An open-label, inpatient study was undertaken to compare the efficacy of two
oral rehydration solutions (
ORS) given randomly to children aged 1-10 years who had acute
gastroenteritis with mild or moderate
dehydration (n = 45). One
solution contained 60 mmol/l
sodium and 1.8%
glucose, total osmolality 240 mosm/l (
Gastrolyte, Rhone-poulenc, Rorer) and the other contained 26 mmol/l
sodium, 2.7%
glucose and 3.6%
sucrose, total osmolality 340 mOsm/l (Glucolyte, Gilseal). Analysis of data indicated that
Gastrolyte therapy resulted in significantly fewer episodes and volume of
vomiting over all time periods in comparison to Glucolyte and significantly less stool volume during the first 8 h and in the 0-24 h period. The differences between treatments in degree of
dehydration at each follow-up period, duration of diarrhoea, and duration of
hospital stay were not significant. No
adverse drug reactions occurred. Six patients received intravenous
rehydration treatment and were considered treatment failures. We conclude that
oral rehydration therapy is safe and efficacious in the management of
dehydration in acute diarrhoea and that the lower osmolar
rehydration solution has clinically marginal advantages.
