Efficacy, development of overhydration, and correction of electrolyte disturbances of severely malnourished children with acute diarrhea using a modified oral rehydration solution for malnourished children (termed ReSoMaL and recommended by the World Health Organization [WHO]) were evaluated and compared with standard WHO-oral rehydration solution (ORS).


Children age 6 to 36 months with severe malnutrition and acute watery diarrhea were randomized to ReSoMaL (n=65) or standard WHO-ORS (n=65). Major outcome measures included the number of children who developed overhydration and the number who corrected hypokalemia.


The numbers of children who developed overhydration were not significantly different (ReSoMaL vs WHO-ORS, 5% vs 12%, P=.2). ReSoMaL corrected basal hypokalemia in a greater proportion of children by 24 hours (36% vs 5%, P=.0006) and 48 hours (46% vs 16%, P=.004) compared with WHO-ORS. More children on ReSoMaL than WHO-ORS remained hyponatremic at 48 hours (29% vs 10%, P=.017). Three children in the ReSoMaL group developed severe hyponatremia by 24 hours, with one experiencing hyponatremic convulsions (serum sodium, 108 mmol/L).


ReSoMaL has a large beneficial effect on potassium status compared with standard ORS. However, ReSoMaL therapy may result in symptomatic hyponatremia and seizures in patients with severe diarrhea.
