Arsine Poisoning Follow-up
- Author: Kermit D Huebner, MD, FACEP; Chief Editor: Robert G Darling, MD, FACEP more...
Further Inpatient Care
- All patients who have suspected arsine exposure should be carefully observed for 24 hours.
- Monitor renal function; initiate hemodialysis as necessary for acute renal failure.
- Monitor hemoglobin levels; perform transfusions to maintain oxygen-carrying capacity of the blood.
Further Outpatient Care
- Monitor the patient for signs of chronic arsenic toxicity.
Inpatient & Outpatient Medications
- Chelating agents (eg, BAL) may be used to treat chronic arsenic toxicity.
- Chronic arsenic toxicity from arsine exposure is treated no differently than exposure from other sources.
- See Toxicity, Arsenic for more information.
Deterrence/Prevention
- Train workers in high-risk industries to avoid toxic arsine exposures.
- Screen workers in the same environment as those persons already exposed to acute arsine poison.
Complications
- Renal failure
- Death
- Overwhelming exposures cause rapid death from massive hemolysis.
- In those who survive acute exposures, most deaths occur from renal failure.
- Chronic arsenic toxicity: Patients who survive acute arsine exposure may develop chronic arsenic toxicity, including anemia and peripheral neuropathy.
Prognosis
- Patients who reach medical attention should survive with modern, supportive medical care.
- Historically, patients who developed renal failure had 100% mortality. More recent (but still dated) studies report a mortality rate from arsine poisoning of approximately 25%.
