Monitoring of the blood response in blood purification.
A principal objective of monitoring the blood response in procedures such as hemodialysis and cardiopulmonary bypass is to achieve an enhanced understanding of the relationship between blood component alterations and the biomaterials employed. The aim in a study of blood-biomaterial interactions of deriving a correlation between a characteristic of the biomaterial and a representative parameter of the blood response can be influenced in a clinical situation by antithrombotic agents, multimaterial contact, device utilization, blood condition, drug therapy, and the nature of the application. The selection of parameters representative of the blood response may require a compromise between the advantages of multiparameter assessment and the benefit of measuring a single parameter by a consistent methodology. Representative parameters are protein adsorption, platelet reactions, intrinsic coagulation and the contact activation phase, fibrinolysis, leukocyte alterations, and complement activation. Assessment during clinical application can be approached by consideration of blood response patterns.
