On admission, the patient has hypervolemic hyponatremia, after 2 days of treatment with Inj. Furosemide becomes euvolemic. Later the patient shows skin triggers which concluded hypovolemic hyponatremia and treated with inj. Furosemide and 3% hypertonic solution, it increases cardiac output through an increase in effective blood circulation volume, improve inappropriate elevation of AVP and enhance effects of diuretics.
