[Significance of postoperative substitution of plasma proteins].

In the course of a pilot study 30 patients, who had to undergo extensive urological-abdominal surgery, were randomized and divided into two groups. One group received 500 ml of the stored serum Biseko on the day of operation as well as on the first postoperative day, the other group was given a placebo. The two groups were compared with regard to their complications rates (wound healing disturbance, respiratory disturbance on account of septicemia). It turned out, that there occurred clearly less complications in the group treated with Biseko than in the control group.
