• Septic Shock


    Sepsis is a systemic inflammatory response to a severe infection. The inflammatory response triggers a rapid series of events, such as leaking blood vessels and impaired blood flow.
    Severe sepsis is associated with a drop in blood pressure. Low blood pressure reduces the amount of oxygen and nutrients going to the body's organs. This drop causes damage the body's major organs.
    Septic shock occurs when adequate blood pressure can't be restored despite treatment with IV fluids. Septic shock may lead to multiple organ failure and death.


    Septic shock is caused by an infection that overwhelms the body. Sepsis can be triggered by many different kinds of infections including:
    • Bacterial—most common
    • Fungal infections
    • Viral
    • Parasitic

    An infection of the lungs has spread throughout the body, leading to septic shock.

    Risk Factors

    Septic shock is more common in infants and in people over 50 years old. Other factors that may increase your chance of septic shock include:
    • Weakened immune system
    • Absence of your spleen
    • Cancer
    • Low white blood cell counts
    • Chronic diseases
    • Previous surgery


    Septic shock may cause:
    • Fever, which may be followed by a drop in body temperature to below normal
    • Warm, flushed skin
    • Chills
    • Rapid, pounding heartbeat
    • Rapid breathing or trouble breathing
    • Confusion
    • Reduced alertness
    • Irregular blood pressure
    • Reduced urination
    • Severe bleeding (Disseminated intravascular coagulation)
    Complications from septic shock may cause symptoms of:


    Your doctor will ask about your symptoms and medical history. A physical exam will be done.
    Tests may include the following:
    • Blood tests to assess white blood cell counts and inflammatory markers that might indicate how serious the infection is, and oxygen levels and kidney function to assess damage to specific organs.
    • Cultures to check for infectious organisms
    • Electrocardiogram (EKG) to check for heart rhythm irregularities
    • Imaging tests may be used to look for specific sources of infection, such as pneumonia


    Sepsis and septic shock require immediate care. Treatment includes the following:

    Supportive Measures for Shock

    If you have septic shock, you will be admitted to the intensive care unit. There you will be given:
    • IV fluids
    • Medications to increase blood pressure and blood flow to your organs
    • Extra oxygen
    • Corticosteroids may be needed to reduce the inflammatory response, especially if fluids aren't working
    If your lungs fail, you may be put on a mechanical ventilator to help you breathe. Other therapies or supportive measures may be used.


    Once the cause of the infection has been tested for, you will be given high doses of one or more antibiotics or antifungal medications. Once a specific infection is identified, the may be changed.


    Surgery may be performed to remove any dead tissue or drain infections.


    Most cases of septic shock cannot be prevented. Treating bacterial and other infections promptly may help.
