RESUMO
This study aimed at studying the serum sodium level in infants receiving home-mixed oral rehydration solution [ORS] for the prevention and treatment of dehydration caused by acute infantile diarrhea. It included 100 infants aged from 2-18 months, having received ORS at home during the last 24 hours. All cases were subjected to full clinical examination and to a questionaire about the amount, the reconstittution of ORS as well as any other food or additional fluids adminestered with it. The questionaire included also an inquiry on the source of knowledge of the mothers about ORS and feeding practice during diarrhea. Measurement of serum sodium proved that it ranged from 120-170 with a mean of 142.2 +/- 10.36 m Eq/Litre a value which though still within normal range was significantly higher than that reported for normal controls of matching age. Only 6% of patients showed a serum sodium level above 150 m Eq/Litre and all were asymptomatic. A positive correlation could be found only between serum sodium level and the degree of dehydration. The results were discussed
