Pyrexia

Pyrexia, also known as fever, is a temporary increase in the body's core temperature, usually triggered by an infection or illness. This elevation is a physiological response, where the hypothalamus, the body's thermoregulatory center, resets the temperature set point. While pyrexia can be uncomfortable, it's often beneficial, as it enhances immune function by inhibiting pathogen growth and accelerating the body's healing processes. The severity of pyrexia can vary depending on the cause and individual factors, with higher temperatures often associated with more serious underlying conditions.

Pyrexia meaning with examples

• Following the flu vaccination, the child exhibited mild pyrexia, accompanied by muscle aches, lasting for approximately 24 hours. The pediatrician advised monitoring her temperature and administering acetaminophen if the fever exceeded 101°F. This example illustrates a common and expected immune response following vaccination.
• The patient presented to the emergency room with sudden onset of severe pyrexia, chills, and a cough productive of yellow sputum. Chest X-ray revealed pneumonia. The rapid onset of pyrexia alongside other symptoms necessitated prompt medical attention and initiation of antibiotic therapy.
• Persistent pyrexia in the newborn required comprehensive investigation, ruling out sepsis and congenital infections. The medical team conducted blood tests, urine cultures, and spinal fluid analysis. The underlying cause, potentially a more complex medical condition, was considered as part of the diagnostic process.
• Post-surgical pyrexia can be a normal inflammatory response, indicating the body's attempt to heal; however, if accompanied by wound drainage or increasing pain, it can suggest a wound infection. Frequent temperature checks and monitoring are crucial after any invasive procedure, to catch any complications.
• During the heatwave, prolonged sun exposure led to pyrexia in several individuals, highlighting the risk of heatstroke. The paramedics provided cooling measures and administered intravenous fluids to combat the elevated temperatures. Heatstroke demonstrates a more serious consequence of uncontrolled pyrexia.
