Serum electrolytes in children with neurocardiogenic syncope treated with fludrocortisone and salt

In conclusion, the treatment of syncope with sodium chloride supplement and fludrocortisone is associated with minimal and nonsignificant changes in serum electrolytes. The greatest change observed is an increase in serum bicarbonate. This change is not sufficient to require modification of the treatment. The added cost and discomfort associated with serial serum electrolytes testing do not appear to alter therapy.
