“…As already demonstrated by Chawls in 1988 [23] and others [16,24], REE is much lower in ventilated critically ill children compared to healthy children and remains quite stable during the period of mechanical ventilation [25,26]. Several factors, such as sedation, analgesia, mechanical ventilation, reduced growth and physical activity, have been described to explain this decrease in energy needs [4,24].…”

“…Using the recommended dietary allowance as the caloric goal, Hulst et al observed that a cumulative caloric deficit of À100 kcal/kg was associated with a decrease in the z-score of weight-for-age in preterm and term neonates as well as in older children [29]. Only one study measured the total energy expenditure with doubly labelled water and REE with indirect calorimetry in critically ill children during and after weaning from mechanical ventilation [26]. The authors found than REE was 20% lower than the total energy expenditure with large inter-individual variations of physical activity measured by accelerometer.…”

“…In addition to IC, other methods, such as the doubly labelled water method and direct calorimetry, have been rarely used. Direct calorimetry has never been used in the PICU setting and the doubly labelled water method has been used in 1 study . In parallel, because IC is not practical in many patients, more precise predictive equations for REE need to be developed.…”

Provision of adequate energy intake to critically ill children is associated with improved prognosis, but resting energy expenditure (REE) is rarely determined by indirect calorimetry (IC) due to practical constraints. Some studies have tested the validity of various predictive equations that are routinely used for this purpose, but no systematic evaluation has been made. Therefore, we performed a systematic review of the literature to assess predictive equations of REE in critically ill children. We systematically searched the literature for eligible studies, and then we extracted data and assigned a quality grade to each article according to guidelines of the Academy of Nutrition and Dietetics. Accuracy was defined as the percentage of predicted REE values to fall within ±10% or ±15% of the measured energy expenditure (MEE) values, computed based on individual participant data. Of the 993 identified studies, 22 studies testing 21 equations using 2326 IC measurements in 1102 children were included in this review. Only 6 equations were evaluated by at least 3 studies in critically ill children. No equation predicted REE within ±10% of MEE in >50% of observations. The Harris-Benedict equation overestimated REE in two-thirds of patients, whereas the Schofield equations and Talbot tables predicted REE within ±15% of MEE in approximately 50% of observations. In summary, the Schofield equations and Talbot tables were the least inaccurate of the predictive equations. We conclude that a new validated indirect calorimeter is urgently needed in the critically ill pediatric population.).

“…It has become the gold standard for human energy requirement under daily living conditions (FAO/WHO/UNU 1985, 2004). Further applications include energy cost of clinical conditions (Van der Kuip et al 2007), activity costs in relation to body mass (Prentice et al 1996) and age (Speakman and Westerterp 2010), and under extreme conditions like endurance exercise (Westerterp et al 1986; Cooper et al 2011) and at high altitude (Westerterp et al 1992). …”

The doubly labelled water method for the assessment of energy expenditure was first published in 1955, application in humans started in 1982, and it has become the gold standard for human energy requirement under daily living conditions. The method involves enriching the body water of a subject with heavy hydrogen (2H) and heavy oxygen (18O), and then determining the difference in washout kinetics between both isotopes, being a function of carbon dioxide production. In practice, subjects get a measured amount of doubly labelled water (2H218O) to increase background enrichment of body water for 18O of 2000 ppm with at least 180 ppm and background enrichment of body water for 2H of 150 ppm with 120 ppm. Subsequently, the difference between the apparent turnover rates of the hydrogen and oxygen of body water is assessed from blood-, saliva-, or urine samples, collected at the start and end of the observation interval of 1–3 weeks. Samples are analyzed for 18O and 2H with isotope ratio mass spectrometry. The doubly labelled water method is the indicated method to measure energy expenditure in any environment, especially with regard to activity energy expenditure, without interference with the behavior of the subjects. Applications include the assessment of energy requirement from total energy expenditure, validation of dietary assessment methods and validation of physical activity assessment methods with doubly labelled water measured energy expenditure as reference, and studies on body mass regulation with energy expenditure as a determinant of energy balance.

Physical activity as a determinant of total energy expenditure in critically ill children

Abstract: During the week following pediatric intensive care admission, in the individual critically ill patient, activity related energy expenditure should be taken into account to prevent a negative energy balance.
