Background. Immune Thrombocytopenic Purpura (ITP) in children continues<br />

to be confronted with life threatening bleedings despite its generally<br />

accepted benign evolution. This risk is dependent primarily on<br />

<strong>the</strong> hemostatic efficiency <strong>of</strong> platelets, ra<strong>the</strong>r than <strong>the</strong> platelet count.<br />

Aims. Therefore, looking for a supplementary information about hemostatic<br />

consequence <strong>of</strong> thrombocytopenia and taking into account <strong>the</strong><br />

multiple targets <strong>of</strong> platelets, we aimed a bedside evaluation <strong>of</strong> <strong>the</strong> whole<br />

dynamic process <strong>of</strong> hemostasis by means <strong>of</strong> thrombelastography (TEG)<br />

in ITP patients. Method. Our study included 34 patients: 35,29% with<br />

severe, 26,47% with moderate, and 14,70% with mild ITP. We analyzed<br />

TEG parameters: r (reaction time), k (clot kinetics to reach 20 mm amplitude),<br />

Angle α (clot streng<strong>the</strong>ning), MA (maximum aplitude), G (clot<br />

strength) in correlation with platelet count and some hemostatic explorations:<br />

bleeding time (BT), clot retraction rate (CRR), prothrombin consumption<br />

ratio (PCR) and APTT. Results. In our study, we assessed <strong>the</strong><br />

following hemostatic abnormalities ascribed to thrombocytopenia: PCR<br />
