Sixty patients selected randomly were given dextran 40 after total hip replacement, 500 ml each day for three days, and then on alternate days until the seventh to 14th day. No effect on morbidity from thromboembolic diseases was observed in them as compared with sixty control patients randomly selected in a similar fashion and not receiving dextran.
