title: Evaluation of three oral rehydration solutions designed for use in developed communities.
abstract: One hundred and sixteen children (less than 2 years old) admitted to a London hospital with acute gastroenteritis were randomized to receive either an oral rehydration solution (ORS) with low sodium and high glucose concentration (Na+ 35, glucose 200 mmol/L), an ORS with a high sodium but low glucose concentration (Na+ 60, glucose 111 mmol/L), or an ORS containing glycine and a glucose polymer (Na+ 50, glucose 50, glycine 50 mmol/L). Clinical, biochemical and haematological features of the three groups were similar on admission. Rotavirus was common (31%); the majority of children had minimal dehydration or acid-base disturbance. The clinical outcome, including ORS intake, prevention of dehydration, rehydration, and duration of hospital stay was similar in the three treatment groups. All initial electrolyte abnormalities were corrected; no child developed hypernatraemia or hyponatraemia. At 24 h, the mean serum urea was higher in those who received the ORS containing glycine than in other groups, and it had not fallen significantly since admission. Eighteen per cent of children had carbohydrate intolerance: four children with greater than or equal to 2% reducing substances in their stool had all received ORS with a high glucose content and had numerous watery green stools containing rotavirus. All ORS solutions were safe and effective for rehydration and correction of biochemical abnormalities, however carbohydrate intolerance was more prevalent in children who received the ORS with a high glucose content.
