[Studies on the problem of septic thrombocytopenia and reactive thrombocytosis in obstetrical patients].

During the first 24 hours of septicaemia the platelet count decreases, but in about a week increases again resulting a significant reactive thrombocytose. According to the results of platelet spreading test, the thrombopenia is caused by consumption of young platelets. During the course of increase of platelet count the number of haemostatically most active, newly formed platelets exceeds, and this is why in the periode of reactive thrombocytosis deep-vein thromboses may occure against Heparin or oral anticoagulant treatment.
