Energy Requirements in Critically Ill Patients

Nutritional Assessment in Critically Ill Patients

Background: Malnutrition is an important factor in the survival of critically ill patients. The purpose of the present study was to assess the nutritional status of patients in the intensive care unit (ICU) on the days of admission and discharge via a detailed nutritional assessment. Methods: Totally, 125 patients were followed up from admission to discharge at 8ICUs in Shiraz, Iran. The patien...

ASSESSMENT OF ENERGY EXPENDITURE AND ENERGY INTAKE IN CRITICALLY ILL PATIENTS Energy Expenditure and Intake in Critically Ill Patients

Objective: To measure the energy expenditure (EE) of critically ill patients and to determine the adequacy of energy intake in terms of nitrogen balance. Research Methods & Procedures: Indirect calorimetry was performed in 17 critically ill patients under mechanical ventilation in order to calculate EE, and 24 h urinary nitrogen excretion was determined in order to calculate the nitrogen balanc...

Prediction equations to determine caloric requirements in critically ill patients.

The ability to predict resting energy expenditure in a given individual during critical illness is very difficult. The unreliability of prediction equations to determine caloric requirements in critically ill patients is well established.1-17 The stress response to a specific insult is not identical across individuals, which further impairs the accuracy of prediction equations. Even the variabl...

Comparison of measured versus predicted energy requirements in critically ill cancer patients.

BACKGROUND Accurate determination of caloric requirements is essential to avoid feeding-associated complications in critically ill patients. METHODS In critically ill cancer patients we compared the measured and estimated resting energy expenditures. All patients admitted to the oncology intensive care unit between March 2004 and July 2005 were considered for inclusion. For those patients enr...
