It is defined as a systemic nonspecific response of the body to environmental demands or pressures made upon it.

12.Stressor

The stimulus that provokes a stress response is referred to as stressor.

13.Shock

Shock is a pathological process caused by various drastic etiological factors, which is characterized by microcirculation failure resulting from decreased effective circulatory blood volume and inadequate tissue perfusion with the results of cellular metabolism impediment and dysfunction of multiple vital organ.

14.Auto blood transfusion

At the early stage of shock, vessel constriction because of release of a large amount of vasoconstrictors may mobilize the stored blood to participate in the circulation, which is considered as compensation of venous return.

15.Auto fluid transfusion

DIC is a pathological process caused by disturbance of the kinetic balance between coagulation and anticoagulation

systems (including fibrinolytic system). Etiologic factors activate extensive intravascular coagulation and secondary fibrinolysis. The clinical features of DIC are bleeding, shock, organ dysfunction and microangiopathic hemolytic anemia.
