Efficacy and safety of a modified oral rehydration solution (ReSoMaL) in the treatment of severely malnourished children with watery diarrhea

Abstract

Abstract OBJECTIVES:

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). STUDY DESIGN:

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. RESULTS:

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). CONCLUSIONS:

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
