![]() Inhalation burns occur as the result of breathing superheated gases, hot liquid or steam, etc. Inhalation burns are the most serious immediate life threat that can present both with or without an accompanying thermal burn. Caused by electrical current passing from electric outlet Caused by exposure to reactive chemicals such as acids Caused by hot solids or items such as a hot cooking item Thermal burns involve the skin and may be seen as any of the following: Classification by cause would be classified as either thermal or inhalation. ![]() The three most common characteristics used are cause, depth and extent of the burn. There are multiple characteristics used in the classification of burns. It is imperative for EMS clinicians to understand how heat energy is transferred, how burns are classified and immediate treatment of those burns. As EMS clinicians, we are in a unique position to be able to provide proactive education to patients as we enter their homes. Many of these burn injuries could often be avoided with basic household safety and maintenance. These situations are often stressful for emergency medicine clinicians, not only because of the injury caused by the burn, but because burns are more likely to happen to children and older adults, two age groups that already elicit larger amounts of stress from emergency clinicians. Therefore, heart rate may be considered a useful variable to be used for the evaluation of the energy requirements of severely burned patients.It is imperative for EMS clinicians to understand how heat energy is transferred, how burns are classified and immediate treatment of those burns. In burn patients, variability in heart rate is associated with a significant part of postburn hypermetabolism variability. 0001), and each of these variables also had a significant partial correlation with fasting resting metabolic rates (r2 = 0.45, p <. In a multiple regression analysis, predicted resting metabolic rate, heart rate, and total burn surface area together explained 77% of all of the variance observed in the 48 fasting resting metabolic rates that were measured in the study (r2 = 0.77, p <. ![]() 02) there was no correlation with body temperature. Only in the second week did postburn hypermetabolism correlate with total burn surface area (r = 0.52, p =. In each week postburn hypermetabolism correlated with heart rate (r = 0.65, p =. Postburn hypermetabolism was +36% +/- 19%, +55% +/- 27%, and +36% +/- 35% in the first, second, and third week, respectively. ![]() Twenty-three patients were studied weekly for 3 weeks after an overnight fast. ![]() We tested whether heart rate, which relates to the energy expenditure during physical activity, is also associated with postburn hypermetabolism (calculated as percentage increase of resting metabolic rate above the predicted normal fasting resting metabolic rate). Although frequently done, estimating the energy requirements of individual burn patients without measuring their resting metabolic rate is a less than satisfactory method of evaluation. ![]()
