Question: what is bacteremia?
If you have bacteremia there are bacteria in your bloodstream. Often, there are no symptoms and the body fights off the bacteria. However, if the immune system cannot cope, it can lead to other serious conditions, such as sepsis.
Bacteremia is when there are bacteria present in your bloodstream. Another term that you may have heard for bacteremia is 'blood poisoning,' however this isn't a medical term.
In some cases, bacteremia can be asymptomatic, meaning there are no symptoms. In other cases, symptoms may be present and there's a potential risk for serious complications.
Read on to learn more about bacteremia, its symptoms, and how it can be treated.
Question: causes of bacteremia?
A variety of different bacteria can cause bacteremia. Some of these bacteria can go on to establish an infection in the bloodstream.
Examples of such bacteria include:
Staphylococcus aureus, including MRSA
Escherichia coli (E. coli)
Pneumococcal bacteria
Group A Streptococcus
Salmonella species
Pseudomonas aeruginosa
Some common ways in which bacteremia occurs include:
through a dental procedure such as a routine teeth cleaning or through a tooth extraction
from a surgery or procedure
an infection spreading from another part of the body into the bloodstream
via medical devices, particularly in-dwelling catheters and breathing tubes
through severe injuries or burns
Question: What are the usual symptoms of bacteremia?
Some cases of bacteremia are asymptomatic. In these cases, your immune system will often clear the bacteria without you knowing it.
When bacteremia results in a bloodstream infection, you'll likely experience symptoms like:
fever
chills
shaking or shivering
Question: How do doctors usually figure out if someone has bacteremia, diagnosis?
Bacteremia can be diagnosed using a blood culture. To do this, a sample of blood will be taken from a vein in your arm. It will then be sent to a lab to be tested for the presence of bacteria.
Depending on the presumed cause of your infection, your doctor may want to perform additional tests. Some examples include:
sputum culture if you appear to have a respiratory infection or are using a breathing tube
wound culture if you've been injured, burned, or have recently undergone surgery
taking samples from in-dwelling catheters or other devices
Imaging tests such as an X-ray, CT scan, or ultrasound may also be used. These can be used to identify potential sites of infection in the body.
Question: How do doctors usually treat bacteremia?
The treatment for a bloodstream infection requires prompt use of antibiotics. This can help to prevent complications like sepsis from occurring. You'll be hospitalized during treatment.
When bacteria are confirmed in your blood, you'll likely be started on broad-spectrum antibiotics, typically via IV. This is an antibiotic regimen that should be effective against many different types of bacteria.
During this time, the type of bacteria causing your infection can be identified and antibiotic sensitivity testing can be completed.
With these results, your doctor may adjust your antibiotics to be more specific to what's causing your infection.
The length of treatment can depend on the cause and severity of the infection. You may need to be on antibiotics for 1 to 2 weeks. IV fluids and other medications may also be given during treatment to help stabilize your condition.
Question: What are the potential risk factors associated with bacteremia?
If a bloodstream infection is left untreated, you're at risk of developing potentially life-threatening complications such as sepsis and septic shock.
Sepsis occurs due to a strong immune response to an infection. This response can trigger changes in your body such as inflammation. These changes can be harmful and can lead to organ damage.
When septic shock occurs, your blood pressure drops dramatically. Organ failure may also occur.
Symptoms of sepsis and septic shock
If a bloodstream infection progresses to sepsis or septic shock, you may also experience more severe symptoms, such as:
quick breathing
rapid heart rate
skin that's sweaty or feels clammy
a decrease in urination
low blood pressure
changes in mental state, such as feeling confused or disoriented
Risk factors for sepsis and septic shock
Some groups are more at risk for developing sepsis or septic shock from a bloodstream infection. These groups include:
children younger than 1 year old
adults older than 65 years old
people with weakened immune systems
individuals with underlying health conditions like diabetes, kidney disease, or cancer
those that are already very sick or hospitalized
Other potential complications
In addition to sepsis and septic shock, bacteremia can cause other complications to occur. This can happen when the bacteria in your bloodstream travel to other areas of your body.
Additional complications can include:
Meningitis: An inflammation of the tissues surrounding the brain and spinal cord.
Pneumonia: A potentially serious respiratory infection.
Endocarditis: An inflammation of the inner lining of the heart.
Osteomyelitis: A bone infection.
Infectious arthritis: An infection that occurs in a joint.
Cellulitis: An infection of the skin.
Peritonitis: An inflammation of the tissue surrounding your abdomen and organs.
