Study Notes
Fever in Children
- Fever is a common and normal physiological response to infection.
- Fever is a rise in body temperature above normal.
- In children, any temperature of 38 degrees Celsius or above is considered high.
- For adults, mild fever is 38 to 38.9 degrees Celsius, high fever is 39 to 39.9 degrees Celsius, and very high fever is 40 degrees Celsius or higher.
- Normal human temperature is considered to be 37°C, but can vary by up to 1°C.
- Oral temperature is 37±1ᵒC.
- Rectal temperature is about 0.5ᵒC higher than oral temperature.
- Underarm temperature is about 0.5ᵒC lower than oral temperature.
- A pyrogen is a substance that provokes fever.
- Fever is a by-product of the host response to infection.
- Fever results from an increase in the hypothalamic “set point” in response to endogenous and exogenous pyrogens.
- Hyperthermia is a rare and pathophysiologic response with failure of normal homeostasis (no change in hypothalamic set point) that results in heat production that exceeds capability to dissipate heat.
NICE Guidelines on Fever
- NICE guidelines cover the assessment and early management of fever with no obvious cause in children aged under 5.
- They aim to improve clinical assessment and help healthcare professionals diagnose serious illness among young children who present with fever in primary and secondary care.
Thermoregulation
- The hypothalamus regulates blood temperature.
- It acts as a “thermostat.”
Fever in Children
- Definition: A fever is a rise in body temperature above normal.
- Normal Body Temperature: 37°C (can vary by up to 1°C)
- Fever in Children: Any temperature of 38 degrees Celsius or above is considered high (HSE)
-
Fever in Adults:
- Mild: 38 to 38.9 degrees Celsius
- High: 39 to 39.9 degrees Celsius
- Very High: 40 degrees Celsius or higher
- Fever is a normal physiological response to infection: The hypothalamus, the body's "thermostat", sets a higher temperature in response to endogenous and exogenous pyrogens.
- Fever is beneficial: It fights infection.
- Hyperthermia is different: It is a rare and pathophysiologic response with failure of normal homeostasis.
NICE Guidelines
- The guidelines cover the early management of fever in children under 5 years old.
- They aim to improve clinical assessment and help diagnose serious illness in children presenting with fever.
Thermoregulation
- The hypothalamus regulates blood temperature.
- Normal temperature can vary by up to 1°C.
- A pyrogen is a substance that provokes fever.
Fever in Children
- Fever is a rise in body temperature above normal
- Normal body temperature is considered to be 37°C, oral temperature can vary by 1°C
- For children, any temperature of 38°C or above is considered high
- For adults, a temperature of 38-38.9°C is considered a mild fever, 39-39.9°C is considered a high fever, and 40°C or higher is considered a very high fever
- Fever is a by-product of the host's response to infection
- Fever is a normal physiologic response that results in an increase in the hypothalamic "set point" in response to endogenous and exogenous pyrogens
- Hyperthermia is a rare and pathophysiologic response with failure of normal homeostasis (no change in hypothalamic set point) that results in heat production that exceeds capability to dissipate heat
- Emphasize that fever is not an illness but is a physiologic mechanism that has beneficial effects in fighting infection.
NICE Traffic Light System
- The NICE Traffic Light System is used to assess and manage fever in children under the age of 5
- The system aims to improve clinical assessment and help healthcare professionals diagnose serious illness among young children who present with fever in primary and secondary care
Thermoregulation
- The hypothalamus regulates body temperature
- The hypothalamus is known as the body's "thermostat"
- A pyrogen is a substance that provokes fever
