Study Notes

Causes of Edema

Increased Hydrostatic Pressure:
- Results from heart failure (HF) and kidney disease; causes fluids to push into interstitial spaces.
- Venous obstruction like deep vein thrombosis (DVT) leads to localized edema.
Decreased Colloidal Osmotic Pressure:
- Loss of plasma proteins (e.g., in extensive burns) and decreased production due to kidney disease, liver disease, and malnutrition results in generalized edema.
Increased Capillary Permeability:
- Inflammation, tissue injury, allergic reactions, and malignancy cause fluids to leak into interstitial space.
Obstruction of Lymphatic Flow:
- Tumors or surgical removal of lymph nodes can lead to lymphedema by blocking lymphatic channels.

Manifestations of Edema

Generalized Edema:
- Seen in conditions like kidney or liver disease, characterized by swelling in face, legs, and feet.
- Associated with acute conditions like pulmonary edema and effusions (pleural and pericardial).
Localized Edema:
- Typically occurs at the site of trauma or specific organ systems (e.g., cerebral, pericardial, and pulmonary edema).
Pitting vs Non-Pitting Edema:
- Pitting Edema: Fluid can be displaced; commonly found in dependent areas like legs.
- Non-Pitting Edema: Fluid accumulation without displacement, often seen in chronic conditions.

Risk Factors and Considerations

Duration of Standing/Bed Rest:
- Prolonged standing or bed rest increases hydrostatic pressure, which can exacerbate venous pooling and edema.
Calf Pump Mechanism:
- Skeletal muscle activity acts as a 'peripheral heart' that helps circulate blood in the lower extremities.

Treatment Strategies

Compression Therapy:
- Use of elastic support stockings and sleeves to reduce edema and improve venous flow velocity.
- Compression massage may enhance lymphatic drainage.
Management of Underlying Conditions:
- Treat conditions contributing to increased hydrostatic pressure, such as heart failure and obstruction.

Third Space Accumulation

Concept of Third Spacing:
- Refers to fluid accumulating in transcellular compartments such as peritoneal, pleural, or pericardial cavities; can be life-threatening depending on the extent.

Hydrodynamics of Fluid Movement

Forces Controlling Fluid Exchange:
- Capillary hydrostatic pressure pushes fluid out into interstitial spaces, while oncotic pressure pulls it back in.
- An imbalance in these pressures leads to edema; conditions like heart failure exacerbate this imbalance.

Emergency Situations

Acute Edema:
- Life-threatening edema can occur rapidly in critical areas such as the brain, larynx, or lungs, requiring immediate medical intervention.
Importance of Monitoring:
- Knowledge of which arm to use for blood pressure in patients who have had lymph node removals is crucial to avoid exacerbating lymphedema.

Summary of Edema Types

Dependent Edema: Common in gravity-dependent areas like legs; can indicate generalized edema if fluid volume increases significantly.
Bilateral vs Unilateral Edema:
- Unilateral edema often associated with surgical history or localized obstruction; bilateral edema more diffuse, indicating systemic issues.
