Advances in the Prevention and Treatment of Neonatal Hypothermia in Early Birth.

Abstract

Neonates are vulnerable to hypothermia in the early postnatal period due to a low temperature environment, physiological function, and many other factors. In this article, the definition, occurrence status, related factors, hazards, and prevention strategies of neonatal hypothermia are reviewed. The interventions for hypothermia are mainly achieved through three processes, that is, intervention in the delivery room before and after birth, intervention on the way from the delivery room to the neonatal intensive care unit (NICU), and intervention after arrival at the NICU. Rewarming is the main intervention measure after the occurrence of hypothermia and slow rewarming is advocated, based on related studies of early neonatal cold injury syndrome and mild hypothermia treatment of hypoxic-ischemic encephalopathy. Rapid rewarming has been proposed in recent years but remains controversial. There are no detailed guidelines yet for rewarming for early neonatal hypothermia, and there is no precise definition of "rapid rewarming" and "slow rewarming" in terms of the rewarming rate.
