| Abstract: | The impact of the antibiotics carbenicilin and gentamycin on the aggregation and adhesiveness of thrombocytes and on the rotation thrombelastogramme is investigated in healthy newborns. Thrombocyte aggregation was markedly inhibited by carbenicilline; gentamycine had no influence. Thrombocyte adhesiveness was less influenced by both medicaments. The parameters of TEG, viz. reaction time, clotforming time, thrombus elasticity and index were compared before and after rotation and with and without medicaments. Under carbenicilline a prolongation of the clotforming time and a decrease of thrombus elasticity could be shown to exist after rotation. The impact of medicaments on the rotation thrombelastogramme can only be conceived by comparing the values before and after rotation in each case with and without medicament and not simply evaluating it, so that the rotation thrombelastogramms cannot be recommended to be used for assessing the disturbance of thrombocyte function induced by medicaments. |
