Summary

Barium carbonate ingestion caused severe hypokalemia and paralysis. Continuous veno-venous hemodiafiltration (CVVHDF) effectively removed barium, improving muscle strength and neurological recovery within 24 hours.

Area of Science:

  • Toxicology
  • Nephrology
  • Critical Care Medicine

Background:

  • Severe hypokalemia and flaccid paralysis can result from toxic ingestions.
  • Barium carbonate is a highly toxic substance causing neuromuscular dysfunction.

Observation:

  • A patient presented with severe hypokalemia and quadriplegia after attempting suicide by ingesting amlodipine, fluoxetine, and barium carbonate.
  • Despite correcting hypokalemia, paralysis persisted, indicating a direct barium effect on muscle cells.

Findings:

  • Continuous veno-venous hemodiafiltration (CVVHDF) was initiated to manage barium intoxication.
  • CVVHDF tripled barium elimination, reduced serum barium half-life by three-fold, and stabilized potassium levels.
  • The treatment led to rapid improvement in motor strength and complete neurological recovery within 24 hours.

Implications:

  • CVVHDF is an effective treatment for severe barium poisoning, enhancing barium clearance.
  • This case highlights the critical role of renal replacement therapy in managing complex toxicological emergencies.
  • Early recognition and intervention with CVVHDF can significantly improve outcomes in barium intoxication.
