📌Sepsis is a medical emergency that becomes fatal or life-changing for many of the individuals who develop this “blood poisoning.”
Estimates for the number of people hospitalized in the United States for sepsis each year top 1 million and sepsis is in the top 10 of diseases leading to mortality in America.
Sepsis is a specific condition in itself, but it is commonly caused by bacterial infection in the blood, which is called septicemia. This explains why the terms sepsis and septicemia are often used together.
Septicemia leads to sepsis:
Poisons are released by the bacteria involved in septicemia
The immune system mounts a massive inflammatory response to these poisons – this is referred to as sepsis
The current definition of sepsis is based on relatively recent developments in the scientific understanding of the condition. The disease process is also not fully understood , with treatment still proving highly challenging.
Sepsis is defined as “life-threatening organ dysfunction caused by a dysregulated host response to infection.” In lay terms, sepsis is a life-threatening condition that arises when the body’s response to an infection injures its own tissues and organs.
Who is at risk of sepsis ?
Sepsis is possible in anyone with an infection that develops a complication, but the people most at risk of sepsis are the very young and the old, and anyone with these risk factors :
🔆A weakened immune system
🔆Chronic illness, including diabetes, kidney or liver disease, AIDS, and cancer
🔆A severe wound, including severe burns
Vulnerability to sepsis is becoming more widespread. This is thought to be for a number of reasons:
🔆More opportunities for infections to become complicated – more people are having invasive procedures and organ transplants, and more are taking immunosuppressive drugs and chemotherapies
🔆Rising antibiotic resistance – microbes are becoming immune to drugs that would otherwise control infections
*Symptoms of sepsis*
The most important step for patients or people around them suspecting sepsis is that they:
Do not attempt to make a home diagnosis
Instead, get medical help as soon as possible – the symptoms of sepsis from a bad infection are serious
The symptoms can signal other conditions that would also need medical help
The signs and symptoms of sepsis following a bad infection are often subtle and can be mistaken for those of other serious conditions. However, sepsis typically involves the following main features in someone who has had a recent infection, and symptoms can come on quickly.
Get urgent medical help – go to the emergency department whenever sepsis is suspected. It
🔆Fever (high temperature, pyrexia), and there may be chills and shivering
🔆Fast heart rate/pulse ( tachycardia )
🔆Rapid rate of breathing (tachypnea)
🔆Unusual levels of sweating (diaphoresis)
It is particularly important to call for urgent medical help if sepsis has reached a late stage – severe sepsis or septic shock.
Call an ambulance whenever sepsis is suspected and there is
Dizziness or feelings of faintness, Confusion or a drop in alertness, or any other unusual change in mental state, including a feeling of doom or a real fear of death
Diarrhea , nausea, or vomiting
Severe muscle pain and extreme general discomfort
Difficulty breathing – shortness of breath
Low urine output (not needing to urinate for a whole day, for example)
Skin that is cold, clammy, and pale, or discolored or mottled
Skin that is cool and pale at the extremities, signaling poor blood supply (poor perfusion)
Loss of consciousness
Get medical help for anyone whether the skin feels unusually warm or cold; either can happen with sepsis. The elderly and very young are particularly vulnerable to sepsis after an infection and also more vulnerable to the worsening of any sepsis condition.
When calling for medical help, going to the emergency department, or speaking to doctors and nurses, it is important to mention any recent infection, surgical procedure, or if the patient has a compromised immune.
Such a medical history is more likely to mean there has been an infection, this alerts the doctors to the possibility of sepsis if they see the typical features.
*Tests and diagnosis* of sepsis
The first step that doctors take in diagnosing sepsis is to observe the symptoms.
When doctors observe the typical signs and symptoms of sepsis, they will also consider the patient’s medical history and be alerted to possible sepsis if there has been a recent infection, a surgical or catheter procedure, or if the patient is particularly vulnerable to infection – because of compromised immunity, for example.
Physical examination of the patient for signs of sepsis will help confirm the diagnosis.
Blood tests may be carried out, including testing for the infectious agent behind the infection, which can also be tested from other bodily fluids such as sputum. In addition, imaging tests may be done to locate an infection. Tenderness or pain in certain areas physically examined by a doctor may signal the type of infection that has led to the sepsis.
*Treatment of sepsis*
The main treatment for sepsis is antibiotics as most cases are caused by a bacterial infection.
Doctors may have to make a “best guess” at the type of infection and, therefore, the type of antibiotics needed, because speed in treating the infection is of the greatest importance; waiting for laboratory sample tests would hold up a potentially lifesaving intervention.
Antibiotics alone may be sufficient at an early stage of the condition, but treatment needs to be given promptly. For later conditions, hospital treatment may need to be given in an intensive care unit; this can include:
Other means of organ support as necessary
Prevention of sepsis
The CDC have issued three general approaches to reducing the risk of an infection leading to sepsis. The measures are particularly important for the very young, older people, and others who are vulnerable to complications of infection. The
If advised by your doctor, get vaccinated against potential infections, including the flu and pneumonia
Keep any scrapes and wounds clean to prevent infection and follow good hygiene practices such as hand-washing
If there is an infection, stay alert to possible sepsis symptoms – fever, chills, rapid heart rate and rapid breathing, rash, or confusion and disorientation – and get immediate medical attention as soon as they appear.
