Thromboelastographic evaluation of blood coagulation potential in newborns with cephalohematoma
The transition from the intra- to extrauterine life leads to changes in all systems of newborn, including the hemostatic system. Changes in blood coagulation potential can lead both hemorrhagic and thrombotic complications. To evaluate the hemostatic system there is offered many tests, however integrative techniques such as thromboelastography becoming the most important. The aim of the study was to assess blood coagulation in newborns with cephalohematoma according thromboelastography taking into account the platelet component of hemostasis. The study included two groups: children with cephalohematoma and a control group, which included healthy newborns. In children with cephalohematoma according thromboelastography we observed hypercoagulation, that manifests in short reaction time, coagulation time, the time of MA, as well as the angle alpha and parameter G increasing, a high maximum amplitude with high coagulation index and index of thrombodynamic potential. Routine coagulogram characterizes only plasma hemostasis and it is not informative. Children with cephalohematoma have changes in hemostatic platelet component that manifests in decreasing of mean platelet volume and platelet large cell coefficient. The correlation relationship between the value of thromboelastogram maximum amplitude and the number of platelets, as well as plateletcrit was evaluated.
