Fatal hydrofluoric acid cutaneous exposure with refractory ventricular fibrillation.
A patient with hydrofluoric acid burns involving only 8% of his body surface area died from intractable cardiac arrhythmia secondary to the depletion of ionized calcium by fluoride ion. For burns of this type, immediate subcutaneous injection of 10% calcium gluconate into the burn wound is recommended and the dose given should be titrated to the relief of local pain. Immediate debridgement of the burn wound also can decrease the treacherous aspect of the circulating fluoride ion, which binds to calcium to form an insoluble salt, effectively removing the calcium ion from any physiologic interaction.
