Hemoglobin Function in Stored Blood
INTRODUCTION The ultimate aim in transfusing blood is the maintenance or restoration of a medium for the transport of oxygen to body tissues. Most often, the efficacy of transfusion therapy is evaluated by survival of the donor erythrocytes in the recipient. However, red cells may have a normal in vivo survival yet be unable to bind and unload oxygen physiologically. In 1956, Valtis and Kennedy...
متن کاملChanges in potassium and sodium concentrations in stored blood
Potassium is the principal intracellular cation with sodium being the principal extracellular cation. Maintenance of the distribution of potassium and sodium between the intracellular and the extracellular compartments relies on several homeostatic mechanisms. This study analysed the effect of blood storage on the concentrations of potassium and sodium in stored blood and also determine any var...
متن کاملThe determination of INR in stored whole blood.
AIMS To examine the reliability of international normalised ratio (INR) determination on samples stored as whole blood for up to two days at room temperature. METHODS The INR of 40 patients receiving oral anticoagulants was determined on fresh blood and on samples stored for 24 and 48 hours, using five locally calibrated prothrombin time systems. These incorporated Manchester reagent, Recombi...
متن کاملStability of carboxyhemoglobin in stored and mailed blood samples.
BACKGROUND Elevated blood carboxyhemoglobin (COHb) levels are used to confirm a clinical diagnosis of exposure to carbon monoxide (CO) and, in some instances, assess severity of poisoning. However, many hospital laboratories cannot measure COHb because they do not have CO-oximeters. In such instances, blood samples are often sent to outside laboratories or with a transported patient for measure...
متن کاملAlterations in cell surface area and deformability of individual human red blood cells in stored blood
The functionality and viability of stored human red blood cells (RBCs) is an important clinical issue in transfusion. To systematically investigate changes in stored whole blood, the hematological properties of individual RBCs were quantified in blood samples stored for various periods with and without a preservation solution called CPDA-1. With 3-D quantitative phase imaging techniques, the op...
