[Serum lactates in the reconstruction of the aortic bifurcation].

The change in serum lactate level was investigated in 20 patients undergoing reconstruction of the aortic bifurcation. This group of patients was compared with 16 patients undergoing abdominal surgery. There was a remarkable increase of serum lactate in course of the operation in both groups. After the aortic graft serum lactate level was specially elevated (24,96 mg/100 ml +/- 9,71) due to aortic gross-clamping. Simultaneously occurred a decrease in pH and base excess from 7,43 (+/- 0,03) to 7,34 (+/- 0,05) and from -2,2 mmol/1 (+/- 2,5) to -5,7 mmol/l (+/- 1,6). We mentioned the risk of lactic acidosis in vascular surgery caused by fluid therapy with fructose, sorbitol, xylitol and with electrolyte solutions containing lactate.
