Oral rehydration solutions may not be appealing to children owing to poor palatability, and consequently many mild to moderately dehydrated children may refuse to consume these solutions. This randomized crossover trial was conducted to determine whether 5- to 11-year-old children report taste differences between 3 oral rehydration solutions. There were significant differences regarding the best-tasting solution, with Pedialyte selected by 53%, Pediatric Electrolyte by 39%, and Enfalyte by 8% of the participants. Children were least willing to drink the Enfalyte again. Sucralose-sweetened solutions such as Pedialyte and Pediatric Electrolyte are significantly more palatable than the rice-based preparation Enfalyte. Given the similar content of the solutions evaluated and that the sucralose solutions are less expensive, perhaps they should be recommended as initial therapy.
