In Our Own Words

Septicemia, or blood poisoning, is a serious condition, requiring a hospital stay, sometimes in the intensive care unit (ICU). It occurs when disease-causing organisms gain access to the blood, often from an infection elsewhere in the body, such as the lungs, urinary tract or abdomen.


Chills, high fever, fast breathing and rapid heart rate can be among the symptoms. Later, red spots may show up on the skin and mental confusion can set in. Medical attention is crucial, and tests may include blood cultures, blood gas tests, clotting studies and other measures. Treatment includes antibiotics, fluids and medicines by IV to maintain blood pressure, along with oxygen, plasma or other blood products to relieve clotting problems.
