Abstract
The efficacy of the Siriraj Radiant Warmer Model-2, invented by the investigators for treating environmental hypothermia in newborn infants, was studied. Eleven healthy infants, with a mean birth weight of 2,570+433 g (range 1,910-3,040), mean age at study of 13.2+14.3 hours (range 1-39), and mean pretreatment rectal temperature of 35.7+0.45 0C (range 35.0-36.5) were incubated for two hours in the nursery. The mean rectal temperature rose within 15 minutes of warming and remained within the normal range 45 minutes after treatment. Eight sick infants, admitted to the newborn unit, with a mean body weight of 2,268+499 g (range 1,710-3,000), mean age at study of 10+5.5 days (range 21 hours-19 days), and mean pretreatment rectal temperature of 36.2+0.350C (range 35.7-36.6) were warmed for 48 hours. Within 4 hours of warming, the mean rectal temperature reached 37.00C and stabilized throughout the warming period in all infants but one, whose rectal temperature was 37.60C at the 32nd hour. The Siriraj Radiant Warmer Model-2 can by safely used for rewarming hyporthermic infants and stabilizing body temperature both in short-term warming.
