Inducible laryngeal obstruction in a healthcare worker exposed to hydrogen peroxide, peracetic acid, and acetic acid.

This report describes a case of severe inducible laryngeal obstruction (ILO) in an emergency department nurse. Onset of the condition occurred after an episode of exposure to a disinfectant product containing hydrogen peroxide, peracetic acid, and acetic acid. Previously exposures had been tolerated by the nurse over a period of nine months. Influenza infection may have been a predisposing factor. Despite various interventions, including botulinum toxin A injections, suture lateralization of the right true vocal cord, and right CO2 laser transverse cordotomy with partial medial arytenoidectomy, the patient continued to experience severe symptoms. Ultimately, a tracheostomy was performed to alleviate the obstruction. This case highlights the need for heightened clinician awareness, early and accurate diagnosis, and the development of effective management strategies for ILO patients.
