Axillary temperature in transitional newborn infants before and after tub bath

Twenty healthy newborn infants (mean 38.4 weeks gestation and 3, 294 g) were studied to compare axillary temperatures before and after a deep-water tub bath. The bath was given in the motherʹs room in a plastic bassinet filled with 5 to 5 1/2 inches of warm water. Mean time was 4.4 hours postbirth. Mean infant temperature was 98.2 °F (36.8 °C) prebath and 98.0°F (36.7 °C) postbath. Mean change was −0.2 °F (−0.1 °C) and was not significantly different. This significant absence of heat loss during tub baths suggests that infants need not be separated from their mothers and kept in nurseries under infrared warmers to prevent heat loss during their first bath
