Entire Body System
- Chills
Symptoms Most patients have fever and chills, often of abrupt onset. However, some patients may be hypothermic (low temperature). Patients may breathe more rapidly and have changes in mental status (how they think, their alertness, etc.). [healthcentral.com]
People with weakened immune systems Infants and children The elderly People with chronic illnesses, such as diabetes, AIDS, cancer, and kidney or liver disease People suffering from a severe burn or physical trauma Common symptoms of sepsis are fever, chills [icdlist.com]
There follows a flu-like illness with fever, chills, malaise, generalized aching (myalgias, arthralgias), headache, nausea, and vomiting. [microbiologybook.org]
Symptoms include chills, lower abdominal pain, bleeding and foul discharge from the vagina, dizziness and collapse. [news-medical.net]
Since this time cannot reliably be predicted, blood culture specimens are appropriately collected during fever and chills, or whenever bacteremia is suspected. Blood cultures are routinely drawn at 60 minute intervals unless otherwise specified. [clinlabnavigator.com]

Various modes of mechanical ventilation and surgical procedures were performed if and when necessary in all patients. [nature.com]
The most common origins of infections that develop into sepsis are UTI, pneumonia, cellulitis, wounds and abscesses, sinusitis, meningitis, and surgical procedures to an infected area or the abdomen (14, 23). [austincc.edu]
Bacteria and yeasts may also be introduced directly into the bloodstream through intravenous drug use or through intravenous catheters or surgical drains. [labtestsonline.org]
Some non-menstrual cases have been associated with rhinoplasty and other surgical procedures in which nasal packing or Teflon ® stints are used to close off spaces. [microbiologybook.org]
- Collapse
Symptoms include chills, lower abdominal pain, bleeding and foul discharge from the vagina, dizziness and collapse. [news-medical.net]
These conditions, together with renal and liver failure, cause cardiac collapse and respiratory failure (ARDS). The signs and symptoms of sepsis vary according to the associated disease processes. However, most symptomology is universal. [austincc.edu]

Fever, chills, tachycardia (rapid heart beat), and tachypnea (rapid respirations) are common acute symptoms of septicemia. When hypotension ( low blood pressure ) and signs of inadequate organ perfusion develop, the condition is termed septic shock. [healthcentral.com]
Vital signs often reveal fever, tachycardia, hypotension, and tachypnea. The patient may appear anxious, delirious, or stuporous. Rapid deterioration is the rule rather than the exception. [microbiologybook.org]
Systemic inflammatory response syndrome is identified when two of the four criteria (fever, tachycardia, tachypnea, and leukocytosis or leukopenia) are met. [aafp.org]
Sepsis Early sepsis is characterized by the systemic inflammatory response syndrome (SIRS) - tachycardia, tachypnea, fever (over 100.4 F or 38oC) or hypothermia (below 96.8 F or 36oC), and leukopenia or leukocytosis. [news-medical.net]

The recommended deep-vein thrombosis prophylaxis for patients with sepsis begins with a combination of low molecular weight heparin (LMWH) and intermittent mechanical compression devices whenever possible. [atrainceu.com]
