Avaliação de risco e estado nutricional, composição corporal e prognóstico em pacientes críticos de uma UTI de Pelotas, RS

Abstract

Severe or critical illness refers to the range of life-threatening clinical or surgical conditions that most often require hospitalization in an Intensive Care Unit (ICU). After an aggression, several metabolic and hormonal changes occur in order to maintain the body's homeostasis. This condition usually causes, among other effects, insulin resistance and protein catabolism, placing the patient at significant nutritional risk. Nutrition Risk Screening - 2002 (NRS -2002) and Nutrition Risk in Critical Ill (NUTRIC score) are nutritional screening tools indicated by ASPEN (2016) to evaluate nutritional risk parameters, being the first tool developed to evaluate ICU patients. However, nutritional screening only detects the presence of risk of malnutrition. The literature suggests, therefore, the use of the Global Subjective Assessment (SGA), still in a gold standard method to perform this type of evaluation in the hospital environment. From this, the present study had as objective to compare the prognostic power in critically ill patients, from the observation of the risk of death after 28 days of admission to the ICU, of NUTRIC and ASG in an isolated and combined way
