Area of Science:

  • Toxicology
  • Cardiology
  • Emergency Medicine

Background:

  • Inhalant abuse, particularly of compressed air dusters containing difluoroethane, is a growing concern.
  • Volatile solvent abuse can lead to serious, life-threatening medical emergencies.
  • Cardiac complications from inhalant abuse are well-documented but severe presentations are rare.

Purpose of the Study:

  • To report a rare case of severe cardiac dysfunction and arrhythmia following the abuse of difluoroethane.
  • To emphasize the potential for significant cardiovascular sequelae from inhalant abuse.

Main Methods:

  • Case report of a 34-year-old male presenting after intentional inhalation of fifteen cans of Dust-Off.
  • Clinical evaluation including neurological assessment, cardiac monitoring, and echocardiography.

  • Documentation of resuscitation and recovery course.

    • Main Results:

    • The patient experienced a generalized seizure and torsades de pointes arrhythmia requiring resuscitation.
    • Echocardiography revealed severe biventricular dysfunction with a markedly reduced ejection fraction (25%).
    • The patient demonstrated full recovery with normalization of ejection fraction prior to discharge.

    Conclusions:

    • Difluoroethane inhalant abuse can precipitate acute, severe cardiac dysfunction and life-threatening arrhythmias.
    • Prompt recognition and management are crucial for patient survival and recovery.
    • This case underscores the critical importance of considering inhalant abuse in patients presenting with unexplained cardiac events.
