This pilot study was designed to verify whether the spraying of coolant improves initial cooling in
extensive burns. The cooling effects of 1l of sprayed water and 5l of poured water (at 22 degrees C) were
tested; 53 healthy participants were cooled for 15 min over 18% of their total body surface, twice.
Thermographic imaging measured the loss of skin temperature and assessed the homogeneity of
cooling. With sprayed coolant the mean decrease of skin temperature was significantly higher (p<0.003)
throughout the entire cooling period and more homogeneous for the first 9min (p<0.003), compared with
poured coolant. Infrared tympanic thermometry estimated core body temperature; neither poured nor
sprayed water caused hypothermia. Even with a fifth of the volume of poured water, sprayed water cooled
more efficiently. Thus, we conclude that spraying of coolant improves initial management.
