Is Electrolyte Maintenance Solution Required in Low-Risk Children With Gastroenteritis?

Gastroenteritis remains a major cause of morbidity amongst Canadian children. The primary treatment focus revolves around the use of Oral Rehydration Therapy (ORT) to treat dehydration and replace intravascular volume. Since diarrheal disease in Canadian children usually results in mild dehydration and minimal sodium losses, the use of low sodium Electrolyte Maintenance Solutions (EMS) has become the standard of care. However, given that North American children infrequently develop severe dehydration, it is unclear if the routine use of EMS is justified. When pediatricians directly dispense EMS, 16 children need to be treated to prevent 1 unscheduled office visit, however the upper bound of the 95% confidence interval is an astounding 508 patients. In addition, EMS is considered by some to be prohibitively expensive, with 15% of pediatricians believing it to be too expensive for their patients to purchase. An additional 40% report that taste is a major barrier to consumption. As a result, oral fluid replenishment is often underutilized and IV rehydration employed instead. Our goal is to provide evidence to guide the selection of the optimal ORT fluids in low-risk children, thus increasing its use, enhancing its success, and reducing the reliance on intravenous rehydration. We hypothesize that the strict adherence to EMS use in low-risk children may actually be counterproductive by resulting in reduced fluid intake and potentially increasing the use of intravenous rehydration.
