Critical illness demands objective, targeted nutritional therapy to prevent adverse effects of underfeeding/ over feeding. Thus, all recent societal guidelines recommend indirect calorimetry use to determine energy needs. Current commercially available indirect calorimeters are often inaccurate, and the inconveniences have led to significant challenges to routine indirect calorimetry use in ICU...
A major driver leading to the lack of emphasis on timely ICU nutrition delivery is lack of objective data to guide nutrition care. If we are to ultimately overcome current fundamental challenges to effective ICU nutrition delivery, we must all adopt routine objective, longitudinal measurement of energy targets via indirect calorimetry (IC). Key evidence supporting the routine use of IC in the ICU...
The current review aims to summarize the complex relationship between SARS-CoV-2 infection and nutritional status and the effects of malnutrition in terms of disease severity, patients’ recovery time, incidence of complications and mortality rate. In COVID-19, this relationship has shown to be crucial across the disease phases, particularly in people at risk for a poor prognosis, including obese,...
Nutritional and metabolic disturbances are observed in patients critically ill with COVID-19. At each step of the progression of the disease, ICU patients with COVID-19 should be carefully evaluated in terms of malnutrition risk and medical nutritional support. The tremendous challenges posed by the continuous clinical changes requires adequate answers at each stage. The analysis of new data...
The use of indirect calorimetry (IC) is increasing due to its precision in resting energy expenditure (REE) measurement in critically ill patients. Thus, this study aim to evaluate the clinical outcomes of an IC-guided nutrition therapy compared to predictive equations strategy in such a patient population. This systemic review and meta-analysis indicates that IC-guided energy delivery significantly...
