Chemical Laryngitis Following Periprocedural Emesis

Area of Science:

• Otolaryngology
• Gastroenterology
• Critical Care Medicine

Background:

• Emesis (vomiting) exposes the larynx to acidic and enzymatic contents.
• Laryngeal injury from emesis is typically transient.
• Severe and prolonged laryngeal sequelae are uncommon.

Observation:

• Presents three distinct cases of severe laryngeal injury following periprocedural emesis.
• Details the unusual severity and duration of symptoms in these patients.
• Highlights the atypical nature of these laryngeal complications.

Findings:

• Identifies potential predisposing factors for severe laryngeal injury.
• Discusses the acute management strategies employed for these cases.
• Outlines methods to mitigate long-term consequences (sequelae).

Implications:

• Enhances understanding of rare but severe laryngeal complications of emesis.
• Informs clinical practice regarding risk assessment and patient monitoring.
• Provides guidance for managing and preventing adverse laryngeal outcomes.
