Hemorrhage is defined as a copious discharge of blood from blood vessels. Hemorrhage may be external or enclosed with a tissue, referred to as a hematoma. Hematomas may be minor, such as a bruise or may be severe enough to cause death, depending on the location and size of the hematoma.[1]
Causes
Hemorrhages are typically a complication of an underlying associated condition, but there are some direct causes including:
- Trauma or injury
- Reaction of prescription medications
Associated Conditions
- Anemia
- Hypertension
- Inflammation
- Atherosclerosis
- Stroke
- Thromocytopenia
Types of Hemorrhage
Hemorrhages are typically classified based on size:[1]
- Petechiae refer to small (1 to 2 mm) hemorrhages in skin, mucous membranes or serosal surfaces.
- Purpura refer to larger (greater than 3 mm) hemorrhages.
- Ecchymosis refer to large (greater than 1 to 2 cm) subcutaneous bruises.
- Large internal hemorrhaging is classified based on the specific location, such as hemothorax, hemopericardium, hemoperitoneum or hemoarthrosis.
