Clinical Manifestations of Hyponatremia and Hypernatremia in Under-Five Diarrheal Children in a Diarrhea Hospital

To study clinical manifestations and outcome of hyponatremia and hypernatremia in children with diarrhea. We compared children aged 0-59 months hospitalized from 1 January to 31 December 2013 with hyponatremia (serum sodium 150 mmol/l) and normonatremia (serum sodium 135-145 mmol/l). The case fatality was significantly higher among the children with hypernatremia and hyponatremia than normonatremia. A logistic regression analysis adjusting for potential confounders revealed that children with hyponatremia are more likely to have convulsions, have severe acute malnutrition and be of older age compared with children with normal serum sodium. Children with hypernatremia are more likely to have convulsions and dehydration than normonatremic children (for all p
