“…(7) There is still no definition about the best method to measure energy metabolism of diseased obese patients, mainly those with a BMI over 40kg/m 2 . (21) In a study of critically ill patients with a BMI under 25kg/ m 2 and between 25 and 30 kg/m 2 receiving enteral and/ or parenteral nutrition and under mechanical ventilation, energy requirements were underestimated by IJ.…”

“…Energy expenditure was estimated by the improved Ireton-Jones equation, (7) according to chart 1. The body mass index (BMI) was estimated based on the weight/height formula (2) and classified according to values of the World Health Organization (WHO), 1999.…”

“…Пациенты оригинальной популя-ции были в возрасте 15-80 лет (в среднем 43 года), преимущественно мужского пола, 33% зависели от ИВЛ. В дальнейшем информативность уравнения была подтверждена в проспективном исследовании 100 пациентов со схожими характеристиками [27]. В 1997 г. авторы данного уравнения модернизиро-вали его, обследовав 99 пациентов на ИВЛ и обна-ружив, что оригинальное уравнение переоценивает энергетические потребности пациентов в среднем на 271 ккал/сут [27].…”

“…68 In 1979, Long et al 69 proposed modifications to the original Harris-Benedict equation to account for the metabolic fluctuations of critical illness: multiplying the basal energy expenditure by stress and/or activity factors. More recently, several predictive equations have been designed using critically ill patient populations, including those published by Swinamer et al, 70 Ireton-Jones et al, 71,72 and Frankenfield et al 73,74 A simpler formulaic approach recommended by the American College of Chest Physicians 1997 consensus statement is the use of "kilocalorie per kilogram" (kcal/kg), with energy goals in the critically ill patient population of 25 kcal/ kg/d. 75 A range of 20 -25 kcal/kg/d is considered an appropriate target for critically ill patients, to avoid over-and underfeeding.…”
