Question
What does it mean when someone has "blood poisoning"?
Answer
"Blood poisoning" is not a medical term. It most commonly refers to a bacterial infection in the blood (bacteremia) — and not a poisonous substance in the blood. So "blood poisoning" is really a misnomer.
Bacteria can enter the bloodstream from an intravenous line or an infection on the skin or in deeper body organs and tissues. Those at increased risk of bacteremia include:
- Infants
- People with impaired immune systems
Signs and symptoms of bacteremia may include:
- Sudden, high fever
- Chills
- Rapid heartbeat
- Appearing and feeling seriously ill
A doctor can confirm a diagnosis by:
Treatment of bacteremia, which requires hospitalization, may include:
- Intravenous antibiotics
- Intravenous fluids and medications to improve and maintain blood pressure
- Supplemental oxygen when the lungs are affected
Without prompt treatment, bacteremia can quickly progress to a life-threatening infection (sepsis).
