Overview
Humans have an ability to keep their body temperature stable in relatively wide range of outer temperatures. Temperature loss caused by convection, radiation, evaporation and conduction can be compensated by increased heat production from metabolic muscle activity. This shivering thermogenesis in the newborn is limited, and the heat is created in the brown fat tissue. This method requires an extra energy and oxygen, which may have the negative influence on stability of the neonate.
The goal of thermo management of the newborn is to avoid a temperature stress and to keep the neutral temperature environment. The body temperature measurement and the knowledge of its physiological range in relation to a place of measurement is a tool to keep newborn stable. We provide a range of environmental temperatures for different groups of newborns according to postnatal age and birth weight.
Key words:
body temperature, thermo neutral environment, hypothermia, hyperthermia
