Abstract
Infrared thermographic calorimetry uses an infrared camera and heat loss equations as a non-invasive method to obtain the energy expenditure of humans. This study focused on preterm infants under radiant warmers, and physiological changes the infants underwent when the radiant heat source was removed. Ten infants with a mean weight of 1.88±1.29 kg (±=SD) showed a mean energy expenditure of 3.08±0.55 kcal kg
−1 h
−1. When the warmer was removed for 2 min and 30 s, heat loss increased to 6.50±1.07 kcal kg
−1 h
−1 and mean body temperature dropped by 1.0±0.3°C. Thirty seconds after the warmer was returned, mean body surface temperature and heat loss returned to original levels.
