Table 2 ICU patient energy expenditure and nutrient intake per group

From: Malabsorption and nutritional balance in the ICU: fecal weight as a biomarker: a prospective observational pilot study

  < 350 g/day feces
(normal stools)
> 350 g/day feces
(diarrhea)
P value
Energy expenditure
TEE (kcal/day) c 2,068 ± 380 2,044 ± 361 0.872
Nutrient intake    
Energy (gross)    
(kcal/day) d 2,218 ± 626 1,941 ± 335 0.186
(kcal/kg/day) 29.1 ± 9.2 26.3 ± 6.1 0.370
Fat (g/day) 77.7 ± 22.4 72.0 ± 16.6 0.457
Protein (g/day) 93.1 ± 25.1 85.5 ± 17.9 0.372
(g/kg/day) 1.2 ± 0.3 1.2 ± 0.4 0.729
Carbohydrate (g/day) 236.9 ± 62.8 216.6 ± 35.8 0.335
  1. cTEE, total energy expenditure; n = 29. dEnergy intake is calculated as gross energy intake, not as energy intake available for metabolization (as is usual with regular calculation of nutrient intake)
