Nutritional status and enteral diet prescribed and received by patients of an intensive care unit
Main Article Content
Abstract
Introduction: Enteral nutrition represents a therapeutic possibility of maintenance or recovery of nutritional status. Therefore, as essential as the proper therapy prescription to the patient needs is the finding that he will receive what is prescribed. Objective: To verify the nutritional status of patients in use of enteral nutrition therapy, relating it to the adequacy of energy and protein value, and the volume prescribed and received during hospitalization in intensive care unit in a hospital in Santa Cruz do Sul, Rio Grande do Sul, Brazil. Methods: Quantitative retrospective descriptive observational study. We evaluated adult patients hospitalized in intensive care unit having an exclusive enteral nutrition therapy for more than 72 hours, from July to September 2011. It was considered satisfactory the adequacy ≥60% for calories and proteins correlating with the receiving and prescribing enteral diet, and ≥90% for the adequacy of the diet volume. For analysis of nutritional status, it was used the body mass index from a nonprobability sample of intentional character. Results: Thirty-six patients were analyzed. Of these, 16.7% was underweight and 44.44% was eutrophic. Approximately 44.4 and 22.2% of these patients reached ≥60% of prescribed calories and proteins, respectively, standing out those who were in an underweight nutritional status (p=0.012). Of the total patients, 36% reached the adequacy of volume without statistically significant difference from the nutritional status (p=0.771). Conclusion: It was found that most patients were in eutrophic nutritional status or overweight. Adults in critical condition received less enteral diet than prescribed.
