Role of vasopressin in hyponatremic dehydration

, , ,


Excessive correction of hyponatremia frequently occurs in the management of hyponatremic dehydration. This is more common in infants when correction of dehydration rapidly covers the hyponatremia faster than desired. This is the case of a 2½-month-old male infant with hyponatremic dehydration, which was overcorrected during the initial phase of treatment and was later managed by subcutaneous vasopressin. Vasopressin has got a dual role in the management of hyponatremic dehydration as it helps in dehydration correction as well as slow correction of sodium.
