Les concentrations commerciales standard ne correspondent pas toujours aux besoins d\u2019un patient. Les unit\u00e9s de n\u00e9onatologie, par exemple, ont souvent besoin de concentrations interm\u00e9diaires, tandis que les patients soumis \u00e0 une restriction hydrique peuvent n\u00e9cessiter un apport plus important de dextrose dans un volume moindre.<\/p>\n<p>Lorsque deux solutions sont m\u00e9lang\u00e9es, la concentration obtenue se situe toujours entre les deux concentrations initiales&nbsp;: c\u2019est une moyenne pond\u00e9r\u00e9e dans laquelle la contribution de chaque solution d\u00e9pend de son volume. M\u00e9langer du D50 avec de l\u2019eau libre le dilue ; m\u00e9langer du D5 avec du D25 augmente sa concentration. C\u2019est pr\u00e9cis\u00e9ment ce principe de moyenne pond\u00e9r\u00e9e qu\u2019exprime la formule ci-dessus.<\/p>\n<p>Une source fr\u00e9quente de confusion est la diff\u00e9rence entre la concentration et la quantit\u00e9 totale de dextrose. Une poche de 100 mL de D10 et une poche de 1 000 mL de D10 ont la m\u00eame concentration (10&nbsp;%), mais apportent des quantit\u00e9s de glucose tr\u00e8s diff\u00e9rentes (10 g contre 100 g). Lors de la pr\u00e9paration de m\u00e9langes sur mesure, la concentration finale et le nombre total de grammes de dextrose administr\u00e9s comptent tous deux, en particulier chez les nourrissons et les patients soumis \u00e0 des objectifs stricts d\u2019\u00e9quilibre glyc\u00e9mique et hydrique.
