Bacterial infections are most often to blame for sepsis. But it can also happen because of other infections. It can begin anywhere bacteria, parasites, fungi, or viruses enter your body, even something as small as a hangnail. An infection of the bone, called osteomyelitis, could lead to 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.
Septicemia is an infection that occurs when bacteria enter the bloodstream and spread. It can lead to sepsis, the body's reaction to the infection, which can cause organ damage and even death. Septicemia is more common in people who are hospitalized or have other medical conditions.
What causes sepsis? Bacterial infections are the most common cause of sepsis. Sepsis can also be caused by fungal, parasitic, or viral infections. The source of the infection can be any of a number of places throughout the body.
If left untreated, a bloodstream infection can lead to more serious complications. One of these is sepsis, which is caused by a strong immune response to the infection. Sepsis and septic shock can lead to organ failure and even death.
Treatment includes antibiotics, managing blood flow to organs, and treating the source of the infection. Many people need oxygen and IV (intravenous) fluids to help get blood flow and oxygen to the organs. Depending on the person, help with breathing with a ventilator or kidney dialysis may be needed.
The mortality rate of SIRS ranges from 6% to 7% and in septic shock amounts to over 50%. In particular, abdominal sepsis exhibits the highest mortality rate with 72%. The long-term prognosis is equally poor; only approximately 30% survived the first year after hospital admission.
Many people who survive sepsis recover completely and their lives return to normal. However, as with some other illnesses requiring intensive medical care, some patients have long-term effects.
On average, the recovery period from this condition takes about three to ten days, depending on the appropriate treatment response, including medication.
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.
If the infection has spread or you have a generalized infection, you may develop other signs and symptoms, such as fever, fatigue, pain, etc. Sometimes however, you may have an infection and not know it, and not have any symptoms.
Stage one: Systemic Inflammatory Response Syndrome (SIRS)
Sepsis can be hard to identify, but is typically denoted by a very high or low body temperature, high heart rate, high respiratory rate, high or low white blood cell count and a known or suspected infection.
As severe sepsis usually involves infection of the bloodstream, the heart is one of the first affected organs.
Healthcare professionals should treat sepsis with antibiotics as soon as possible. Antibiotics are critical tools for treating life-threatening infections, like those that can lead to sepsis. However, as antibiotic resistance grows, infections are becoming more difficult to treat.
When treatment or medical intervention is missing, sepsis is a leading cause of death, more significant than breast cancer, lung cancer, or heart attack. Research shows that the condition can kill an affected person in as little as 12 hours.
However, there might be other symptoms related to sepsis based on where the infection is. Abdominal pain is one such symptom.
a wound culture – where a small sample of tissue, skin or fluid is taken from the affected area for testing. respiratory secretion testing – taking a sample of saliva, phlegm or mucus. blood pressure tests. imaging studies – like an X-ray, ultrasound scan or computerised tomography (CT) scan.
The majority of broad-spectrum agents administered for sepsis have activity against Gram-positive organisms such as methicillin-susceptible Staphylococcus aureus, or MSSA, and Streptococcal species. This includes the antibiotics piperacillin/tazobactam, ceftriaxone, cefepime, meropenem, and imipenem/cilastatin.
"When an infection reaches a certain point, this can happen in a matter of hours." Sepsis usually starts out as an infection in just one part of the body, such as a skin wound or a urinary tract infection, Tracey says.
Sepsis may cause abnormal blood clotting that results in small clots or burst blood vessels that damage or destroy tissues. Most people recover from mild sepsis, but the mortality rate for septic shock is about 40%.
When treatment or medical intervention is missing, sepsis is a leading cause of death, more significant than breast cancer, lung cancer, or heart attack. Research shows that the condition can kill an affected person in as little as 12 hours.
