    Study Notes

    Exudate Types

    • Exudate is fluid and dead phagocytic cells leaking from blood vessels during inflammation, deposited in tissues or on surfaces.
    • Type and amount depend on tissue, inflammation severity/duration, and microorganism presence.
    • Three main types: serous, purulent, and sanguineous (hemorrhagic).

    Serous Exudate

    • Associated with mild inflammation.
    • Clear or straw-colored, thin, watery appearance.
    • Few cells.
    • Example: fluid in a burn blister.

    Purulent Exudate

    • Thicker than serous exudate.
    • Large quantity of cells and necrotic debris.
    • Usually opaque or milky.
    • Also called pus.
    • Formation called suppuration.
    • Pyogenic bacteria cause it (not all microorganisms).
    • Can vary in color (blue, green, yellow) depending on causative organism.

    Sanguineous (Hemorrhagic) Exudate

    • Large number of red blood cells (RBCs).
    • Indicates severe capillary damage allowing RBC escape.
    • Bright color = fresh bleeding.
    • Dark color = older bleeding.
    • Common in open wounds.

    Mixed Exudates

    • Common.
    • Serosanguineous: clear and blood-tinged drainage (e.g., surgical incisions).
    • Purulent-sanguineous: pus and blood (in infected/new wounds).
