Thermoregulation in Neonates

What is thermoregulation?
Maintaining a constant heart rate
Maintaining a constant core temperature
Maintainging a constant axilla temperature
How does a baby maintain its body temperature?
Uses metabolism (oxygen and glucose) to generate heat, utilises brown fat stores
Sweats and shivers depending on whether it's hot or cold
Puts on a cardigan, adds layers
Why is it important for a neonate to maintain a constant body temperature?
To reduce calorie usage and to grow
To conserve glucose and oxygen
To protect enzyme function
All of the above
 
Brown fat: Surrounds the organs, particularly the kidneys, adrenal glands and in the neck is stored below the clavicle, extending into the axillae. They begin to be laid down from 28weeks
True
False
Neonates can sweat and shiver
True
False
Why is it important to keep a preterm baby warm?
They lack the respiration ability to ensure an oxygen supply and less likely to require appropriate glucose levels required to metabolise to increase core temperature
To ensure optimal homeostatis
So they can maintain their oxygen levels
List the ways heat is lost from a neonate
What happens to a hypothermic neonate?
Increased oxygen demand
Increased metabolism
Increased peripheral resistance
Decreased cardiac output
Decreased enzyme activity
All of the above
Ideal temperature range for a neonate
What happens to a baby under 36 degrees?
They become sleepy
They get tired
Cold stress
They get cold
