Calorias não nutricionais: o que fazer com elas? Estudo retrospectivo com pacientes COVID-19

Abstract

Introduction: During the intensive care unit (ICU) stay, the patient has caloric sources that do not come from nutrition, such as propofol. When these calories are not counted, it becomes a probable source of error in the critical patient’s energy calculation and it is already known that overfeeding is associated with many complications, including mortality. Our study aimed to assess the relevance of calories from propofol sedation in 51 mechanically ventilated intensive care (ICU) patients with COVID-19 receiving enteral nutrition. Methods: This is a retrospective study. Results: A total of 51 patients were recruited, 76% of patients receiving propofol during hospitalization. Among these, the average amount of calories from propofol was 260 (IQR 20-594) kcal. The proportion of calories in propofol was 15% (SD ± 8) of the total caloric value and the mean time of use was 8 days (SD ± 5.5). Conclusion: The conclusion we reached was that the calories from propofol were not relevant to exceed the proposed energy goal and increase the risk of hyperalimentation. However, in individual cases, the amount of calories can reach important values.
