Outline
Hypovolemic and Distributive Shock
Definition/Etiology:
- Hypovolemic Shock – condition of inadequate organ perfusion caused by acute loss of intravascular volume
- Distributive Shock – pathological redistribution of intravascular volume.
Pathophysiology:
- Hypovolemic – No volume! Blood loss is the most common cause. No volume = no cardiac preload. HR increases to meet demands, but BP is low because we have no volume
- Usual causes – hemorrhage/trauma/internal bleeding
- Distributive shock – you have the volume, but your vessels are on the fritz. Expand to the point that your regular volume is no longer enough to maintain an adequate pressure.
- Usual causes – sepsis, anaphylaxis
Clinical Presentation:
Shock presentation:
- High HR
- Low BP
- Inadequate oxygenation and organ profusion
- Hypovolemic
- Hemorrhage
- Trauma
- Distributive
- Fever
- Low oxygen saturations
- Hives if ampholytic
Collaborative Management:
- Hypovolemic
- Stop the bleed
- Replace the volume
- CBC
- BMP
- Lactic Acid
- Type & Screen
- Blood transfusion
- Distributive
- CBC
- BMP
- Lactic Acid
- Blood cultures
- Fluids
- Epinephrine
- Vasoconstrictors
- Antibiotics
Evaluation | Patient Monitoring | Education:
- Hemodynamic monitoring
- Treatment of the cause
Linchpins: (Key Points)
- Hypovolemic = no volume
- Distributive = volume but no vessels
- Treat the cause
