Continuous Manual Exchange Transfusion for Patients with Sickle Cell Disease: An Efficient Method to Avoid Iron Overload

Hemostatic imbalances produced by plasma exchange
Abstract:
Ten patients who underwent intensive therapeutic plasma exchange were studied prospectively to determine the nature and extent of changes induced in their coagulation mechanisms. The patients' plasma was replaced with serum albumin and normal saline. Significant changes were noted acutely in the prothrombin time, activated partial thromboplastin time, plasma fibrinogen, and platelet counts. Chronically, significant decreases were found in plasma fibrinogen concentrations and platelet counts. Intensive plasma exchange with fluids devoid of coagulation factors results in defects in the normal hemostatic mechanism.

Blood Transfusion and Agglutination
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
