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.
Sepsis is a clinical syndrome caused by a deregulated host response to an infection. Any infection can result in sepsis, and multiple organisms, bacterial, fungal and viral, can initiate a septic response. Sepsis is considered the final common pathway by which the vast majority of patients with severe infection die.
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.
What causes sepsis? 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.
High heart rate or weak pulse. Fever, shivering, or feeling very cold. Confusion or disorientation. Shortness of breath.
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.
Sepsis can overwhelm the body. This can cause vital organs to shut down. This usually starts with the kidneys. Blood pressure can drop dangerously low.
IMMEDIATE EVALUATION AND MANAGEMENT — Securing the airway (if indicated) and correcting hypoxemia, and establishing venous access for the early administration of fluids and antibiotics are priorities in the management of patients with sepsis and septic shock [3,4].
Early-onset sepsis remains a common and serious problem for neonates, especially preterm infants. Group B streptococcus (GBS) is the most common etiologic agent, while Escherichia coli is the most common cause of mortality.
Some of the most frequently isolated bacteria in sepsis are Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), Klebsiella spp., Escherichia coli (E. coli), and Pseudomonas aeruginosa (P.
You may need to stay in hospital for several weeks.
The three stages of sepsis are: sepsis, severe sepsis, and septic shock. When your immune system goes into overdrive in response to an infection, sepsis may develop as a result.
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.
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. And sometimes, doctors never discover what the initial infection was.
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.
NICE - the National Institute for Health and Care Excellence - urges hospital staff to treat people with life-threatening sepsis within one hour, in its quality standard. In clinical practice, this is often referred to as the 'golden hour' after diagnosis.
However, there might be other symptoms related to sepsis based on where the infection is. Abdominal pain is one such symptom.
Blood tests may reveal the following signs suggestive of sepsis: Elevated or low white blood cells – Higher than usual levels of leukocytes, known as white blood cells (WBCs), are a sign of a current infection, while too few WBCs indicate that a person is at higher risk of developing one.
Bacterial infections are one of the most common causes of sepsis. Fungal, parasitic and viral infections are also potential sepsis causes.
One of the most common manifestations of sepsis is increased respiratory rate. Tachypnoea (a hallmark of sepsis-induced adult respiratory distress syndrome) can be associated with abnormal arterial blood gases, typically, a primary respiratory alkalosis.
While most patients with sepsis recover fully, those patients who go on to develop severe complications such as septic shock may need additional support and possibly rehabilitation on their road to recovery. Managing sepsis at home, after discharge from the hospital includes addressing several factors.
Once a person is diagnosed with sepsis, she will be treated with antibiotics, IV fluids and support for failing organs, such as dialysis or mechanical ventilation. This usually means a person needs to be hospitalized, often in an ICU.
