    Study Notes

    Haemorrhage

    • Blood leaks from blood vessels due to damage.
    • Can be exacerbated by clotting issues.
    • Occurs in various scenarios: chronically congested tissues, trauma, atherosclerosis.
    • Severity depends on affected blood vessel size.
    • Increased likelihood of bleeding in hemorrhagic diatheses, inherited or acquired disorders affecting blood vessels, platelets, or clotting factors.

    Haemorrhage Forms

    • External bleeding: Blood leaks outside the body.
    • Internal bleeding: Blood accumulates in tissues (hematomas).
    • Hematoma examples:
      • Ecchymoses: Bruises.
      • Hemothorax: Bleeding in the chest.
      • Hemopericardium: Bleeding around the heart.
      • Hemoperitoneum: Bleeding in the abdominal cavity.
      • Hemarthrosis: Bleeding in joints.

    Haemorrhage Complications

    • Jaundice: Possible with large haemorrhages due to hemoglobin breakdown.
    • Hypovolemic shock: Life-threatening condition resulting from significant blood loss.
    • Iron deficiency anemia: Potential consequence of chronic or repeated blood loss.

    Skin Manifestations of Haemorrhage

    • Petechiae: Tiny red or purple spots on the skin, mucous membranes, or serosa surfaces due to small bleedings under the surface.
      • Tiny, clustered, don't change colour when pressed.
      • Can indicate clotting issues, infection, or medication reaction.
    • Purpura: Larger purple or red spots on the skin, similar to petechiae but bigger and more spread out.
      • Occur when small blood vessels burst.
      • Don't fade with time, often indicating an underlying health problem.
    • Ecchymosis: Bruises.
      • Blood leaks from small blood vessels under the skin, causing discoloration.
      • Area turns purple, blue, or black due to hemoglobin conversion to bilirubin and then hemosiderin.
      • Can take days or weeks to heal as the body breaks down trapped blood.
      • Typically caused by injury or trauma, but can also be caused by health conditions or medications affecting blood clotting.

    Clinical Consequences of Haemorrhage

    • Severity depends on blood volume lost, bleeding speed, location, and individual health.
    • Healthy adults can tolerate up to 20% blood volume loss without serious effects.
    • Pre-existing heart or lung issues increase vulnerability to blood loss.
    • Minor external bleeding is usually less serious than internal bleeding in critical areas like the brain.
    • Chronic or repeated blood loss can lead to iron deficiency anemia.
    • Internal bleeding typically doesn't cause iron deficiency due to efficient iron recycling from destroyed red blood cells.
