The newborn infant must be kept under a neutral thermal environment. This is defined as the external temperature range within which metabolic rate and hence oxygen consumption are at a minimum while the infant maintains a normal body temperature (Figures 8–1 and 8–2 and Table 8–1). The normal skin temperature in the neonate is 36.0°C to 36.5°C (96.8–97.7°F), and the normal core (rectal) temperature is 36.5°C to 37.5°C (97.7–99.5°F). Axillary temperature may be 0.5°C to 1.0°C lower (95.9–98.6°F). A normal body temperature implies only a balance between heat production and heat loss and should not be interpreted as the equivalent of an optimal and minimal metabolic rate and oxygen consumption.
