Before and After Erythrocyte Suspension Transfusion

Hypoperfusion, hypoxia and ischemia occurs in circulation as a result of anemia. All of these situations lead to oxidative stress and endothelial dysfunction in the organism. In this study, the investigators aimed to investigate the oxidant-antioxidant balance and asymmetric dimethylarginine (ADMA) levels in patients that have symptomatic anemia in need of erythrocyte suspension (ES) transfusion. To the best of the investigators knowledge, there have been few studies in the literature on anemia and total oxidant, total antioxidant and ADMA levels. We aimed to observe changes in oxidative - antioxidant ADMA levels before and after ES transfusion.
