Study Notes
Definition and Types
- Hemorrhage: excessive bleeding that can occur internally or externally, leading to blood loss and potentially life-threatening complications
- Types of hemorrhage:
- Internal hemorrhage: bleeding within the body, often due to trauma or rupture of internal organs
- External hemorrhage: bleeding from the surface of the body, often due to cuts or lacerations
- Primary hemorrhage: immediate bleeding after injury
- Secondary hemorrhage: delayed bleeding after injury, often due to infection or vessel instability
Causes
- Trauma: physical injury, such as blunt force or penetrating wounds
- Rupture of internal organs: liver, spleen, or other organs
- Vascular disorders: aneurysms, arteriovenous malformations, or blood vessel weaknesses
- Cancer: bleeding from tumors or cancer-related vascular changes
- Surgical complications: bleeding during or after surgery
Signs and Symptoms
- External bleeding: visible bleeding from wounds or orifices
- Internal bleeding: signs of shock, such as:
- Pale or cool skin
- Fast or weak pulse
- Low blood pressure
- Rapid breathing
- Confusion or loss of consciousness
- Other symptoms:
- Pain or tenderness at the site of bleeding
- Swelling or bruising
- Numbness or tingling
Diagnosis
- Physical examination: assessment of bleeding and vital signs
- Imaging studies: CT, MRI, or ultrasound to identify internal bleeding
- Laboratory tests: complete blood count (CBC) to evaluate blood loss and clotting function
Treatment
- Hemorrhage control: direct pressure, tourniquets, or surgical intervention to stop bleeding
- Fluid replacement: intravenous fluids to restore blood volume and prevent shock
- Blood transfusions: administration of packed red blood cells or whole blood to replace lost blood
- Surgical intervention: repair of damaged vessels or organs, or removal of bleeding sources
Complications
- Hypovolemic shock: inadequate blood volume and perfusion of organs
- Organ failure: damage to organs due to prolonged bleeding and hypoperfusion
- Infection: secondary infection of bleeding sites or surgical wounds
- Death: severe bleeding can lead to fatal outcomes if left untreated

Causes
- Trauma, such as blunt force or penetrating wounds, can cause hemorrhage
- Rupture of internal organs, like liver or spleen, can cause hemorrhage
- Vascular disorders, like aneurysms or arteriovenous malformations, can cause hemorrhage
- Cancer and its related vascular changes can cause hemorrhage
- Surgical complications, like bleeding during or after surgery, can cause hemorrhage
Signs and Symptoms
- External bleeding is visible bleeding from wounds or orifices
- Internal bleeding can cause signs of shock, such as pale or cool skin, fast or weak pulse, low blood pressure, rapid breathing, and confusion or loss of consciousness
- Pain or tenderness may occur at the site of bleeding
- Swelling or bruising may occur due to internal bleeding
- Numbness or tingling may occur due to nerve damage
Diagnosis
- Physical examination is used to assess bleeding and vital signs
- Imaging studies, like CT, MRI, or ultrasound, are used to identify internal bleeding

- Surgical intervention involves repairing damaged vessels or organs or removing bleeding sources
Complications
- Hypovolemic shock can occur due to inadequate blood volume and perfusion of organs
- Organ failure can occur due to prolonged bleeding and hypoperfusion
- Infection can occur at bleeding sites or surgical wounds
- Death can occur if severe bleeding is left untreated
