More than one million patients are hospitalized for sepsis each year. This is more than the number of hospitalizations for heart attack and stroke combined.
People with chronic medical conditions, such as neurological disease, cancer, chronic lung disease and kidney disease, are at particular risk for developing sepsis. And it is fatal. Between one in eight and one in four patients with sepsis will die during hospitalization — as most notably Muhammad Ali did in June In fact sepsis contributes to one-third to one-half of all in-hospital deaths. Despite these grave consequences, fewer than half of Americans know what the word sepsis means.
When you get an infection, your body fights back, releasing chemicals into the bloodstream to kill the harmful bacteria or viruses. When this process works the way it is supposed to, your body takes care of the infection and you get better. This in turn can lead to organ failure and tissue damage.
This is called septic shock. Sepsis can result from any type of infection. Most commonly, it starts as a pneumonia, urinary tract infection or intra-abdominal infection such as appendicitis. 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.
Sometimes the source of the infection must be removed, as with appendicitis or an infected medical device. It can be difficult to distinguish sepsis from other diseases that can make one very sick, and there is no lab test that can confirm sepsis. Many conditions can mimic sepsis, including severe allergic reactions, bleeding, heart attacks, blood clots and medication overdoses.
Sepsis requires particular prompt treatments, so getting the diagnosis right matters. As recently as a decade ago, doctors believed that sepsis patients were out of the woods if they could just survive to hospital discharge. Sepsis survivors also have an increased risk of dying for months to years after the acute infection is cured. Common symptoms include weakness, forgetfulness, anxiety and depression. As a result, blood flow is impaired, depriving organs of nutrients and oxygen and leading to organ damage.
In some cases, the cause can no longer be determined, particularly when a patient is given antibiotics , which can make infectious agents no longer detectable. White blood cells undergoing a cascade of biochemical changes that is part of the immune response. Anyone can develop sepsis. The people at highest risk are infants, children, older adults, and people who have underlying medical problems such as diabetes, AIDS, cancer, or liver disease; have concurrent injuries or surgeries; or are taking certain medications.
Scientists are conducting studies to identify these individual factors. The number of sepsis cases per year in the U. Common symptoms of sepsis are fever, chills, rapid breathing and heart rate, rash, confusion, and disorientation.
Many of these symptoms are also common in other conditions, making sepsis challenging to recognize, especially in its early stages.
Doctors start by checking for the symptoms mentioned above. In addition, they can use a scoring system to determine if the function of a particular organ is declining and note the number of organ systems affected.
Doctors typically treat people with sepsis in hospital intensive care units. They try to stop an infection, protect vital organs, and prevent a drop in blood pressure.
This almost always includes the use of antibiotic medications and fluids. More seriously affected patients might need a breathing tube, kidney dialysis, or surgery to remove an infection. Sepsis patients vary in their immune responses and in their responses to treatment due to individual differences. Scientists are trying to find new therapies and to determine which patients are likely to benefit most from a certain approach. More information about the symptoms, diagnosis, and treatment of sepsis is available from the CDC.
Many patients who survive severe sepsis recover completely, and their lives return to normal. But some people can have permanent organ damage.
For example, in someone who already has impaired kidneys, sepsis can lead to kidney failure that requires lifelong dialysis. If sepsis affects the brain, a person may have problems with thinking, memory, or concentration.
