Avaliação do estado nutricional de pacientes em Terapia Nutricional Enteral de uma Unidade de Terapia Intensiva

Abstract

O presente estudo teve como objetivo avaliar o estado nutricional de pacientes em uso de Terapia Nutricional Enteral (TNE) durante a internação em Unidade de Terapia Intensiva (UTI) de um hospital público da cidade de Teresina, Piauí. Trata-se de um estudo transversal realizado com 31 pacientes em uso de TNE admitidos na UTI. O estado nutricional foi avaliado por parâmetros objetivos antropométricos e bioquímicos e por avaliação nutricional subjetiva global. Dos 31

Nutritional status association with protein-calorie adequacy in critically ill patients admitted to an intensive care unit

“…Our study also found high values of urea. This was similar to a result also found in one study that presented a high mean value of urea (72.9±45.3 mg/dl) 8 , and another, which found that 19 out of 20 patients had values higher than recommended for serum urea (95%). Urea is used as an indicative measure of renal failure, and when below the recommended level, it tends to illustrate a lack of proteins in the body 29 , but this measure can be induced by other factors not related to from renal function 8 .…”

“…This indicates muscle catabolism. A similar study evaluated the nutritional status in 31 patients in an intensive care unit, where patients also had high creatinine values 8 .…”

“…Only two achieved caloric adequacies of ≥80% during the evaluation period. This should be monitored, especially in critically ill patients admitted to the ICU, as studies point that better caloric adequacies lead to better adherence to ENT, lower mortality rates, and shorter hospitalization periods 4,8 . It also prevents declines in the immune response, changes in body composition, and malnutrition.…”

“…It is essential for patient recovery, maintaining the nutritional status, lowering infection complications, balancing the immune system and preventing malnutrition. However, the ENT must be constantly monitored, offering macro and micronutrients according to the needs of each patient and giving prioritizing adequate protein supply 4,8 .…”

“…However, there are no gold standard methods for this assessment. Because of this, it is feasible to use all available methods, allowing greater reliability at the time of the nutritional evaluation 8 .…”
