A Rare Toxic Agent in the Emergency Department: Sulphur Hexafluoride

Abstract

Introduction: Although sulfur hexafluoride (SF-6) is considered biologically inert, it may cause asphyxia and death, replacing oxygen. SF-6 is used in many areas, varying from medical devices to the aerospace industry. Case Report: Two electricity workers, who were 19 and 32 years old, were admitted to our emergency deperatment with complaints of nausea, vomiting, and dizziness after SF-6 exposure of about 5-10 minutes because of malfunction of their high-voltage circuit breaker. At admission, the general condition and mental status of both patients were good. Their vital signs were stable. The patients, with normal physical examination findings, were hospitalized to the emergency observation unit for follow-up and treatment. Both patients were discharged after follow-up. Conclusion: Although it is considered chemically and biologically inert, a rare toxic agent in the emergency department, SF-6, has a risk of death in acute exposure. Monitoring and follow-up of these patients are necessary for reducing fatal complications.
