[Polish hydroxyethyl starch preparation: a clinical study].

The 6% solution of hydroxyethyl starch (MS = 0.47-0.7, Mw = 120,000-220,000) prepared at the Department of Biochemistry, Institute of Haematology in Warsaw was administered in infusions to a group of surgical patients. It was found that the preparation complied with the conditions and requirements for plasma-replacing agents. In none of the treated patients any side effects were observed. Further investigations will be continued infusing greater volumes of HES to patients with hypovolaemia of different origin.
