Septicemia is the presence of bacteria in the blood (bacteremia) and is often associated with severe disease.

Blood poisoning; Bacteremia with sepsis

Septicemia is a serious, life-threatening infection that gets worse very quickly. It can arise from infections throughout the body, including infections in the lungs, abdomen, and urinary tract. It may come before or at the same time as infections of the bone (osteomyelitis), central nervous system (meningitis), or other tissues.

Septicemia can begin with spiking fevers, chills, rapid breathing, and rapid heart rate. The person looks very ill.

The symptoms rapidly progress to shock with decreased body temperature (hypothermia), falling blood pressure, confusion or other changes in mental status, and blood clotting problems that lead to a specific type of red spots on the skin (petechiae and ecchymosis).

There may be decreased or no urine output.

Physical examination may show:

• Low blood pressure
• Low body temperature or fever
• Signs of associated disease (such as meningitis, epiglottitis, pneumonia, or cellulitis)

Tests that can confirm infection include:

• Blood culture
• Urine culture
• CSF culture
• Culture of any suspect skin lesion
• CBC
• Platelet count
• Clotting studies
  • PT
  • PTT
  • Fibrinogen levels
• Blood gases

Septic shock has a high death rate, exceeding 50%, depending on the type of organism involved. The organism involved and how quickly the patient is hospitalized will determine the outcome.

Septicemia can rapidly lead to adult respiratory distress syndrome (ARDS), septic shock, and death.

Septicemia associated with meningococci can lead to shock, adrenal collapse, and Waterhouse-Friderichsen syndrome.

Septicemia is not common but is devastating. Early recognition may prevent progression to shock.

Seek immediate care if:

• A person has a fever, shaking chills, and looks acutely ill
• There are signs of bleeding into the skin
• Any person who has been ill has changes in mental status

Call your health care provider if your child is not current on vaccinations.

Appropriate treatment of localized infections can prevent septicemia. The Haemophilus influenza B (HIB) vaccine has already reduced the number of cases of Haemophilus septicemia and is a routine part of the recommended childhood immunization schedule.

Children who have had their spleen removed or who have diseases that damage the spleen (such as sickle cell anemia) should receive pneumococcal vaccine. Pneumococcal vaccine is not part of the routine childhood immunization schedule.

Persons who are in close contact with someone with septicemia may be prescribed preventative antibiotics.
