I gave the patient from yesterday 30 mg of tolvaptan. The repeat sodium was 128, up from 124 and urine sodium was down to 70, from 148 and the potassium was 40, down from 48. Urine output rose to 3425 mL.
The electrolyte free water clearance went from negative 1,364 to positive 481 mL.
The SIADH is due to West Nile Virus induced encephalitis.
