Boron Trifluoride

CAS RN:7637-07-2

Laboratory

A) Obtain at least hourly serum electrolytes including serial total or ionized calcium, magnesium, and potassium levels. Total calcium may not reflect true hypocalcemia, but usually has a more rapid turnaround. Therapy should be directed toward signs and symptoms of toxicity. Serum fluoride level may be used to confirm HF exposure. Obtain ABGs and chest X-ray in symptomatic patients.
B) Obtain serial ECGs looking for signs of hypocalcemia (prolonged QTc interval) and hyperkalemia (peaked T waves). Institute continuous cardiac monitoring.
