 Normal Haemostatic Cycle

Dr Mehmood

Normal haemostasis is one the most complicated concepts in Haematology. Many useful attempts has been made in many books. I have attempted one as well. It is unique in the sense that:

1. It doesn't follow the typical 'Extrinsic and Intrinsic pathway' style.

2. It encompanses the new concept of 'Prothombinase and X-ases'.

3. It follows the in vivo scheme of events in which Thrombin tries to strengthen its production by activating so-called 'Intrinsic pathway'.

4. It relates the role of pharmacologic agents in haemostasis e.g. Heparin. Warfarin, Streptokinase, and Tranexamic acid.
