Stool electrolytes in acute dehydrating gastroenteritis.

ABSTRACT

Stool electrolytes were studied in 100 cases of gastroenteritis. The duration of illness was 24-48 hours in 32% and 72-96 hours in 28% of the cases. On stool culture, 43% children had no growth, 23% had Enteropathogenic E. coli and 10% had cholera and rotavirus each. The stool sodium loss was more in cholera and shigella cases, diarrhea of shorter duration and in children between 24-30 months of age. Potassium loss in the stool was more in shiegella cases, diarrhea of short duration and in children between 30-36 months of age. In cases of gastroenteritis with severe malnutrition, stool sodium loss was less; stool potassium loss was not affected by the nutritional status. Total electrolytes lost in stools can be estimated by knowing purging rate and rehydration therapy can be planned accordingly.
