In Canada, acute gastroenteritis remains a major cause of morbidity and hospitalizations. This, in large part, is due to an inability to realize the full benefits of oral rehydration therapy. Because oral rehydration solutions have a salty taste, many mild to moderate dehydrated children refuse to drink them. This has resulted in pediatricians recommending inappropriate solutions and the unnecessary administration of intravenous fluids. Although two meta-analyses have concluded that rice-based ORS (Enfalyte) is as or more effective than traditional ORS in reducing stool output, the palatability of different oral rehydration solutions have never been evaluated.

This will be the first prospective trial comparing the palatability of the most commonly recommended oral rehydration solutions, Pedialyte and Enfalyte with a newer solution, Pediatric Electrolyte. Both Pedialyte and Pediatric Electrolyte contain sucralose, dextrose, and fructose while Enfalyte contains rice syrup solids. Although the latter is as, or more effective than Pedialyte in reducing stool output, palatability may limit its use. Taste is important as children with gastroenteritis are frequently nauseated and may refuse to drink or vomit when consuming less palatable solutions.

We hypothesize that, compared to children who receive a rice-based ORS (Enfalyte), those who receive a sucralose ORS (Pediatric Electrolyte or Pedialyte) will report a higher mean taste score, will prefer to drink the sucralose sweetened ORS if they had to consume a larger volume, and are more likely to drink the entire volume they are provided.
