what is Bacteremia and how to treat it?

Bacteremia is the presence of bacteria in the bloodstream. Usually, bacteremia that results from ordinary events, such as dental procedures, is temporary and causes no symptoms

  • Bacteremia may result from ordinary activities (such as vigorous toothbrushing), dental or medical procedures, or from infections (such as pneumonia or a urinary tract infection).
  • Having an artificial joint or heart valve or having heart valve abnormalities increases the risk that bacteremia will persist or cause problems.
  • Bacteremia usually causes no symptoms, but sometimes bacteria accumulate in certain tissues or organs and cause serious infections.
  • People at high risk of complications from bacteremia are given antibiotics before certain dental and medical procedures.

 

 

Bacteria that are not removed by the immune system may accumulate in various places throughout the body, causing infections there, as in the following:

Tissues that cover the brain (meningitis)

The sac around the heart (pericarditis)

The cells lining the heart valves (endocarditis)

Bones (osteomyelitis)

Joints (infectious arthritis)

 

Causes Of Bacteremia

Bacteremia may occur during

  • Certain ordinary activities
  • Dental or medical procedures
  • Certain bacterial infections
  • Injection of recreational drugs

 

Ordinary activities sometimes cause bacteremia in healthy people. For example, vigorous toothbrushing can cause bacteremia because bacteria living on the gums around the teeth are forced into the bloodstream. Bacteria may also enter the bloodstream from the intestine during digestion. Bacteremia that occurs during ordinary activities rarely leads to infections.

Dental or medical procedures can lead to bacteremia.

During dental procedures (as during tooth cleaning by a dental hygienist), bacteria living on the gums may become dislodged and enter the bloodstream. Bacteremia may also occur when catheters are inserted into the bladder or tubes are inserted into the digestive tract or urinary tract.

Bacteria may be present in the area where the catheter or tube has been inserted (such as the bladder or intestine).

Injecting recreational drugs can cause bacteremia because the needles used are usually contaminated with bacteria, and people may not properly cleanse their skin.

 

Symptoms Of Bacteremia

  • Usually, bacteremia that results from ordinary events, such as dental procedures, is temporary and causes no symptoms.
  • Bacteremia that results from other conditions may cause fever.
  • If people with bacteremia have fever, a rapid heart rate, shaking chills, low blood pressure, gastrointestinal symptoms (such as abdominal pain, nausea, vomiting, and diarrhea), rapid breathing, and/or become confused, they probably have sepsis or septic shock.

Diagnosis Of Bacteremia

  • Culture of a blood sample
  • If bacteremia, sepsis, or septic shock is suspected, doctors usually take a sample of blood so they can try to grow (culture) the bacteria in the laboratory and identify it. If needed, doctors may try to culture bacteria from other samples (such as urine or sputum).

Prevention Of Bacteremia

  • People who are at high risk of complications due to bacteremia (such as those who have an artificial heart valve or joint or certain heart valve abnormalities) are often given antibiotics before procedures that can cause bacteremia:
    • Dental procedures.
    • Surgical treatment of infected wounds.
  • Antibiotics help prevent bacteremia and thus infections and sepsis from developing.

Antibiotics

  • If an infection or sepsis develops, it is treated with antibiotics.
  • Doctors remove sources of bacteria (such as catheters).

 

Treatment Of Bacteremia

  • Antibiotics
  • If an infection or sepsis develops, it is treated with antibiotics.
  • Doctors remove sources of bacteria (such as catheters).
