Consequently, fluoride ions release, and further tissue destruction occurs. Actual incidence rate is unknown. Burns may involve underlying bone. Systemic fluoride ion poisoning from severe burns is associated with hypocalcemia, hyperkalemia, hypomagnesemia, and sudden death. Pain typically is described as deep, burning, or throbbing.
Pain often is disproportionate to apparent skin involvement.
Cardiac arrhythmias Additionally, obtain history of medications and intercurrent illness that predispose patient to hypocalcemia or hypomagnesemia. Surface involvement in these cases is minimal and may be absent. If burns to the fingers exist, perform digital x-rays to evaluate bone integrity. Arrhythmias are a primary cause of death. Monitor for QT prolongation from hypocalcemia or signs of hyperkalemia.
