Hladová, Eliška ; Hronek, Miloslav (advisor) ; Havel, Eduard (referee)
The aim of this work were examinations of septic patiens to determinate energy expenditure and the utilization of nutritional substrates and to compare results of examinations to standart recommendations of ESPEN for patient's nutrition. For investigations was used indirect calorimetry. Our group of septic patients consisted of three men and three women from 58 to 73 years old. The lenght of the hospital stay was different, so the group was heterogenous and each patient was in different phase of sepsis. Five of six patients were in hypermetabolism. The value of energy expenditure was from 87,3 % to 176,2 %. Average energy expenditure was 1790,3 ± 414,9 kcal/ kg/ day and average energy of nutrition was 2080,2 ± 754,7kcal/ kg/ day. As for nutritional substrates, average income of carbohydrates was 257,9 ± 109,9 g/ den. Average utilization of carbohydrates was 83,9 ± 62,1 g/ day. So the intake of carbohydrates were significantly higher, than the utilization. Average income of lipids was 63,6 ± 15,7 g/ day and average utilization was 102,1 ± 61,8 g/ day. There was also significant diference between lipid utilization and lipid intake. Average income of proteins was 127,4 ± 61,7 g/ day. Average utilization of proteins was 132,5 ± 53,6 g/ day. To conclusion, the results of examinations, measured by...
