Thermoregulation in babies immediately after birth.

O R Smales, R Kime

    Archives of Disease in Childhood
    |January 1, 1978
    PubMed
    Summary

    Newborn babies have limited ability to regulate body temperature after birth. Interventions like radiant heaters are effective in preventing heat loss in the delivery room, especially during the first 12 hours of life.

    Area of Science:

    • Neonatal physiology
    • Thermoregulation in newborns

    Background:

    • Postnatal body temperature drop is influenced by infant weight and environment.
    • Newborns exhibit limited thermogenic capacity shortly after birth.

    Purpose of the Study:

    • To investigate the thermogenic capacity of healthy term infants.
    • To identify factors influencing neonatal temperature regulation.
    • To evaluate methods for preventing hypothermia in newborns.

    Main Methods:

    • Assessed oxygen consumption rates at 1.5 hours post-birth.
    • Evaluated the effect of a radiant heater in the delivery room.
    • Observed the impact of washing on infant body temperature.

    Main Results:

    • Oxygen consumption was not significantly correlated with body temperature.
    • Radiant heaters effectively prevented cooling when infants remained with mothers.
    • Washing newborns post-birth led to significant cooling.
    • Healthy term infants demonstrated a limited thermogenic response to cool environments in the first 12 hours.

    Conclusions:

    • Neonatal thermoregulation is limited in the early hours post-birth.
    • Minimizing heat loss is crucial during the first 12 hours of life.
    • Environmental control, such as using radiant heaters, is vital for maintaining infant temperature.
