Abstract

Extensive bleeding still remains a major cause of morbidity and mortality in patients undergoing surgery despite the recent achievements in our understanding of hemostasis and availability of modern blood component therapy. In some surgical patients abnormally prolonged operative bleeding due to thrombocytopenia or thrombocytopathia may be corrected by the infusion of platelet concentrates. Evaluation of the requests for platelet transfusion therapy to prevent or to stop excessive thrombocytopenic bleeding should be based on clinical and laboratory data, underlying disease and availability of therapeutic products. In most instances of hemostatic alterations associated with cardiopulmonary bypass operations, the occasional bleeding episodes are related to platelet dysfunction rather than to plasma coagulation abnormalities. While the levels of coagulation factors are usually depleted, principally due to dilution with priming solutions for the oxygenator, only rarely the levels impairing hemostasis are reached. In the early days of open heart surgery, it was thought that freshly drawn whole blood was essential for these procedures but now a days, it seems that stored red blood cells are equally effective. Use of fresh frozen plas...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
