Abstract

To develop evidence-based hypoglycemia treatment protocols in patients receiving total enteral nutrition, this study determined the effect on enteral tube flow of glucose therapy agents: apple juice, orange juice, and cola, and it also examined the effects of tube type and feed type with these glucose therapy agents. For this study, 12 gastrostomy tubes (6 polyethylene and 6 silicone) were set at 50 mL/h. Each feeding set was filled with Isosource HN with fibre or Novasource Renal. Each tube was irrigated with 1 glucose therapy agent, providing approximately 20 g of carbohydrate every 4 h. Flow-rate measurements were collected at 2 h intervals. The results showed that the glucose therapy agent choice affected flow rates: apple juice and cola had higher average flow rates than orange juice (P = 0.01). A significant difference was found between tube type and enteral formula: polyethylene tubes had higher average flow rates than silicone tubes (P < 0.0001), and Isosource HN with fibre had higher flow rates than Novasource Renal (P = 0.01). We concluded that apple juice and cola have less tube clogging potential than orange juice, and thus may be considered as primary treatment options for hypoglycemia in enterally fed patients. Polyethylene tubes and Isosource HN with fibre were less likely to clog than silicone tubes and Novasource Renal.

Résumé

Afin d’élaborer des protocoles thérapeutiques fondés sur des données probantes pour l’hypoglycémie chez les patients alimentés par voie entérale seulement, cette étude a examiné l’effet sur le débit dans la sonde entérale des agents régulateurs de la glycémie suivants : le jus de pomme, le jus d’orange et le cola. Elle a aussi examiné les effets du type de sonde et du type d’alimentation utilisés avec ces agents régulateurs de la glycémie. Dans le cadre de cette étude, 12 sondes de gastrostomie (6 en polyéthylène et 6 en silicone) ont été installées à un débit de 50 ml/h. Chaque sac d’alimentation a été rempli d’Isosource HN Fibre ou de Novasource Rénal. Chaque sonde a été irriguée avec 1 agent régulateur de la glycémie, fournissant environ 20 g de glucides toutes les 4 heures. Le débit a été mesuré à des intervalles de 2 heures. Les résultats ont montré que le choix de l’agent régulateur de la glycémie influençait le débit : le jus de pomme et le cola avaient des débits moyens plus élevés que le jus d’orange (P = 0,01). On a observé une différence significative en fonction du type de sonde et de la formule entérale utilisés : les sondes de polyéthylène avaient des débits moyens plus élevés que les sondes de silicone (P < 0,0001), et l’Isosource HN Fibre était associé à des débits plus élevés que le Novasource Rénal (P = 0,01). Nous avons conclu que le jus de pomme et le cola sont moins susceptibles de bloquer la sonde que le jus d’orange, et peuvent ainsi être envisagés comme options de traitement principal pour l’hypoglycémie chez les patients alimentés par voie entérale. Les sondes de polyéthylène et l’Isosource HN Fibre étaient moins susceptibles de causer un blocage que les sondes de silicone et le Novasource Rénal.
