Le point de d\u00e9part est le besoin \u00e9nerg\u00e9tique du patient. Ce calculateur estime la d\u00e9pense \u00e9nerg\u00e9tique de base (DEB) \u00e0 l'aide de l'<a href=\"https:\/\/wpcalc.com\/fr\/medical\/mifflin-st-jeor\/\">\u00e9quation de Mifflin-St Jeor<\/a>, qui est ensuite multipli\u00e9e par un facteur de stress refl\u00e9tant la demande m\u00e9tabolique de la pathologie sous-jacente \u2014 un patient \u00e0 jeun a besoin d'environ 1,1 fois sa DEB, tandis qu'un patient br\u00fbl\u00e9 peut avoir besoin de 1,6 fois sa DEB ou plus. Le r\u00e9sultat est le besoin calorique total (BCT) de la journ\u00e9e.<\/p>\n<p>Dans la NPT, les calories proviennent de trois sources&nbsp;: le dextrose (3,4 kcal\/g), l'\u00e9mulsion lipidique (1,1 kcal\/mL \u00e0 10&nbsp;%, 2,0 kcal\/mL \u00e0 20&nbsp;%) et les acides amin\u00e9s (4 kcal\/g). En pratique, les prot\u00e9ines sont prescrites en premier, sur la base du facteur prot\u00e9ique, et les calories non prot\u00e9iques restantes sont r\u00e9parties entre le dextrose et les lipides. Le calculateur soustrait les calories apport\u00e9es par le volume lipidique que vous avez saisi et affecte le reste au dextrose. Si les lipides sont r\u00e9gl\u00e9s sur 0 %, toutes les calories non prot\u00e9iques proviennent du dextrose.<\/p>\n<p>Le r\u00e9sultat final, le <strong>rapport calories non prot\u00e9iques\/azote (CNP:Az)<\/strong>, d\u00e9crit la quantit\u00e9 d'\u00e9nergie qui accompagne chaque gramme d'azote.
