Skin to skin care has been practised in primitive and high technology
cultures for body temperature preservation in neonates. Regional skin
temperature and heat flow was measured in moderately hypothermic term
neonates to quantitate the heat transfer occurring during one hour of
skin to skin care. Nine healthy newborns with a mean rectal temperatur
e of 36.3 degrees C were placed skin to skin on their mothers' chests.
The mean (SD) rectal temperature increased by 0.7 (0.4)degrees C to 3
7.0 degrees C. The heat loss was high (70 Wm(-2)) from the unprotected
skin of the head to the surrounding air. Minute heat losses occurred
from covered areas; and heat was initially gained from areas in contac
t with the mother's skin. The total dry heat loss during skin to skin
care corresponded to heat loss during incubator care at 32-32.5 degree
s C. The reduced heat loss, and to a minor extent, the initial heat fl
ux from the mothers allowed heat to be conserved, leading to rewarming
.
