Further evaluation of the cost-effectiveness of this technology is required.
