[Somatometric and Hemodynamic Measurements after the Total Replacement of Weight Bearing Joint in Preventive Administration of Low-molecular Heparines.].

The authors present outcomes of simple somatometric and impedance measurements of the condition of venous hemodynamics after the total replacement of weight bearing joints with a simultaneous prophylactic application of low molecular heparines (LMH). Measurements in a group of 125 patients (86 females and 39 males) showed increase of circumferences up to symptoms of a swelling on proximal portions of the limb operated on in an early postoperative period; as a rule it reached its peak between 6th and 8th day with a subsequent subsidence in the next period, i. e. until the dismissal of the patient from the hospital. As compared to non-operated extremities the statistical evaluation of circumferences on proximal parts showed a high significance (p = 0,001). Dynamics of these changes reaching the maximum on 6th-8th postoperative day necessitated the adjustment of antithrombotic regimen of administration of low-molecular heparines in the form of therapeutic dosage in 3 of 39 males and 17 of 86 females. There were no clinical symptoms of either venous thrombosis or pulmonary embolization during the hospital treatment. Results of our clinical study document great significance of somatometric measurements of horizontal proportionality of the lower extremity in the post-operative period after total replacement of weight bearing joints for the adjustment of prophylactic administration of LMH and prevention of the incidence of thromboses of deep venous system. Key words: deep venous thrombosis, periodicity of the risk of venous thrombosis, prevention by lowmolecular heparines, somatometric measurements, venous stasis.
