[Use of a 7.5% NaCl/6% Dextran 70 solution in the prevention of hemodynamic disorders during surgery of abdominal aortic aneurysms].

The experience in the application of infusion solutions Ringer lactate (RL) and 6% of Dextran 70 is shown in order to replenish intravascular volume in 19 patients with the abdominal aorta aneurysm after the removal of the aortal clamp and hypertonic-hyper oncotic 7.5% NaCl/6% Dextran 70 solution in 4 to 5 ml/kg dose in 9 patients. The application 7.5% NaCl/6%Dextran 70 at the optimum time, 15-20 min before the removal of aortal clamp, in a dose of 4-5 ml/kg allowed the support of normal hemodynamic function and decreased the need for some solutions or blood, as well as the incidence of intra- and postoperative complications.
