Divergent views remain regarding the safety of treating anemia with red blood cell (RBC) transfusion in patients with acute coronary syndrome (ACS). We used a prospective database to study effect of RBC transfusion in patients with acute myocardial infarction (MI; n = 2,358). Cox regression models were used to determine the association between RBC transfusion and 6-month outcomes, incorporating...
BACKGROUND Perioperative red blood cell transfusion is associated with adverse outcomes after cardiac operations. Although restrictive transfusion protocols have been developed, their safety and efficacy are not well demonstrated, and considerable variation in transfusion practice persists. We report our experience with a restrictive transfusion protocol. METHODS We analyzed the outcomes in 4...
BACKGROUND There is little systematically derived evidence-based guidance to inform plasma transfusion decisions. To address this issue, the AABB commissioned the development of clinical practice guidelines to help direct appropriate transfusion of plasma. STUDY DESIGN AND METHODS A systematic review (SR) and meta-analysis of randomized and observational studies was performed to quantify know...
BACKGROUND The ability to predict transfusion requirements may improve perioperative bleeding management as an integral part of a patient blood management program. Therefore, the aim of our study was to evaluate preoperative thromboelastometry as a predictor of transfusion requirements for adult living donor liver transplant recipients. METHODS The correlation between preoperative thromboelas...
BACKGROUND Reservation of blood leads to blood wastage if the blood is not transfused. Therefore, in some centers only blood type and screen are evaluated. In this study, the efficacy of a blood crossmatch-to-transfusion ratio was measured and then compared with the standard levels. METHODS This prospective study was conducted during one year in a university hospital. During this period, 398 ...
BACKGROUND Transfusion services rely on transfusion reaction reporting to provide patient care and protect the blood supply. Unnecessary discontinuation of blood is a major wastage of scarce blood, as well as man, hours and funds. The aim of the present study was to describe the main characteristics of acute transfusion reactions reported in the 4 hospital of Kermanshah University of Medical Sc...
R ecent advances in donor screening, blood testing before transfusion, and modifications made to collected components, with irradiation as an example, make the blood supply safer than ever before. Nonetheless, blood components should only be transfused when risks and benefits have been carefully weighed.1-5 Particular consideration is required when transfusing preterm infants, the most heavily ...
BACKGROUND There is considerable uncertainty regarding the optimal haemoglobin threshold for the use of red blood cell (RBC) transfusions in anaemic patients. Blood is a scarce resource, and in some countries, transfusions are less safe than others because of a lack of testing for viral pathogens. Therefore, reducing the number and volume of transfusions would benefit patients. OBJECTIVES The...
Severe childhood malarial anemia is commonly treated using blood transfusion. Although transfusion may decrease short-term mortality, the risk of human immunodeficiency virus (HIV) transmission is considerable in Africa. We constructed a decision tree to weigh the short-term mortality benefit of transfusion against HIV infection risk. Probability estimates were derived from published studies. T...
