[Effects of infusion hemodilution on the state of hemodynamics and oxygen transport in urologic surgery in children].

Analysis of the results of infusion hemodilution and traditional restitution of surgical blood less in 32 children subjected to urological surgery showed that hemodilution is associated with an increase of cardiac output and a reduction of the peripheral vascular resistance. Despite an increase of the volume of blood loss in hemodilution, the parameters of oxygen transport remain the optimal in the course of operation and the immediate postoperative period, an increased level of inorganic phosphates being conducive to maintenance of adequate oxygen metabolism. The authors claim that under conditions of infusion hemodilution donor blood preparations should not be transfused to children with surgical blood loss of up to 20%.
