Inability to maintain adequate blood flow through peripheral tissues and arterial blood pressure.
Cause:
- The imbalance between the volume of blood and the volume of the vascular bed caused by:
- reduced blood volume (hypovolemic shock, cold shock)
- by increasing the capacity of the vascular bed (distributive shock, warm shock)
- Hypovolemic shock:
- Hemorrhage
- Burns (hematocrit, toxins, pain)
- Dehydration (AB balance)
- Distribution shock:
- Anaphylaxis (bronchoconstriction)
- Sepsis (fever, toxins)
- Neurogenic vasodilation
The shock phase:
- initial (activation of compensatory mechanisms)
- Progressive (failure of compensatory mechanisms)
Consequences:
- Tissue ischemia and microcirculation
- Consequences of damage to individual organs
Treatment:
- Maintaining the volume of circulating fluid
- Sympathomimetics
- Corticosteroids
