[The concentration of potassium in the blood and 2,3-diphosphoglyceric acid in the erythrocytes during surgery of the abdominal aorta accompanied by massive blood loss].

It has been demonstrated that transfusions of large amounts of stabilized donor blood and prolonged ischemia due to clamping of the abdominal aorta during surgery were not accompanied by an increase in K+ plasma level thanks to therapy aimed at the correction of hypovolemia and hemodynamic stabilization. A decrease in K+ plasma level directly depended on the volume of the liquid transfused, the degree of hemodilution and to some extent on 2,3-DPG level. There was a drop in 2,3-DPG level intraoperatively, which was due to the use of stored donor blood for blood loss compensation and to mounting metabolic acidosis (lactate acidosis included) and gaseous acidosis.
