What are the alternative names for Sepsis?

Septicemia; Sepsis syndrome; Systemic inflammatory response syndrome; SIRS; Septic shock

What are the causes of Sepsis?

The symptoms of sepsis are not caused by the germs themselves. Instead, chemicals the body releases cause the response.

A bacterial infection anywhere in the body may set off the response that leads to sepsis. Common places where an infection might start include the:

  • Bloodstream
  • Bones (common in children)
  • Bowel (usually seen with peritonitis)
  • Kidneys (upper urinary tract infection, pyelonephritis or urosepsis)
  • Lining of the brain (meningitis)
  • Liver or gallbladder
  • Lungs (bacterial pneumonia)
  • Skin (cellulitis)

For people in or recently discharged from the hospital, common sites of infection include intravenous lines, surgical wounds, surgical drains, and sites of skin breakdown, known as bedsores or pressure ulcers.

Sepsis commonly affects infants or older adults.

What are the symptoms of Sepsis?

In sepsis, blood pressure drops, resulting in shock. Major organs and body systems, including the kidneys, liver, lungs, and central nervous system may stop working properly because of poor blood flow.

A change in mental status and very fast breathing may be the earliest signs of sepsis.

In general, symptoms of sepsis can include:

  • Chills
  • Confusion or delirium
  • Fever or low body temperature (hypothermia)
  • Lightheadedness due to low blood pressure
  • Rapid heartbeat
  • Skin rash or mottled skin
  • Warm skin

What are the current treatments for Sepsis?

A person with sepsis will be admitted to a hospital, usually in the intensive care unit (ICU). Antibiotics are usually given through a vein (intravenously).

Other medical treatments include:

  • Oxygen to help with breathing
  • Fluids given through a vein
  • Medicines that increase blood pressure
  • Dialysis if there is kidney failure
  • A breathing machine (mechanical ventilation) if there is lung failure

What is the outlook (prognosis) for Sepsis?

Sepsis is often life threatening, especially in people with a weak immune system or a long-term (chronic) illness.

Damage caused by a decrease in blood flow to vital organs such as the brain, heart, and kidneys may take time to improve. There may be long-term problems with these organs.

How do I prevent Sepsis?

The risk of sepsis can be reduced by getting all recommended vaccines.

In the hospital, careful hand washing can help prevent hospital-acquired infections that lead to sepsis. Prompt removal of urinary catheters and IV lines when they are no longer needed can also help prevent infections that lead to sepsis.

Impact of Prophylactic Antibiotics on Bloodstream Infections After Liberation From Extracorporeal Membrane Oxygenation

Summary: The goal of this prospective interventional study is to evaluate the impact of antibiotic prophylaxis on bloodstream infections after liberation of extracorporeal membrane oxygenation therapy. The main questions aims to answer are: • does application of vancomycine prior to ECMO liberation have an impact of bloodstream infections? Participants will get 1 dose of vancomycine I.V. (15-20 mg per kgKG...
