[Prevention of thrombosis with low molecular weight heparin and hydroxyethyl starch in general surgery].
In an open, randomized, controlled and prospective study we compared the efficacy of LMWH with unfractionated heparin (UFH) and the effects of both heparin preparations on haemostatic and fibrinolytic parameters. We also stratified subgroups which received HES intra- and postoperatively. The study groups were well matched with regard to baseline characteristics. With LMWH 4 patients (4.1%) displayed a positive fibrinogen uptake test (1 patient with HES). With UFH 5 patients (5%) demonstrated a positive uptake (3 patients with HES). Antifactor Xa levels were significant higher in the LMWH groups; all other fibrinolytic and haemostatic factors, bleeding and local wound complications did not differ. These data suggest that LMWH in equally effective and safe as UFH in general surgery. HES may have and additive effect.
