Introduction:

Because of the proinflammatory state and catabolism that characterizes the critically ill patients have a high risk of malnutrition, which may, in combination with other factors, contribute to the dysfunction of the respiratory muscles and increase the duration of ventilation mechanics. The modified NUTRIC tool has shown its capacity to identify critically ill patients with greater nutritional risk and to correlate with clinical results.

Objective:

The objective of this study was to compare the NRS and NUTRIC score with the days of mechanical ventilation in critically ill patients.

Material and methods:

Observational retrospective cohort of 60 patients hospitalized in the ICU, where the NRS and NUTRIC scores were compared with the days of mechanical ventilation in critically ill patients. Daily records of patients of the Intensive Care Unit of Adults and electronic files were used, from which demographic, medical, NUTRIC and NRS scores were obtained.

Results:

The average age in this study was 43 ± 18 years, and 63% (38) were female. The average of the APACHE score was 19.9 ± 9, and that of the SOFA score of 10.1 ± 4.8. The NUTRIC score had an average of 5 ± 1.9 points, and the NRS, of 3.5 ± 1.1 points. The patients required mechanical ventilation an average of 4.6 ± 4.1 days.

Conclusion:

A significant correlation was found between the NUTRIC score modified with the days of mechanical ventilation, contrary to what was found when correlating with the NRS score. In the group of patients with high NUTRIC score had a significantly higher number of deaths, compared with those with low score.
