When germs get into a person's body, they can cause an infection. If you don't stop that infection, it can cause sepsis. Bacterial infections cause most cases of sepsis. Sepsis can also be a result of other infections, including viral infections, such as COVID-19 or influenza, or fungal infections.
Bacterial infections are one of the most common causes of sepsis. Fungal, parasitic and viral infections are also potential sepsis causes. You can get sepsis when an infection triggers a chain reaction throughout your body causing organ dysfunction.
Those that more commonly cause sepsis include infections of: Lungs, such as pneumonia. Kidney, bladder and other parts of the urinary system. Digestive system.
Sepsis can develop quickly from initial infection and progress to septic shock in as little as 12 to 24 hours.1 You may have an infection that's not improving or you could even be sick without realizing it.
This can cause vital organs to shut down. This usually starts with the kidneys. Blood pressure can drop dangerously low. This can cause less oxygen and nutrients to reach your kidneys.
As sepsis worsens or septic shock develops, an early sign, particularly in older people or the very young, may be confusion or decreased alertness. Blood pressure decreases, yet the skin is paradoxically warm. Later, extremities become cool and pale, with peripheral cyanosis and mottling.
The condition can arise suddenly and progress quickly, and it's often hard to recognize. Sepsis was once commonly known as “blood poisoning.” It was almost always deadly. Today, even with early treatment, sepsis kills about 1 in 5 affected people.
Sepsis can be life-threatening and requires prompt and skilled medical care. System): In septic shock, the blood pressure can drop too low to keep the person alive. A person with septic shock can develop chest pain, heart failure, and may appear like he or she is having a heart attack.
Neonatal sepsis may be categorized as early onset (day of life 0-3) or late onset (day of life 4 or later). Of newborns with early-onset sepsis, 85% present within 24 hours (median age of onset 6 hours), 5% present at 24-48 hours, and a smaller percentage present within 48-72 hours.
Many conditions mimic sepsis by meeting criteria for SIRS.
These conditions include: pulmonary embolism (PE), adrenal insufficiency, diabetic ketoacidosis (DKA), pancreatitis, anaphylaxis, bowel obstruction, hypovolemia, colitis, vasculitis, toxin ingestion/overdose/withdrawal, and medication effect.
People with sepsis often develop a hemorrhagic rash—a cluster of tiny blood spots that look like pinpricks in the skin. If untreated, these gradually get bigger and begin to look like fresh bruises. These bruises then join together to form larger areas of purple skin damage and discoloration.
Most sepsis is caused by bacterial infections, but it can also be caused by viral infections, such as COVID-19 or influenza; fungal infections; or noninfectious insults, such as traumatic injury.
Those at the highest risk of developing sepsis include the very young and the very old (infants and seniors), as well as people with chronic or serious illnesses, such as diabetes and cancer, and those who have an impaired immune system. People who are malnourished can also contract infections more easily.
Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and death.
Inflammatory bowel disease can lead to complications, such as a perforated bowel wall, that can cause infection and could lead to sepsis. Sepsis, which was often called blood poisoning, is the body's life-threatening response to infection.
In the worst cases, blood pressure drops, the heart weakens, and the patient spirals toward septic shock. Once this happens, multiple organs—lungs, kidneys, liver—may quickly fail, and the patient can die. Sepsis is a major challenge in hospitals, where it's one of the leading causes of death.
Sepsis needs treatment in hospital straight away because it can get worse quickly. You should get antibiotics within 1 hour of arriving at hospital. If sepsis is not treated early, it can turn into septic shock and cause your organs to fail. This is life threatening.
It's clear that sepsis doesn't occur without an infection in your body, but it is possible that someone develops sepsis without realizing they had an infection in the first place.
Sometimes however, you may have an infection and not know it, and not have any symptoms. Keep this in mind especially if you have recently had surgery or an invasive medical procedure, a break in your skin, or you have been exposed to someone who is ill.
This snapshot summarizes median LOS metrics for sepsis hospitalizations by year during the same surveillance period (Figure). The median LOS for sepsis was 5 days for the period from 2011 through 2017 and declined to 4 days for the years 2018 and 2019. In 2020, the median LOS increased back to 5 days.
Sepsis is known as the 'silent killer' because its symptoms often mimic that of other illnesses such as the flu or gastro. But, if it is identified and treated early, patients can recover.
Septic shock death timeline
Clinically identified cases of septic shock are more likely to pass away within 28 days than undiagnosed cases. Within the first week of diagnosis, sepsis that progresses to severe sepsis or septic shock increases the risk of death.
