Clinical aspects of blood transfusion in adults

ABSTRACT

The transfusion of blood or blood products may be life-saving or may reduce morbidity but also carries risks. Therefore, it should be prescribed only when it is clearly indicated, after a careful assessment of the benefits and risks for the patient. The pattern of blood usage in developing countries differs from that in developed countries. This reflects the better infrastructure (e.g. availability of safe water and adequate sanitation), public health services and more sophisticated health systems in developed countries, and the prevalence of some hereditary haematological disorders in developing countries. There are also differences in usage among developing countries, with the pattern in a small group similar to that of developed countries. In this paper we discuss the indications and the precedures for transfusion of blood and blood products, and outline the complications of haemotherapy and methods for avoiding or correcting them at the time of transfusion or afterwards (AU)
