Сlinical cases of symptomatic hyponatremia

Abstract


The case series of four symptomatic hyponatremia in patients with cerebral diseases are analyzed. In all cases hyponatremia was severe (serum sodium level < 125 mmol/L) with the signs of cerebral edema, and poorly corrected. For the correction of hyponatremia, we used the intravenous infusion of 7.5% NaCl, and the average rate of correction was 9 mmol/L per day. The clinical signs of hyponatremia mimic as ischemic stroke and epilepsy. The moderate level of hyponatremia (125–129 mmol/L) did not correspond to the symptoms of cerebral edema. The most possible causes of hyponatremia were: traumatic brain injury, administration of X-ray contrast and furosemide, and infusion of 5% dextrose. Except the main suspected causing factor, all patients had several other factors that could predispose the development of hyponatremia. All patients presented with hypochloremia.
