Combined treatment of severe hyponatremia due to inappropriate antidiuretic hormone secretion
Insights
Severe hyponatremia in a child post-surgery was treated with hypertonic saline and furosemide. Adding deoxycorticosterone acetate (DOCA) rapidly normalized sodium levels and improved the patient's condition.
Area of Science:
- Pediatric Endocrinology
- Neurosurgery
- Nephrology
Background:
- Craniopharyngioma surgery can lead to complications affecting fluid and electrolyte balance.
- Syndrome of Inappropriate Antidiuretic Hormone (SIADH) secretion is a potential post-operative complication causing severe hyponatremia.
Observation:
- A 6-year-old girl presented with seizures and coma post-craniopharyngioma surgery.
- Laboratory findings confirmed severe hyponatremia and SIADH with high urinary sodium excretion.
Findings:
- Initial treatment with hypertonic saline and furosemide showed slow improvement in serum sodium levels.
- Addition of deoxycorticosterone acetate (DOCA) resulted in rapid normalization of serum sodium and decreased urinary sodium output.
Implications:
- DOCA, in conjunction with hypertonic saline and furosemide, offers an effective treatment for severe, life-threatening hyponatremia due to SIADH.
- This case highlights the potential benefit of mineralocorticoid therapy in managing complex electrolyte disturbances post-neurosurgery.
Abstract:
A 6-year-old girl developed generalized seizures followed by coma, five days after surgical removal of a craniopharyngioma. Low serum sodium levels and low serum osmolality with inappropriately high urinary sodium output confirmed the diagnosis of inappropriate antidiuretic hormone (ADH) secretion. Treatment with 3% hypertonic saline solution and repeated doses of furosemide (1 mg/kg) improved her clinical condition; serum sodium levels, however, rose slowly and urinary excretion remained high. Deoxycorticosterone acetate (DOCA), 4 mg/sq m/day, was added to the above regimen. A striking clinical improvement was noted. Serum sodium levels returned to normal with a concomitant sharp decline in urinary sodium output. The clinical course of this patient demonstrates the efficacy of the addition of deoxycorticosterone acetate to hypertonic saline and furosemide in the treatment of severe, life-threatening hyponatremia due to the syndrome of inappropriate antidiuretic hormone secretion.
