Studies on Burns:X. Changes in BMR and evaporative water loss in the tretment of severe burns with warm dry dir

Abstract
In a series of 30 severely burned patients treated with warm dry air the calculated mortality was 19.4 cases. Only 5 of the very severely burned patients died. The most important factor responsible for the observed prognostic improvement seems to be the possibility of reducing the heat loss and of diminishing would infection. The basal metabolic rate could be significantly reduced in the burns cases treated with warm dry air as compared with similar cases treated at normal room temperature. During the first 3 weeks of the course of the burn there was a significant correlation between the rate of evaporative loss of water and the extent of burn as well as between changes in the BMR and the extent of burn. Except on the first 2 days, a significant correlation was noted between the changes in the basal metabolic rate and the rate of evaporative loss of water. The patients' metabolic rate increased greatly after surgical cleaning of the wound and removal of skin for grafting. After the graft had been applied, the hypermetabolism decreased quickly in the patients treated with warm dry air.
