Modern transfusion practice uses blood that has been separated into specific components (Table 238-1). Coagulation factors, either derived from human plasma or manufactured with recombinant technology, are used treat hemorrhage associated with a deficiency of one or more factors (Table 238-2). Transfusion in the ED typically is done for acute blood loss and/or circulatory shock. As medical care is moved to outpatient settings, emergency physicians may be responsible for transfusion therapy or complications previously relegated to inpatient settings.1
