The effect of wound management on the interaction of burn size, heat production, and rectal temperature.
Metabolic and temperature data were collected for 56 patients with burns managed with four wound care protocols. Group I (n = 7) treated with dressings and variable ambient temperature selected for patient subjective comfort; group II (n = 7) managed without dressings and variable ambient temperature for patient comfort; group III (n = 6) no dressings, ambient temperature of 25 degrees C and the output of electromagnetic heaters adjusted for patient comfort; group IV (n = 36) dressings and ambient temperature of 28 degrees C. All groups were cold challenged: groups I and II by sequentially lowering ambient temperature, group III by decreasing the electromagnetic heater output, and group IV by removing dressings with ambient temperature remaining at 28 degrees C. Only groups II and IV demonstrated correlation between percent body surface area burn and heat production. The slope of the regression for group IV neutral was significantly less than that for group IV cold and group II neutral and cold. The relationship between percent body surface area burn and rectal temperature for groups I, II, and III neutral was equal to .03 degrees C increase in rectal temperature per 1% body surface area burn (Y = 37 + 0.03; r = 0.74; df 18; p < 0.01) and was not significantly different when cold. This predicts a 1.5 degrees C increase in rectal temperature for a patient with a 50% body surface area burn who does not have sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)
