ABSTRACT OBJECTIVE: To evaluate the acute nutritional status of a group of patients hospitalized in a pediatric ICU by measuring the nitrogen balance, and to evaluate the impact of a greater diet intake in this same balance. METHODS: A prospective cohort study conducted from March to June 2018, with children between the ages of 29 days and 14 years, with bladder catheter by the need of his own treatment. The collection of 24-hour urine was performed to calculate the nitrogen balance, which was classified like positive (BN > 0) or negative (BN < 0) for the analyzes. RESULTS: 40 patients were evaluated, with a second sample of 24-hour urine in 7 of them. Of the 47 samples, 25 (53%) had a positive nitrogen balance. Of this samples with positive nitrogen balance, the mean protein and caloric intake found was of 1.4 g/kg/day and 61 Kcal/kg/day, respectively. From the patients that we collected a second 24-hour urine sample, this time with a higher diet intake, the nitrogen balance of the second samples were statistically higher than the first, with a p-value of 0.018. CONCLUSION: We conclude that an increase in caloric and proteic intake results in an improvement of the nitrogen balance. The numbers we found of caloric and proteic intake to reach a positive nitrogen balance were similar to other studies found in literature. KEYWORDS Nitrogen balance, PICU
