title: Peroperative infusion of dextran 70 and dextran 40 in the prevention of postoperative deep venous thrombosis as confirmed by the I-125-labelled fibrinogen uptake method.
abstract: The antithrombotic effect of dextran 70 and dextran 40 was studied by a double blind trial in 235 patients with major or medium sized elective procedures. 6% dextran 70 (Macrodex) or 10% dextran 40 (Rhemacrodex) or 5% dextrose in 0.9% saline were given in a double blind manner in 500 ml quantities over 30 minutes starting with the induction of anaesthesia. The diagnosis of deep venous thrombosis was confirmed objectively by the I-125-labelled fibrinogen uptake method. Statistically significant differences in the incidence of deep venous thrombosis between the controls and the dextran groups were not found.
