Early syndrome of inappropriate secretion of antidiuretic hormone in a child with burn injury.

A 17-month-old boy presented with 10% to 12% first- and second-degree burns secondary to scald injury. He rapidly developed hyponatremia secondary to inappropriate antidiuretic hormone secretion, manifested by the occurrence of seizures. After appropriate therapy was instituted, the child had an uneventful recovery. To the best of the authors' knowledge, this problem has not been reported previously in a child with a relatively mild burn.
