Summary
Severe hypernatremia in a teenager with acute kidney injury was successfully treated using continuous venovenous hemodiafiltration. This method allowed gradual correction of serum sodium, preventing neurological complications and ensuring full recovery.
Area of Science:
- Nephrology
- Intensive Care Medicine
- Neurology
Background:
- Rapid serum sodium changes can cause neurological damage.
- Gradual correction of hypernatremia is challenging in acute renal failure.
- Hypernatremia management requires careful electrolyte balance.
Observation:
- An obese female teenager presented with severe hypernatremia, hyperosmolar hyperglycemic nonketotic coma, acute renal failure, and rhabdomyolysis.
- The patient's condition necessitated intensive management of electrolyte imbalances.
- Continuous venovenous hemodiafiltration was employed for treatment.
Findings:
- Repeated adjustments to dialysate electrolyte composition during continuous venovenous hemodiafiltration gradually corrected hypernatremia and other serum chemistries.
- The patient experienced a full recovery of renal function.
- No clinical neurological sequelae were observed during a 1-year follow-up.
Implications:
- Continuous venovenous hemodiafiltration with adjusted dialysate is an effective strategy for managing severe hypernatremia in acute renal failure.
- This approach can prevent neurological complications associated with rapid sodium correction.
- The case highlights the importance of tailored fluid and electrolyte management in critically ill patients.
