Abstract
This review will begin by giving the highlights of the history and explain development of the basic science knowledge of hemoglobin chemistry, function, and physiology. The necessary involvement of red cell metabolism, as it pertains to the maintenance of 2,3-diphosphoglycerate (2,3-DPG) levels, both normally and under the perturbed and experimental conditions of blood storage, will be given as part of the basic science data. The clinical science and transfusion data will comprise the main critical aspects of the paper. Analysis and comment of over 20 studies will be given on the effects of animal and human transfusions with altered 2,3-DPG levels. Decreased survival and organ function have been demonstrated with transfusion of low 2,3-DPG red cells, with or without anemia, in the conditions of exercise, shock, hypotension, ischemia, cardiac surgery, hypoxia, sepsis, and acidosis. By critical analysis of these studies, recommendations on general and specific patient needs for red cell transfusions with normal or high 2,3-DPG levels are given.
