Bacteremia

Bacteremia normally causes no symptoms, but bacteria can build in tissues or organs and cause catastrophic diseases. People having an artificial joint or heart valve or heart valve defects increase the risk of bacteremia.

Because the immune system swiftly eliminates bacteria from the bloodstream, bacteremia seldom causes illnesses, especially during everyday activity. Imagine germs are present long enough time and in large quantity concentrations, especially in immuno-compromised persons. In that instance, bacteremia can cause additional diseases and sepsis.

Bacteria that the immune system cannot eradicate can cause infections throughout the body. Meningitis, brain-covering tissues Pericardium, Endocarditis cells line heart valves, Infectious arthritis, and osteomyelitis.

Bacteria accumulate on faulty heart valves in bacteremia. IV catheters, prosthetic joints, and heart valves are especially prone to bacteria growth. These bacteria colonies may remain adhered to the locations and release bacteria into the bloodstream.

Causes of Bacteremia

• Normal activities, dental or medical treatments, bacterial infections, or illicit substance injections can cause bacteremia.
• Because vigorous tooth brushing forces bacteria on the gums around the teeth into the bloodstream, bacteremia can result.
• During digestion, intestinal bacteria can reach the bloodstream. Bacteremia from daily activities seldom causes illnesses.
• Bacteremia can also result from bladder catheters or digestive or urinary tubes.
• Sterile methods may introduce microorganisms into the bloodstream.
• Bacteria can be released from infected wounds, abscesses, and pressure sores during surgery, causing bacteremia.
• Bacteria can enter the bloodstream and cause bacteremia in pneumonia and skin abscesses.
• "Many common childhood bacterial infections can lead to bacteremia."
• The needles used to inject illicit narcotics are often infected with bacteria, and patients may not thoroughly cleanse their skin.

Signs of Bacteremia:

Fever, rapid heart rate, chills, low blood pressure, gastrointestinal problems, rapid breathing, and confusion may indicate sepsis or septic shock.

Diagnostics of Bacteremia

• Lab Test: Bacteria Culture
• Blood sample culture
• When bacteremia, sepsis, or septic shock is suspected, clinicians take a blood sample to grow and identify the bacteria in the lab.
• Doctors may culture microorganisms from urine or sputum if needed.
• Antibiotics are used to treat bacteremia, including infections and sepsis.

To prevent bacteremia

• Doctors remove catheters and germs.
• Antibiotics are typically administered before treatments.
• It can induce bacteremia in people at high risk of complications by having an artificial heart valve or joint or certain heart valve defects.
• Dental procedures
• Surgery for infected wounds

Sepsis/Septic Shock

• Sepsis is a devastating bodywide response to bacteremia or another illness and an essential system failure.
• Septic shock is life-threatening low blood pressure and organ failure from infection.

How sepsis started

A cycle of sepsis disease

1. Certain bacterial infections, sometimes hospital-acquired, cause sepsis.
2. Having a weaker immune system, chronic diseases, an artificial joint or heart valve, or heart valve anomalies increases risk.

symptoms

• The first sign is a high or low body temperature, sometimes accompanied by shaking chills and weakness.
• Severe sepsis causes rapid heartbeat, respiration, confusion, and low blood pressure.
• After seeing symptoms, doctors test blood, urine, or other samples for germs.
• Without delay, antibiotics, oxygen, venous fluids, and blood pressure drugs are given.

Systemic reaction

• The body usually responds to infection locally, such as the bladder for urinary tract infections. 
• In sepsis, the body responds to infection systemically.
• This response usually involves fever or hypothermia and one or more of the following:
• Fast heartbeat, Fast breathing, High or low white blood cell count
• Failure of organs reduces blood supply to body parts.

Sepsis with dangerously low blood pressure is septic shock. Thus, internal organs like the lungs, kidneys, heart, and brain receive too little blood and malfunction. Septic shock is diagnosed when blood pressure remains low after aggressive venous fluid treatment. Life-threatening septic shock.

Causes of Sepsis/Septic Shock

• Sepsis occurs when bacteria create toxins that induce cells to release cytokines that promote inflammation. 
• Cytokines help the immune system fight infection but can harm:
• They dilate blood arteries, lowering blood pressure.
• Blood can clot in microscopic organ blood vessels.

Bacteria infections usually induce sepsis. Only rarely do fungi like Candida cause sepsis. Sepsis-causing infections usually start in the lungs, abdomen, or urinary tract. Most people do not develop sepsis from these infections. Bacteremia happens when bacteria enter the bloodstream. Sepsis may follow. Skin abscesses can cause infection. In toxic shock syndrome, germs that have not yet entered the bloodstream emit toxins that induce sepsis.

Septic shock and sepsis complications

• Low blood pressure and tiny blood clots cause many problems:
• Vital organs like the kidneys, lungs, heart, and brain lose blood.
• The heart works harder to compensate, raising heart rate and blood flow. 
• Bacterial toxins and pumping work weaken the heart. Thus, the heart pumps less blood and important organs receive less.
• Lack of blood causes tissues to produce waste lactic acid into the bloodstream, making it more acidic.
• These effects create a cycle of organ dysfunction:
• Urea nitrogen and other chemical waste products accumulate in the blood because the kidneys produce little or no urine.
• Leaking blood vessel walls lets fluid into tissues and induces edema.
• Leaking blood vessels in the lungs causes fluid to collect, making breathing difficult.
• Microscopic blood clots eat up clotting factor proteins in the bloodlood as they form. Disseminated intravascular coagulation may cause excessive bleeding.

Sepsis/Septic Shock Risk Factors

• People with infection-fighting deficiencies are in danger of sepsis. The following requirements apply:
• A newborn (see Sepsis in Borns)
• Being elderly
• Pregnant
• Chronic diseases like diabetes or cirrhosis
• Having a compromised immune system due to chemotherapy, corticosteroids, or specific illnesses like cancer, HIV infection, and immunological disorders
• Recent antibiotic or corticosteroid treatment
• Being recently hospitalized (particularly in the ICU)
• Septic shock causes low blood pressure despite treatment. Deadly septic shock.

Diagnostics of Sepsis and Septic Shock

• Blood sample culture
• Testing for the infection source (chest X-rays, other imaging procedures, and fluid or tissue cultures)
• When an infection-stricken person gets an extremely high or low temperature, rapid heart rate or breathing rate, or low blood pressure, doctors suspect sepsis.
• Doctors look for bacteremia, another infection that could cause sepsis, and an abnormal amount of white blood cells in a blood sample to confirm the diagnosis.

Sepsis and Septic Shock Treatment

• Antibiotics
• Iv fluids
• Oxygen
• Removal of infection source
• Medications can raise blood pressure.
• Doctors rapidly treat sepsis and septic shock with antibiotics.
• Doctors start antibiotic treatment before test findings since delaying treatment reduces survival. 
• Patients receive hospital care.
• Patients with septic shock or serious illness are admitted to the ICU immediately.

Antibiotics

Doctors choose early medications based on where the infection started and which germs are most probable. UTI germs are distinct from skin infection bacteria. Doctors also consider the most frequent germs in the patient's community and hospital. For unknown bacterium sources, 2 or 3 antibiotics are often given together to boost the odds of killing the germs. After the test results are obtained, doctors can substitute the antibiotic that works best against the infection-causing bacteria.

Iv fluids

Septic shock patients are given massive volumes of intravenous fluid to raise blood pressure. Giving too little fluid is ineffective, but giving too much might cause severe lung congestion.

Oxygen

Masks, nasal prongs, or endotracheal tubes deliver oxygen. Breathing is assisted by a mechanical ventilator.

Removal of infection source

Abscesses are drained. Remove or change catheters, tubes, or other medical equipment that may have caused the infection. Surgery can remove diseased or dead tissue.

Alternative treatments

1. If intravenous fluids don't raise blood pressure, doctors may employ neurotransmitters and hormones to restrict blood arteries. These drugs enhance blood pressure and boost brain, heart, and organ blood flow. Because these drugs narrow organ blood arteries, they may reduce organ blood flow.
2. Patients with septic shock may have high blood sugar. Patients get Into or within vein insulin to reduce blood glucose levels because high blood sugar affects the immune system's response to infection.
3. Man-made drugs that closely resemble cortisol, a hormone that your adrenal glands produce naturally. Those whose blood pressure remains low despite fluids, blood pressure-raising medicines, and infection therapy may be given intravenously.

Conclusion

Most people die from untreated septic shock. Even with treatment, death is likely. It kills more people. However, the risk of death depends on numerous circumstances, including how soon patients are treated, the type of bacteria implicated (especially antibiotic-resistant bacteria), and their overall condition.
