Blood transfusion = Trasfusione del sangue

There is an ongoing controversy regarding provision of usually matched blood (i.e. matched for ABO-D antigens) or phenotypically matched blood (also matched for Rh and Kell antigens) for multiply transfused thalassaemics, especially in developing countries. A pilot study conducted at our centre revealed an alloimmunisation rate of 3.79% with Rh and Kell alloantibodies accounting for 90% of all antibodies. The present cross-sectional study was conducted to assess the impact of a policy of partial better matching (for Rh cDE and Kell antigens) of blood on alloimmunisation in thalassaemics. ⋯ According to the results of the present study, providing at least partially better matched blood appears to improve the efficacy of transfusion for chronically transfused thalassaemics. Large-scale, comprehensive, multicentre studies need to be carried out to formulate realistic, evidence-based, economically feasible transfusion policies for thalassaemic children based on the red blood cell antigen profile of the population.

Blood transfusion occurring during hospitalisation for heart surgery has been shown to be associated with increased morbidity and mortality and with increased time spent in hospital, use of healthcare services, and costs. The objective of this study was to assess how perioperative blood transfusion among adults 65 years and older who underwent coronary artery bypass graft surgery requiring cardiopulmonary bypass in the United States is associated with immediate and longer term clinical and economic outcomes. ⋯ Blood transfusion during hospitalisation for coronary artery bypass graft requiring cardiopulmonary bypass was significantly associated with increased long-term post-operative morbidity, mortality, and overall healthcare costs. This study contributes to the evidence demonstrating an association between transfusion and adverse clinical and economic outcomes by using a nationally representative longitudinal cost and utilisation database.

Requirements for allogeneic red cell transfusion after total lower limb arthroplasty are still high (20-50%), and post-operative intravenous iron has been shown to reduce transfusion requirements for this surgery. We performed a cost analysis to ascertain whether this alternative is also likely to be cost-effective. ⋯ In patients presenting with or without pre-operative anaemia, post-operative intravenous iron after total lower limb arthroplasty seems to be safe and is associated with reduced transfusion rates, without incremental costs. For anaemic patients, its efficacy could be increased by associating some other blood-saving method.
