    Topicality of research: The metabolism of patients with thermal burns of different degrees and extent is affected by various factors. Thus, it is difficult to accurately predict the amount of energy required using only mathematical calculation methods such as the Harris-Benedict equation. The application of indirect calorimetry is particularly recommended for the development of nutritional therapy in critically ill patients to prevent the negative effects of under- and over-feeding. The dynamics of energy expenditure are complex, and clinical studies of indirect calorimetry in these patients are limited. Aim of the research: To measure rest energy expenditure in patients with body thermal burns using the indirect calorimetric method. Methods: A cross-sectional study was conducted. The study included 22 patients who, during the study period, were in the RAKUS State Burns Center's inpatient facility and were being treated for body thermal burns. The real basal metabolic rate (REE) was determined using the indirect calorimetry method. The indirect calorimetry device COSMED Q-NRG (COSMED – Metabolic Monitor for Indirect Calorimetry, n.d.-b) was used for the measurement. Results and conclusions: Indirect calorimetry shows a different resting metabolic rate compared to that measured by mathematical calculation equations. However, a statistically reliable, close positive correlation was observed between the measured basic metabolism and the one calculated by the Harris-Benedict equation. Compared with equations, indirect calorimetry is the method of choice to provide an efficient and accurate assessment of energy expenditure in patients with body thermal burns. Indirect calorimetry makes it possible to accurately assess the rest energy expenditure, as it takes into account not only anthropometric data, but also the current state of the disease and co-morbidities. The Cosmed Q-NRG calorimeter provides accurate and fast measurement of energy consumption. This device is particularly suitable for clinical use because it is easy to use and provides fast results. The measurements offer a personalized approach to measuring energy expenditure, which is particularly important for critically ill patients and patients with special nutritional needs.
