Hemostasis -1- Learning objectives 1-Defintion & types of Haemostasis 2-What are the Coagulation screening tests 3-What are the response to vascular injury 4- What are the disorders of primary haemostasis 5- Causes of Thrombocytopenia (low platelet count) 6-Causes ,clinical feature and approach to management of ITP 7-Causes ,clinical feature and approach to management of TTP Haemostasis Is the physiological arrest of hemorrhage at sites of vascular leakage. There are mainly 5 systems which interact together to ensure hemostasis, namely : 1. Vascular factors. 2. Platelets. 3. Coagulation system. 4. Natural Coagulation inhibitors. 5. Fibrinolytic system. Coagulation screening tests Normal Situations in which tests may be abnormal range Investigation Thrombocytopenia 150- Platelet count 400×109/L Thrombocytopenia
