  • Title: The interrelationships between wound management, thermal stress, energy metabolism, and temperature profiles of patients with burns.

    Journal: J Burn Care Rehabil; 1994; 15(6):499-508. PubMed ID: 7852453.
    Abstract:
    This prospective randomized study was performed to evaluate the metabolic and thermal responsiveness of patients with burns to thermal stress with three protocols of wound care: group I (n = 7) treated with dressings and variable ambient temperature selected for patients subjective comfort; group II (n = 7) treated without dressings and variable ambient temperature for patient comfort; group III (n = 6) treated without dressings and ambient temperature of 25 degrees C, electromagnetic heaters were set to achieve patient subjective comfort; and group IV (n = 6) healthy volunteers. After baseline partitional calorimetry was performed, individual patients were cold-challenged while subjectively comfortable by sequentially lowering either the ambient temperature or the output from the electromagnetic heaters. Heat balance and temperatures were obtained after each perturbation in external energy support. For patients in groups I and II, subjective perception of thermal comfort (warm, neutral, neutral and fed, cool, or cold) was more strongly correlated (p < 0.02) with the changes in the rate of heat production than the actual ambient temperature. For patients treated with electromagnetic heaters, changes in heat production were most strongly correlated with the energy output from the electromagnetic heaters. Even though the environmental conditions required to achieve a particular level of comfort are quite different between treatment groups, the difference in temperature between the patient's surface and ambient is approximately the same for groups I, II, and IV for each subjective state.(ABSTRACT TRUNCATED AT 250 WORDS)
