Septicemia is the presence of bacteria in the blood (bacteremia) and is often associated with severe disease.Causes, incidence, and risk factors Return to top
Septicemia is a serious, rapidly progressing, life-threatening infection that can arise from infections throughout the body, including infections in the lungs, abdomen, and urinary tract. It may precede or coincide with infections of the bone (osteomyelitis), central nervous system (meningitis), or other tissues.
Septicemia can rapidly lead to septic shock and death. Septicemia associated with some organisms such as meningococci can lead to shock, adrenal collapse, and disseminated intravascular coagulopathy, a condition called Waterhouse-Friderichsen syndrome.
Septicemia can begin with spiking fevers and chills, rapid breathing and heart rate, the outward appearance of being seriously ill (toxic) and a feeling of impending doom. These symptoms rapidly progress to shock with decreased body temperature (hypothermia), falling blood pressure, confusion or other changes in mental status, and blood-clotting abnormalities evidenced by hemorrhagic lesions in the skin (petechiae and ecchymosis).

Physical examination may show:Treatment Return to top
This disorder must be treated in a hospital, usually with admission to an intensive care unit.Expectations (prognosis) Return to top
Septic shock has a high death rate, exceeding 50%, depending on the type of organism involved. The organism involved and the immediacy of hospitalization will determine the outcome.Complications Return to top
Calling your health care provider Return to top
Septicemia is not common but is devastating and early recognition may prevent progression to shock.Call your health care provider if your child is not current on vaccinations or has not had immunizations for Hemophilus influenza B, commonly referred to as a HIB shot. If your child has a damaged spleen from any disease or has had it removed, schedule an appointment for an immunization against pneumococcal disease.
Prevention Return to top
Appropriate treatment of localized infections can prevent septicemia. HIB vaccine for children has already reduced the number of cases of Hemophilus septicemia (and Hemophilus meningitis, epiglottitis, and periorbital cellulitis) 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.
Close contacts (parents, siblings, friends) of septic children with certain organisms such as pneumococcus, meningococcus, and Hemophilus may require preventive antibiotic therapy. This will be prescribed by the health care provider and the type of antibiotic will be determined by the organism involved.
