WHAT’S NEW
Kids drink more of what they like
This study, in a developed country, found rehydration with diluted apple juice worked just as well as ORT. In children ≥24 months of age, there were fewer treatment failures.
CAVEATS
Infants may not benefit,and ondansetron played a role
In this study, children were only mildly dehydrated. Also, the study did not include infants younger than 6 months of age, and the greatest benefit was in children ≥24 months of age.
Also noteworthy was the role that oral ondansetron played. Most (67.4%) of the children received an oral dose of ondansetron (0.1 mg/kg). Although expensive, if one dose prevents a hospitalization, it is cost-effective. Previous studies of oral ondansetron show it reduces vomiting (NNT=5); lowers the rate of intravenous hydration in the ED (NNT=5); and reduces the hospitalization rate from the ED (NNT=17).10
Lastly, there are a variety of fluid replacement guidelines. In this study, fluid replacement was 2 mL/kg for a vomiting episode and 10 mL/kg for a diarrhea episode.
CHALLENGES TO IMPLEMENTATION
Given the ease of swapping diluted apple juice for oral rehydration therapy, we see no barriers to implementation.
