[A comparison of low dose heparin and oral anticoagulants in the prevention ot thrombo-phlebitis following gynaecological operations (author's transl)].
In a randomized series of patients who underwent gynaecological operations, the prophylactic effect on thrombophlebitis of low dose Heparin was compared to that of oral anti-coagulants. One group (n = 221) received Heparin (Liquemin Roche) subcutaneously in a dosage of 5000 units 2 hours pre-operatively and every 12 hours until the eighth post-operative day. The control group (n = 237) continued to receive the conventional prophylactic medication with Sintrom by mouth from the second post-operative day to complete ambulation keeping the quick test between 20 and 30%. The two groups were more or less identical regarding several risk factors and the following results were obtained: 1. The number of cases of deep thrombophlebitis diagnosed by the I-125-Fibrinogen test was significantly less in the group receiving Heparin than in the group receiving Sintrom. Clinical examination showed the same correlation but only detected 30% of all cases of deep thrombophlebitis. 2. The clinical suspicion of pulmonary embolism was more frequent in the group of patients receiving low dosage Heparin. Most of the symptoms were mild and none of the patients died. 3. During the anti-coagulant treatment the incidence of secondary bleeding was the same in both groups. The prevention of deep thrombophlebitis by low dosage Heparin is a very effective and simple method with few side effects and is superior to the post-operative prophylaxis with oral anti-coagulants.
