[Selective ultrafiltration: a new variant of hemoconcentration during surgery with artificial circulation].

: The authors provide an experience with a novel alternative of ultrafiltration hemoconcentration applied to 26 patients in surgery involving extracorporeal circulation. The advantages of the new procedure are maintenance of higher colloid-osmotic pressure, prevention of hyperglycemia, lower body elimination of biologically active compounds and drugs than those observed during the routine procedure of ultrafiltration comprising extracorporeal circulation.
