Nutritional Status, Muscle Wasting and Fraility in Intensive Care Patients

Karadeniz Technical University44 enrolled

Overview

The risk of muscle wasting is high in the intensive care unit patients during the treatment process and this condition is associated with adverse clinical outcomes. The etiology of muscle wasting is multifactorial and medical nutrition therapy plays a key role in muscle wasting treatment and prevention. The aim of this study is assesing the malnutrition and fraility, anthropometric measurements, and muscle mass by ultrasound at the first admission to the intensive care unit and to determine the nutritional factors affecting clinical outcomes. In addition, it is planned to determine the risk factors affecting the change of anthropometric measurements and muscle wasting in the first week during the intensive care unit.

A nutrition-focused physical examination is an integral component in the assessment of critically ill patients. Malnutrition, muscle wasting, and frailty are multidimensional clinical conditions in critically ill patients and are associated with adverse outcomes. Although malnutrition, muscle wasting and frailty are linked, the exact relation between them is unsure. As a result of evaluating these conditions together, it is planned to develop new treatment strategies and to improve the clinical results of patients by determining the relationship between medical nutrition therapy.
