Neonates, particularly very low-birth-weight infants, are susceptible to environmental hypothermia; illness (eg, intracranial hemorrhage, sepsis) increases risk.
Why newborn babies are at risk of hypothermia?
A newborn is more prone to develop hypothermia because of large surface area per unit of body weight. A low birth weight baby has decreased thermal insulation due to less subcutaneous fat and reduced amount of brown fat.
Which infant is at risk for heat loss?
NOTE: The smaller or more premature the newborn is, the greater the risk of heat loss. When heat loss exceeds the newborn’s ability to produce heat, its body temperature drops below the normal range and the newborn becomes hypothermic.
What is the most common way a newborn loses heat?
Newborns lose heat by evaporation after delivery or after a bath. Even a newborn in a wet nappy can lose heat by evaporation. Radiation. This is the loss of heat from a newborn’s skin to distant cold objects, such as a cold window or wall etc.
What is hypothermia in infant?
Definition. Neonatal hypothermia is defined as an abnormal thermal state in which the newborn’s body temperature drops below 36.5 °C (97.7 °F). Progressive reduction in body temperature leads to adverse clinical effects ranging from mild metabolic stress to death.
Which infant would have the greatest risk for evaporative heat loss?
High evaporative heat losses were found in preterm infants on their first days of life, with gradually decreasing values with increasing gestational and postnatal age. It was only during the 1st week of life in infants born at 25-27 weeks of gestation that evaporative heat loss was higher than radiative heat loss.
What to do if a baby has hypothermia?
What to do
- If you suspect a baby has hypothermia, take them to a warm room and dress them in warm clothes. …
- You can also wrap them in a blanket and hold them close to you to help to warm them up.
- Call 999 or 112 for emergency help.
What temperature can a baby get hypothermia?
If your baby’s rectal temperature drops below 95°F (35°C), they’re considered to have hypothermia, per the AAP. Hypothermia is low body temperature. A low body temperature in babies can be dangerous and, though rare, may lead to death.
What are some risk factors for cold stress in a newborn?
The possible risks described have been ecological in nature or limited to hospital-born infants but they do indicate that preterm birth, low birth weight and seasonality (being born during the cold season) are important risk factors for neonatal hypothermia [9,10,12,16-18].
