Under these conditions, to achieve the maximum benefit from the technique if ANH is used, no homologous blood will be required to maintain the H m if blood loss does not exceed 2940 ml. In such a case, ANH can save a maximum of 1.1 packed red blood cell unit equivalent, and homologous blood transfusion is necessary to maintain H m , even if ANH ...
