Why is hypothermia bad for babies?

The consequences of increased metabolism during hypothermia include hypoglycemia, hypoxia and metabolic acidosis. Behaviorally, cold infants will initially become more agitated, sleep less and lie in a flexed posture to reduce skin exposure to the air.

Why hypothermia is common in newborn?

Neonates are prone to rapid heat loss and consequent hypothermia because of a high surface area to volume ratio, which is even higher in low-birth-weight neonates. There are several mechanisms for heat loss: Radiant heat loss: Bare skin is exposed to an environment containing objects of cooler temperature.

Can a baby be born with hypothermia?

Many babies, even full-term ones, are born with a near hypothermic body temperature. Being born in a cold space can quickly cause your baby’s body temperature to drop.

How many babies die of hypothermia?

A total of 3852 premature neonates (<37 weeks) were admitted to the NICUs from July 2016 to May 2018. Of these infants, 1109 (28.8\%) died and 2991 (79.6\%) had hypothermia.

Why are preterm infants at risk for hypothermia?

The large body surface area in relation to weight and the relative lack of subcutaneous fat make preterm infants at risk for hypothermia (body temperature below 36.5°C), especially in the first few hours after birth [1].

Why can’t babies regulate their temperature?

Babies can’t adjust to temperature changes as well as adults. Babies can lose heat rapidly, nearly 4 times faster than an adult. Premature and low-birth-weight babies don’t have much body fat. Their bodies may not be ready to control their own temperature, even in a warm environment.

How does a baby get hypothermia?

Babies have an underdeveloped mechanism for maintaining their own body temperature and may develop hypothermia easily in a cold environment.

How do you handle hypothermia in premature babies?

Warm the infant in a closed incubator, overhead radiant warmer or warm room. Skin-to-skin care is a very effective method of warming a cold infant. The incubator temperature should be set at 37 °C until the skin temperature returns to normal. Warm water (37 °C) has also been used to correct hypothermia.

Which babies are at higher risk to have hypothermia?

Newborns, infants, and young children are more likely to develop hypothermia because they have a larger surface area compared to body weight so they can lose body heat faster than older children and adults.

Why is cold stress bad for a newborn?

Cold stress is the major risk to naked preterm infants nursed in a dry incubator. Decreased epidermal and dermal thicknesses result in increased heat loss from radiation and conduction. Minimal subcutaneous fat and an immature nervous system also decrease the premature infant’s ability to respond to cooling.

What happens if baby gets too cold?

Babies that are too cold will not exert the energy it takes to cry, and may be uninterested in feeding. Their energy is being consumed by trying to stay warm. A baby that is dangerously chilled will have cold hands and feet and even baby’s chest will be cold under his or her clothes.

What to do if a baby has hypothermia?

What to do

1. If you suspect a baby has hypothermia, take them to a warm room and dress them in warm clothes.
2. You can also wrap them in a blanket and hold them close to you to help to warm them up.
3. Call 999 or 112 for emergency help.

Can hypothermia in newborns be prevented?

Hypothermia in newborns can be prevented if the baby has received proper nutrition for a long time. While it may be difficult, there are many foods that promote the baby’s body temperature. The normal life cycle of a baby involves sucking, breathing, and shedding of its skin and hair.

What is the definition of hypothermia in medical terms?

NOTE: This is the Professional Version. Hypothermia is defined by the World Health Organization as a core temperature < 36.5° C (97.7° F). In premature infants, hypothermia increases morbidity and mortality. Hypothermia may be purely environmental or represent intercurrent illness (eg, sepsis).

Which factors increase the risk of hypothermia during birth?

Slide NH-2, 3. 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.

What is the normal rectal temperature for a hypothermic infant?

Hypothermic infants should be rewarmed, and any underlying condition must be diagnosed and treated. Normal rectal temperature in term and preterm infants is 36.5 to 37.5° C. Although hypothermia is a core temperature < 36.5° C, there may be cold stress at higher temperatures whenever heat loss requires an increase in metabolic heat production.
