The rheological effects of X-Coating with albumin and hetastarch on blood during cardiopulmonary bypass.

Cardiopulmonary bypass (CPB) exposes blood to artificial surfaces, resulting in mechanical damage to the formed elements of the blood. The purpose of this study was to examine the effect of poly(2-methoxyethylacrylate) coating (PMEA, X-Coating) on coagulation and inflammation under various prime conditions. An in vitro analysis was conducted utilizing fresh whole human blood (2 units) and a CPB circuit (n = 18) consisting of a venous reservoir, oxygenator, and arterial filter.

The effects of aprotinin on platelet function in blood exposed to eptifibatide: an in vitro analysis.

The preoperative use of platelet inhibitors has increased the risk of bleeding during cardiac surgery. Aprotinin has been shown to preserve hemostatic function in patients undergoing CPB. The purpose of this study was to investigate the effect of aprotinin on coagulation in blood exposed to eptifibatide.

Perfusion treatment algorithm: methods of improving the quality of perfusion.

The pathophysiological consequence associated with cardiopulmonary bypass (CPB) has generated a movement away from this technology in the treatment of heart disease. The negative outcomes are multifactorial in origin and may be associated both with the conduct of CPB and the instrumentation of extracorporeal flow. The purpose of this study was twofold.

The effects of preprimed oxygenators on gas transfer efficiency.

Cancellation of on-pump coronary artery bypass grafting after the circuit is primed may result in the discarding of unused circuits. In some off-pump cases, a surgeon may request that the circuit be primed, but complete the surgical procedure without utilizing the circuit. The major concerns about the unused circuit are its sterility and the performance of the oxygenator after it has been primed for a long period of time.

Effects of albumin supplementation during cardioplegia administration: an in vitro analysis.

Increasing, the colloid osmotic pressure (COP) of blood cardioplegia (BCP) may reduce myocardial edema and preserve cardiac function following cardiopulmonary bypass (CPB). The purpose of this study was to quantify the effects of albumin (ALB) supplementation on cardioplegia COP through an in vitro analysis. A self-contained cardioplegia delivery system administered supplemental ALB to four BCP ratios (1:1, 4:1, 8:1, and 20:1).
