In a retrospective survey, case notes of all children with acute gastro-enteritis (AGE) admitted to our hospital between 1984 and 1988 were reviewed. The total number of cases was 300. The mean age was 14 months (range 1-60 mths): 67% of cases were boys and 33% girls. Eleven per cent were exclusively breastfed. The clinical presentation was diarrhoea and vomiting in 81%, diarrhoea alone in 15%, and vomiting primarily in 4%. All children had good nutritional status, i.e. both their height and weight were between the 5th and 90th percentile for their age and none showed signs of marasmus or kwashiorkor. Forty-six per cent of the children had AGE without dehydration. Mild, moderate and severe dehydration was present in 41%, 10% and 3% of cases, respectively. Isotonic, hypotonic and hypernatraemic dehydration was present in 95%, 3% and 2% of cases of dehydration, respectively. Sixty-five per cent of cases were given intravenous (IV) fluids. The mean duration of IV administration was 1 day, with a range of 1-7 days. Twenty-two per cent of the children were given oral rehydration solution (ORS) initially, and 13% were given IV plus ORS. None of the children died of gastroenteritis. It is concluded that there was excessive use of IV fluids, and that there is an urgent need to encourage the use of ORS.
