[Application of anticoagulants in patients after operations for gastro-intestinal bleeding]

Our clinical experience witness the necessity of administration of direct anticoagulants in prophylactic dosage to patients, operated on for gastro-intestinal bleeding. The most effective and secure is preparation of the low molecular weight fractionized heparins group--Fraxparin. The summarized data concerning group of patients, in whom Fraxyparin was applied, witness the absence of unfavourable peak of effect after the preparation injection, gradual action and holding on of the interinjection time plato, the absence of significant additive noncontrollable action of Fraxparin after each subsequent injection made.
