We appreciate Dr Greenough's comments and agree that additional study with the low-osmolar rice-based oral rehydration solutions (ORSs) would be warranted. We chose Pedialyte as our ORS because it is widely available to all emergency departments and patients. Although Pedialyte is technically a maintenance solution, it has been shown to be effective as a rehydration solution. Our use of Pedialyte was specifically designed to demonstrate that using oral rehydration therapy for moderately dehydrated children does not require obtaining ORSs that are not readily available in almost every emergency department, drug store, and grocery store in the United States.
