Reduction of Homologous Blood Requirement During Myocardial Revascularization — Comparison of Four Different Techniques
The risks associated with blood transfusion force us to reduce homologous blood transfusions. Different methods have been described which permit the reduction of blood requirement in open-heart surgery. Because of the inhomogenity of patient groups investigated by others, it is difficult to compare these techniques and to judge their quantitative saving effect. We, therefore, investigated the effect of combined application of different methods on homologous blood requirement in selected homogenous patient groups.
