Non controlled prospective study of the efficacy and tolerance of a low molecular weight heparin

: A prospective trial has been carried out on 50 patients to test the efficacy and tolerance of low molecular weight heparin in surgery involving a high risk of thromboembolic complications. Tedelparin shows a tendency to reduce the frequency of post-operative thromboembolic disease in post-traumatic hip surgery. The effectiveness of the different low molecular weight heparins still remains to be quantified by comparative pharmacological studies. The alternative use of these treatments, whose high tolerance level make suitable for geriatric surgery do not exempt them from the biological monitoring of platelet count as they do not exclude the risk of heparin induced thrombocytopenia syndrome.
