Red blood cell storage lesion.
The past two decades have witnessed increased scrutiny regarding efficacy and risk of the once unquestioned therapy of red blood cell (RBC) transfusion. Simultaneously, a variety of changes have been identified within the RBC and storage media during RBC preservation that are correlated with reduced tissue oxygenation and transfusion-associated adverse effects. These alterations are collectivel...
متن کاملVascular effects of the red blood cell storage lesion.
Transfusion of RBCs is often clinically necessary--and life-saving--for anemic patients. RBCs can be stored for up to 42 days between the time of donation and the time of transfusion. For many years, investigators have studied the biochemical changes that occur in RBCs stored before transfusion (the RBC "storage lesion"). More recently, clinical studies have suggested that RBC units stored for ...
متن کاملRed blood cells storage lesion: the effect of blood donation time on biochemical parameters
Abstract Background and Objectives There is a circadian rhythm and diurnal variation in the redox capacity in blood plasma and there is a decrease in antioxidant capacity (TAC) during the RBCs storage in blood banking. So it is possible that donated blood, based on donation time, has a different antioxidant capacity and as a result a different biochemical response during storage. This study at...
متن کاملEvaluation of Blood Storage Lesions in Leuko-depleted Red Blood Cell Units
Background: Red blood cells (RBCs) undergo biochemical and morphologic alterations during storage that are known as the storage lesions causing decreased RBC quality and are correlated with transfusion reactions in certain groups especially in infants and critically ill patients. Microvesicles (MVs) as one of storage lesions may be derived from various cell types and have key roles in several...
متن کاملClinical effects of red blood cell storage.
BACKGROUND Well-characterized biochemical, structural, and physiological changes occur when red blood cells (RBCs) are stored for a period of time and are collectively called the storage lesion. METHODS Key study results are summarized and contrasted and new data from recently completed randomized controlled trials will be discussed. RESULTS It is unclear whether in vitro changes to RBCs th...
