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 mother's room in a plastic
bassinet filled with 5 to 51/2 inches of warm water. Mean time was 4.4
hours postbirth. Mean infant temperature was 98.2 degrees F (36.8 deg
rees C) prebath and 98.0 degrees F (36.7 degrees C) postbath. Mean cha
nge was -0.2 degrees F (-0.1 degrees C) and was not significantly diff
erent. This significant absence of heat loss during tub baths suggests
that infants need not be separated from their mothers and kept in nur
series under infrared warmers to prevent heat loss during their first
bath. (C) 1995 by W.B. Saunders Company.
