Treatment of Sick Newborns under Radiant Warmers

  • Stephen Baumgart
Conference paper


Maintaining core body temperature of premature newborn infants exposed to a hostile extrauterine environment in the modern intensive care nursery is essential for the survival and growth of these delicate patients [1–5]. The concept of a thermal neutral environment for best nurturing such babies has become widely accepted [6–11]. The thermal neutral environment may be defined as the set of environmental conditions (particularly environmental temperature) that results in the minimum expenditure of the infant’s precious metabolic energy reserve to maintain body core temperature within a narrow, homeothermic range (37.2–37.5 °C) [9]. Originally, the thermal neutral environment was described within conventional convection warmed incubators in terms of the optimal air temperature and relative humidity, and the optimal incubator mean wall temperature. Thermal neutral conditions varied for infants of different body weights, and gestational and postnatal ages [9, 10].
