Septic Shock

En Español (Spanish Version)

Definition

Septic shock is a condition in which blood pressure falls dangerously and may occur in patients with serious infections. Organ failure may occur because of inadequate blood flow.

Causes

Septic shock is caused by sepsis, which can be triggered by many different kinds of infections, including bacterial, viral, parasitic, or fungal infections.

Risk Factors

The following factors increase your chances of septic shock. If you have any of these risk factors, tell your doctor:

  • Age: newborns and people over age 50
  • Weakened immune system
  • Low white blood cell counts
  • Chronic diseases
  • Previous surgery

Symptoms

If you experience any of these symptoms do not assume it is because of septic shock. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.

  • Confusion
  • Reduced alertness
  • Irregular blood pressure
  • Chills
  • Fever, which may be followed by a drop in body temperature
  • Warm, flushed skin
  • Rapid, pounding heartbeat
  • Rapid breathing
  • Reduced urination
  • Kidney failure
  • Lung failure
  • Heart failure
  • Blood clots

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include the following:

  • Blood tests to measure white blood cells, oxygen levels, platelet count, lactic acid, and metabolic waste
  • Blood tests and cultures to check for infectious organisms
  • Electrocardiogram (ECG)—to check for heart rhythm irregularities

Treatment

Talk with your doctor about the best treatment plan for you. Treatment options include the following:

Supportive Measures for Shock

If you have septic shock, you will be admitted to the intensive care unit where you will be given intravenous fluids, drugs to increase blood flow, and extra oxygen. If your lungs fail, you may be put on a mechanical ventilator to help you breathe. Other therapies or supportive measures may be used.

Medications

Once the cause of the infection is identified, you will be given high doses of one or more antibiotics.

Surgery

Surgery may be performed to remove any dead tissue.

Prevention

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